Thanks for the great info! I have a injector wiring issue on my 2007 jeep wrangler. I have a cylinder #4 misfire. Its reading 14.0 -14.1 only on #4 cylinder. 1,2 3,5 and 6 injectors read 13.6 -13.8 and never reach 14.0. Where could my problem be?

Thanks I just found out what the problem was thanks to your video on crankshaft sensor. I was getting no spark on ignition coil pack but did have voltage on the connector. So checked voltage on the fuel injector with a light probe. The control side was no lighting the probe when I cranked the engine. So I checked the crankshaft sensor by the harmonic balancer. As I was checking the connection, I noticed the teeth weren't underneath the crankshaft sensor and the belt seemed off. After further inspecting the harmonic balancer I notice it was coming out which got the teeth to not be underneath the crankshaft sensor. The bolt holding the harmonic balancer had broken off and balancer was coming off.

I've always been a nut and bolt kinda guy and would GLADLY pay for anything electrical. I had a p0304 on a GMC Sierra 1500 5.3L so changed injectors then had a connector clip break and replaced it. Only to have it followed by a p0300 random miss. Compression is good but thought there maybe an issue with the way I spliced the connector. Wasnt 100% sure how to test the connector so I found you. Thanks for this so I know how to properly test the wiring. I WAS just gonna unplug it to see if there was a change in the boggy/rough idle or not to tell me if I spliced incorrectly but this is a true way to test. So thank you again for this video friend!

Paul, thanks for showing that, it is good info. Perhaps you should have explained how the injector circuits work, as i think that not many do understand. I'm a Chrysler dealer tech, and the way Chrysler designed their systems, the injectors get 12v all the time, the pcm turns the ground on/off to turn the injectors on/off. I don't know atm how all the other manufacturers design their injector circuits, but wanted to point that out in the event that there are different designs.

Awesome instructional video, thank you for making it and sharing it. I had just completed the dreaded plenum plate and gasket repair on a Dodge 5.2, along with numerous other repairs and replacements while in there. I had one cracked fuel injector, so I bought a new one to replace it. It was a BWD (Borg Warner). Got everything put back together, and it was running like complete shit, bad idle, wanting do die, missing, etc. The computer finally kicked a code, P0208, which was the same cylinder that had the brand new injector. Found this video doing research, planning for the worst, even a possible broken valve spring. Well I checked the resistance on that injector, and there was none. Brand new, non working injector. Just replaced it and my truck is running the best it has since I've owned it! Lesson to be learned, don't ever count on brand new parts to be in working condition! Anyways, thanks again for the video!

Turn the ignition off. Disconnect the Fuel Injector harness connector. Remove the ASD Relay from the IPM. Turn the ignition on. Jumper the Fused B+ circuit and the ASD Relay Output circuit in the IPM. Using a 12-volt test light connected to ground, probe the (K342) ASD Relay Output circuit. Does the test light illuminate brightly? Yes➡️➡️➡️ Go To 4 No ➡️➡️➡️ Repair the open in the (K342) ASD Relay Output circuit. Perform POWERTRAIN VERIFICATION TEST VER-5.

If the plastic of the wires going to the injector plug is cracked open but not touching each other or the ground(Body of engine) could this still cause a small misfire during a cold idle? When I say small misfire I mean a misfire that does not register on the ECU of vehicle just like a slight stumble as if an injector gave too much or too little fuel.

To find an open or a short in a wire, Power Probe's circuit tracer works well. It is unique in that it switches from tracing E field (voltage, open wire) or H field (current, loaded or shorted wire) as needed and LED even indicate direction of current flow. No, I don't work for PP, I'm just a satisfied customer.

Just a note. If you were doing this on a Chrysler product with an ASD relay, you would only get power feed to the injector when the computer receives a crank signal. I suppose if you were working alone, the workaround would be to replace the ASD relay with a uActivate and activate that circuit using that tool.

This was suggested to me. Not sure why? Simple think out side of box. Noid lights in my opinion are a waste of money. Just use a bulb. For example the common 168, 194, or 912. Bend the contacts down. The wire is small enough that it makes it difficult to damage a connector from front probe also small enough to back probe. If you broke or lost your homemade noid light. It is not expensive to make another. What's the cost of a 2 back of 168 bulbs in your area? Simple circuit diagnostics is where the break down begins at many shops. At least the customer got a second opinion which I always recommend if it doesn't seem right. More importantly a perfectly good module was not replaced. Keep teaching and preaching test before you put a part on!!!

The VQ35de engine has the injectors hidden under the plenum. So it's gonna be difficult to run this test. I'm just gonna throw a $185 wiring harness on it and hope for the best.

Mnnnp. Never thought about using my noid lights for injector pulses! Another great video!!!!
2007 Jeep Liberty, 3.7L. Have code faults for #1 misfire, fuel injector 1 circuit open, and Bank #1 lean. There is a slight rough idle, but no misfire perceived, and it runs fine under load and high speed. Doesn't burn oil. Gets 15mpg combined mileage. Ran fine when I got it 64,000 miles. Now it has 110,000 miles. It has had this issue for about 10,000 miles. Not getting worse, but so far plugs and coils and cleaning intake hasn't corrected it. I checked and cleaned Injector and Coils wiring connections and they look good too. #1 Injector plug had some oil in it, somehow. Cleaned it very well with first brake cleaner, then electronics cleaner. Let it dry and reassembled. Can bad Injector o-ring cause this? I already ruled out spark plug, coils, valves, and did intake cleaning. I have not checked orings and the wiring from #1 Injector to the computer control. And don't really know how to. Any tips on checking Injector and its wiring and control while it's still in the head? Thanks!

I have a 01 Mercury Grand Marquis I changed my gear selector and they ran before that but now I'm not getting power to the injectors so they can start

Is it also possible to do a 'continuity check' between injector control wire pin and the ecu pin using multi-meter?Ain't the same thing?Great videos man!

Also if in this situation we HAD 12v at injector and 12v at the computer this means that the harness is good and injector is good AND THE ONLY thing left is the ECU which is not grounding the circuit(engine running) then the injector needs to spray fuel, am i right?

you could do that, but the more you watch me, the more you'll see how much I hate the ohmmeter and why

This one had an open wire, not a faulty computer. Also, if you find a computer that is not pulsing the injector, it may be doing so to protect the converter from a misfire, so there are other variables.
