**MUST READ**
Hi guys here's a DIY guide on how to completely disassemble & clean your Delphi injectors if they're clogged or if you simply want to add this method in your routine maintenance. We recommend cleaning the nozzles every 100,000kms and while you're at it, replace the injector copper washers with new ones as well. It's also best to clean the injector seats on the cylinder head before you put the injectors back in. There are injector seat cutter tools which you can purchase online.
Remember: This is not a certain fix on faulty injectors. If your injector is stuck open / closed, doesn't fire or actuate when energized, excessive back leakage, It's best to consult a professional.

Many thanks from Brazil bro!!! After being played the fool in +- $400 I got sick and decided to give it a shot...the car doesn't "smoke" anymore and I feel so good about it. I haven't got the ultrasonic cleaner but let them immersed in wd40 for the night and they are awesome now...cheers !!!

How do you take out the solenoid? Just force it out at the gold-plated contacts? I wonder why the Factory forbids the use of ultrasonic cleaners, i was readingthat in the manual.

Hello, I put a new Delphi nozzle and return valve kit on my injectors. I assembled it exactly like in your video. My car started after a few attempts, the car is running well, accelerating normally and getting good fuel consumption. But I hear a noise around 2,000 rpm like a frufrufru... I didn't do the diesel return test to see if any injectors are failing. Do you know what the problem could be? Thanks And happy new year!

@btdgarage 6 ай бұрын

Hi! Some noise is normal for the first few kilometers due to air that got in the system. However, if you’re way past 100km and there’s still some injector noise, try retightening the injector clamps to spec and make sure the injectors are seated properly

The first time I assembled these injectors, I assembled them with a kit from Aliexpress. Lasted 30 thousand km. this time I used the original Delphi kits. I did all the tightening with the torque wrench at 60nm. Yes, for the first 30/40 km there was a loud crack, crack, crack, and then they went silent. I'm just going to do the return test to see if they're all balanced and then I'll try to re-tighten them. Then I come here to tell you what I discovered. Thanks

Hallo, please your answer - what minimum power of ultrasound in Watts and power of heating in Watts must an ultrasonic cleaner have to reliably clean the injection valves, nozzles ? What was your cleaning solution and what temperature you set for cleaning ? Thank you for your answer in advance.

@btdgarage Жыл бұрын

Hi! These delphi injectors require a fuel rail pressure reading of around 4200psi and up when cranking before the ECU will energize the injectors to start. Best to bleed the fuel lines first with the injector plugs disconnected until you get a decent amount of cranking rail pressure (use a scanner with live data stream) before cranking it with the injector plugs connected. Also, starting these injectors without bleeding them thoroughly often results in air lock

@demonautomotive2726 Жыл бұрын

Just suck on the return line for a minute with a vacuum pump, you can find points on the high pressure fuel pump or on the filter (and block off the other hole if you hear air being sucked in again). I have been using one from Sealey that works on my air compresser for +10 years. Still sucks like a champion. :)

@demonautomotive2726 Жыл бұрын

And on some cars you'll need to turn the ignition on so it's best to do that as wel. But listen carefully, because some also have electrical fuel pumps in the tank, that you don't get sprayed when taking of a fuel hose. If you have one like that just cycle the iginition on/off for 10-20 times. Some can be a real pain in the ass to get started, been there done that. But a good suck on the return line always does the trick.

How do you remove the large pin on the second part of the disassemble , I notice you you used some king of force to assemble it , can you explain how to remove it ?

@btdgarage 2 жыл бұрын

Hi Josh, you have to push the other end up (where the connector goes) with a flat head screw driver but be careful not to bend the pins. There’s two pins on that end but pushing just the longer one straight up is enough. Just keep the screw driver horizontally flat. It’ll have some resistance since the solenoid end has a rubber O-ring on it but It’ll go with a few push. Check 1:29 (bottom end)
