There's a great troubleshooting section on the samba for the FI. You had the injectors out, so you must replace the seals! Also those rubber S boots can have cracks and will cause a no run issue. Don't let anyone talk you into ripping it out for carbs, its an awesome system.

Mechanical problem that is where I would start. Injection working fine. My best guess.......Valve seat stuck and valve not closing all the way. Clicking noise from lifter loose because seat has moved a bit....If that is the issue dont run the engine at high rpm....you will loose a piston. This happened daily at the shop I worked at in the 80s.

My first thought is to replace the square fuel filter, check for broken vacuum lines and make sure they are hooked up correctly. I would then look at the fuel pressure regulator. I love my 76 fuel injected bus! When they are running good.. it’s hard to beat a fuel injected bus! So reliable and smooth. I learned one thing about them… fuel injected VW love to be all stock. I messed with so many aftermarket distributors and electronic ignitions and found out it runs best with the original points style distributor. Good luck!

I feel for you guys. It took me a while to figure mine out. But it came down to a vacuum leak. The little rubber elbow on the right side of the motor toward the middle had a tear in it. At first I just pulled it out and wrapped it with electrical tape and put it back on. It fired right up. It’s hard to see due to it being right under the air cleaner and the blower for the heater. It’s to the right of the enrichment injector. Unfortunately once I figured it out that’s when I was able to get it to stay running long enough to hear the number three valves rattling around in the head due to loose valve seats. Good luck guys.

@riverbluevert7814 2 жыл бұрын

Here's another thing to check. And it's a quick one. It's possible that you're getting too much fuel and flooding within a few seconds after starting. Temperature-sensor-2 is attached to one of your cylinder heads. (It's cylinder 4 on a Bug) Pull the spade connector for this sensor off the harness. The resistance from the connector to the crankcase should be about 2500 ohms. If the TS-2 is defective and open circuit, the ECU commands FULL RICH and floods the engine after starting.

@djambrosia 2 жыл бұрын

You have ruled out the ignition system, AFM and ECU as when it runs on brake clean you have a consistent injector pulse and spark but judging by the "dribbling" injectors I would suspect a fueling issue. Place an inline fuel pressure gauge fitted somewhere before the pressure regulator. Cycle the ignition a few times to prime the system and you should read around 35 psi. If not then pinch the inlet pipe after the gauge but before the regulator and cycle the key once more. If you see a reading lower than 35psi I would suspect the pump or a blockage up stream. A reading higher than 35psi would indicate a failed regulator. Assuming you see around 35psi leave it for a couple of minutes and if the pressure holds the regulator is good. Start the engine and the psi should drop to around 30 psi at idle with the vacuum hose connected. If the pressure immediately drops away you have a pump/blockage issue. If the pressure is maintained stop the engine, pull the injectors and watch for any drips (No more than a couple a minute). Replace any injectors that drip and try again. If the injectors are good then Dellorto's are the answer.

DONT HOLD THE CONNECTION FOR VERY LONG WITH THE 9V battery you will FRY the injector. Remember these type 4 engines had issues with valve seats. could be low compression from compromised valve seat.

Great step by step process of elimination effort. I really think you have something interrupting fuel delivery from tank to injectors, debris in tank or line that temporarily clogs the filter/line, then when pump is off for enough time, the non-suction allows it to drop away allowing a temporary restart. So glad I have carbs 😉

@oldtanker4860 2 жыл бұрын

Watching the trials that you went through I kept thinking back to fuel issues. While the pump is running, is it supplying enough pressure. A pressure gauge might be a good thing to check with. In addition fuel filter / lines for flow in case there is an obstruction in either one. Just as a final check I'd see if you can get the injectors cleaned and then clean all the electrical connections on the airbox.

The inlet screen/filter for the fuel pump is full of rust, when the pump comes on it sucks all the crud up and chokes itself off. After the van sits for a minute the rust settles to the bottom again and it will fire up and run momentarily until it sucks all the rust back up.

Judging by the looks of things, what I would suggest to you guys is get a bench testing fuel injector tool that feeds gas/12V to the injectors, you hook them in line of everything, and watch the spray pattern. If it isn't a consistent strong mist and appears sporadic, they're clogged or failing. If there are 12V positive and ground connections on said injectors, take a 9V battery and quickly touch the connections back and forth to hear whether or not the injector solenoids are actuating. If they stick after you rip away the battery or don't articulate, you have a failed injector. I'd also check resistance on your fuel pump if it's running a 12V fuel pump, as well as check fuel pressure, could be a failed fuel pump. You guys obviously have spark since it runs, so converting from a pointless ignition to a points ignition won't necessarily solve your problem right away, wouldn't worry about that. Keep us all posted on what you find! Type 4 fuel injected buses and vanagons are a very finicky anomaly! Chrisfix on KZfaq here has an excellent video on testing fuel injectors that encompasses any brand, a fuel injector is pretty consistent for any design until you go to GDI technology, that's when complexity takes place.

Don't pull it! Replace all vacuum lines. There is little "T" connecting under the alternator that may be where the leak is. Also the sweeper plate may need to be moved. Download the AFC pdf from the samba. You are going to need to check the resistor pack. Put a pressure gauge on the rail, drivers side permanently. I got a water pressure gauge from home depot and use a little piece of hose. Still cant rule out fuel pump. You will get it and be glad you did not replace it.

@VochoTalacha 2 жыл бұрын

The fuel pump is not providing enough pressure. The fact that brake cleaner keeps it working, then you know it's fuel pump pressure. The injectors spray way too little fuel, as the spray pattern has to be like that on the brake clean can, and the little squirt you're getting after a couple of seconds is not enough. Just compare it when it works, the injectors spray like they should, then they go to a wee little spit of fuel. Get anew fuel pump and that'll solve the issue. It's that or there's a vacuum leak that causes the fuel pressure regulator to bypass and send all the pressurized fuel back to the tank.

@Mikefngarage 2 жыл бұрын

yea I second that. But I also hear a lot of clicking. and an uneven crank. sounds like one cylinder not doing very well....From past experience it probably has a valve seat coming loose. I would clean every injector with a 9v battery and check fuel pressure. also check compression. combination of a few things.

5 minutes into the KZfaq I thought this is GREAT. They have the same problem like I have, running for a few seconds after it was of for a while. So I was quite disappointed when you finally gave up. BUT it pushed me to get going and I FINALLY found the problem. I went through many checks, a few twice or three times and found other issues. Finally I checked Ohm readings at the 35 pin ECU connector and measured the pin 13 to ground which is the head temperature sensor it was open. One side of the connector was 0 Ohm (pin 13 to that point) and the other infinity. The connector came easily apart, must have been all the wiggling of the nearby injectors. Connected it back and measured 5700 Ohm (it was colder than 68°F). Started up and it just ran like usual. I did one test drive and all fine. On a second test drive it died again and the problem was back. Since it was up the hill I first thought I might let the bus roll home, but then I thought that the connection was not good. I opened it from the top wiggled und pulled the two sides of the connector, and it ran again. At home I found the crimp connection to the harness not soldered (the other side I did some years earlier) so I tried to solder this side too. Very tricky, so I gave up and pressed that crimp hard with pliers. I hope the connection is now good. [There are still some little problems I can fix later like a vacuum leak at the break booster, but it runs good now.] Thanks again, you four guys giving up inspired me to look very systematic.

This 1978 Microbus or Rabbit bus fuel injection. Once you open the rear compartment door and upper small trunk and it exposed the engine. But It would be sent back to professional bondo body repair and metal bender fender quality fabricator and cut open up more between hole of the floor at atop the rear engine and Using saw saw grind down to the rear trunk hole and slice again so both cut of both side. Then remove the sheet metal between upper compartment hole and engine compartment rear hole. Then you got a rear hood which is bigger then two engine closing doors. But the metal hood will be special order from USA sheet worker and welder shop and a Western Wolfsburg dealership. Microbus is predecessor of Vanagon.

First I'll say that I'm a big fan of your channel and I love you guys. But as a VW FI guy, this was PAINFUL to watch! ;) Carburetor guys always seem to forget everything they know and crack open the AFM first. Please don't do that. Diagnosing the AFM comes LAST. Start out like it's a carbureted van: check valve gap, points, condenser, rotor, coil, spark, timing, and compression first. I hope you did these things. Then go after fuel. You did that by spraying the throttle body and it started. OK let's go from there. The Bosch L-Jet ECU and AFM do not perform a cold start alone. Cold starts involve three additional components: 1. Thermo Time Switch 2. Aux Air Regulator 3. Cold Start Valve (aka the fifth fuel injector on the throttle body). Read the Bentley Book and test those three things. Fuel pressure, more injector testing, vacuum leaks, and the AFM can come later.

The resistive ink on the circuit can be damaged by many types of solvent. And don't grab the rotary arm inside the AFM to turn it. If you push down on the arm you might damage the resistive ink. Go to the intake air flap of the AFM, push on that to rotate the internal arm. Are you a user on TheSamba? I'll connect you with the resident FI repair genius.

I think your fuel pressure regulator might be bad. It's really important to have the proper fuel pressure. When you tested the injector, while they worked, there wasn't very much fuel coming out.

@andrigtmiller 2 жыл бұрын

Part of the reason I think that is that having built Type 1 engines with CB Performance Gen 4 fuel injection, I can tell you when the fuel pressure is off it changes the air fuel ratio a lot. I think the fuel pressure regulator on this old Bosch fuel injection system is vacuum based, and you may have a vacuum leak keeping the fuel pressure low at idle, but getting enough as the RPM goes up, but not enough as it goes down.

Given the way you’re dressed, I’m assuming temperatures in Texas have dropped into the 70’s? 😅

Too bad Carlos Jobe left the VW scene, he was a fuel injection guru. Another person I could contact is Andrew Hollaway, if you want me to, I can call him, see if he would be interested in dropping some info. Tommie: "again, I'm not a professional, but, I play one on KZfaq". BTW, my one attempt with FI, I had a Fastback and I ended up finding out that the FI computers can go bad just from sitting in our hot Texas sun! You guys RAWK!! #VWLIFE !!!

did you check the vacuum hose or you may have bad fuel injectors

@scarrollnz 2 жыл бұрын

Do they run fuel filters? That may be blocked. Also soak the injectors for a few days immersed in injector cleaner if they can take it. Get rid of decades worth of sludge! Good luck guys

Cold start solenoid?

Kinda seems like a fuel pump, it might make good pressure, but is it flowing enough to keep up? Those injectors seemed to have stream of fuel an it should be a nice spray, if there isn’t enough flow they can’t spray

Yes you're right it was the fuel pump!

That L tronic injection is VERY sensitive to dirty grounds.

There is a fuel injector ground on the top middle of the motor.

get a progressive kit for it, Now there is performance parts to hop it up .I think that on has a CW forged crank from factory????

You guys tried alot of things to get it going. But it is a old system, Did you try replacing the computer, or the ignition switch? I tried to read up on the fi chapter in How to keep your VW alive. Three pages in made my brain hurt, and I went with a single progressive weber. Good luck guys. ✌

What is the correct distributor for the bus? I have just inherited my mom's 1976 bus/camper. The engine won't turn over. I replaced the coils and spark plugs. I am thinking it's the distributor, because there is no spark on the plugs.
