After changing a head gasket, I went to fire up and noticed three injectors are leaking where they meet the fuel rail. They weren't leaking before tearing everything apart and nothing was done to the rail other than moving it. From what I've searched, it sounds like O-rings. 2002 2.0 Jetta.
View 3 RepliesI have an 86 F150 that is idling rough. It used to cut out on me until I replaced the fuel pressure regulator. I have read in other posts that the problem for my rough idle could be leaking injectors. When I replaced the regulator I found a bad injector. My question is that if I check my fuel pressure, with the new regulator, would the only way I would lose pressure be that my injectors are leaking?
View 5 RepliesI had my r on dyno today to see same numbers, but injectors or cutting off at 15psi.. and runs lean at high rpms. I think 550cc injectors go up to 18psi??
View 6 Replies2005 Jetta 2.0L Bev gas engine... Changed fuel pump. and then not getting power to injectors. Changed Battery, fuse block at battery, repaired alternator wire, and changed ignition switch. Tried napa fuel relay and no change. Put old relay in and car started up but died several times. when it shuts off I'm losing power to #32 and 34 fuses. when cycling ignition, power restores at times and car will run. By the way fuel pump has always run since changed. Codes show injector circuit malfunction on all 4 injectors P0201, P0202, P0203, and P0204.
View 1 RepliesI have a 1989 GMC suburban V8 350 5.7l that will not start. I have replace the following fuel pump and sending unit, fuel pump relay, ECM computer brand new, new fuel filter. When I go to start it the fuel injectors dont spray fuel into the combustion chambers verified fuel injectors still work by bypassing them and they spray fuel. Fuse's are not blown. I have been told the oil pressure switch might be bad but I'm at my end of sanity on this.
Additional Details : Tried spraying fuel into the throttle body and still no fire, ignition module and ignition coil where replaced 15,000miles ago.
I've got a 01 f150 yesterday stopped running (like it ran out of gas). Has half a tank. Fuel pressure at rails good but truck will not turn over. Fuel pump and filter less than year old.
View 1 RepliesI took my 2008 Prius to Jiffy Lube to have oil changed. When driving away, I made it about one block and all warning lights came on: Master Warning, Hybrid System Warning, Brake System Warning, Malfunction, etc. I pulled the car over and stopped. I started the car again, lights still there - drove 2 blocks back to Jiffy Lube and lost momentum about one block away, with pedal to floor, I could drive about 5 miles an hour into the bay. They looked at it for about 30 minutes and claimed I had bird seed that dropped under the air filter.... I said "goodbye" called AAA and had it towed to my dealer. They said it was because air had entered the system due to my being low on fuel. I have never heard of being low on fuel and it causing the car to shut down nor did I ever get a warning of low gas, still on one bar. Each time I restarted the car at Jiffy Lube, it started fine, drove forward or backward, then lost momentum again. Still no warning of being out of gas. The ticket from the dealer states:
"Vehicle low on fuel causing ECU to shut down fuel injectors when engine started to misfire. Found codes P0A0F, P3190 in system. Added 5 gallons of fuel and reset ECU."
I have replaced all the injector seals as well as the ball cup seals but when I crank the truck over after a few cranks I see oil bubbling up from the top of all the injectors. When looking at the injectors from the "top" side all looks well but when I use an inspection cam from down below I can see this happening. Any thoughts?
View 9 RepliesI have a 2004 Ford F-250 6.0 power stroke, the previous owner got water in the tank, rusted the injectors, and destroyed the pump, I changed the pump and 2 injectors, it still died. It has 300K miles on, pretty high. Right now all symptom is the motor is starving for fuel, because the injectors are leaking, getting air in it. When I pull the fuel filter out, it is full of dirt, And swollen up because of water. So, I am planning to flush the tank, get rid of the water and then replace the injectors. Could there be any damage on the motor ? Engine problems? I know 6.0 is a bad design, but apart from getting rid of it, how could I fix ?
View 3 RepliesI recently had my fuel pump replaced in my 2005 GTI ... twice. Both times, the fuel gauge no longer shows a full tank, and doesn't show empty tank correctly. Is there some way to reset the gauge? Is the pump somehow tied to the gauge, or did the mechanics mess the float up when they changed the pump? Sadly I had it repaired somewhere other then the dealer.
View 1 RepliesMy 2010 Acadia with ~53K miles had a fuel injector go bad. $1,200+ repair bill. I was told by the dealer service agent that when an injector goes bad it usually means it had an open circuit, and that is what happened to mine. Is there a known problem with the injectors? I have 5 more that could potentially fail and I am trying to determine the likelyhood this might happen again.

No fuel to injectors, I have replaced pump, strainer and filters. Changed the filter first and ran fine with a few misses (likely no fuel?) then just got the new pump and strainer on today. Again drove fine with a few misses. Got down to the river to fish and went to leave and once again no fuel to injectors, sniffed the vacuum hose and it had no gas smell.
I have honda civic 2005 with 170,000 miles on. My car has been little shaky with cold start in the morning and Engine light finally on. I was told that I need new fuel injectors from local mechanics. I'm a poor student so I decided to fix it myself. I was able to reach down to fuel rail and It was very challenging to take the rail & injectors out. After I finally pop them out with long driver/hammer, It is even harder to put new ones inside, all the way in. I tried put some oil at the end but still did not completely go in. Is there any special tool I need to use to put them in? I tried oils...ect.
View 9 RepliesA little background, daughter came home one day with a blown plenum gasket. Car sat untouched for a number of months before I got around to replacing the gasket. After the fix I have a no start condition.
I have been able to chase the problem to no signal to the fuel injectors. I had a momentary (1-2 secs) good noid light once but no light now. Good pump, filter, pressure at the rail, crank sensor, CMP, gas etc. I have also tried a new ECM but to no avail.
Codes I was able to pull were 111, 114, 116 and 327. All pretty much reflect things outside of the main problem such as low coolant temp and the like.
I think it is a ground in the injectors circuit but not sure. Also, how to proceed about checking the ground in the injectors circuit?
My Jetta is leaking gas like a sieve when the fuel pump starts. Its pretty obvious where its coming from. What this part is called or if there is more to it than just replacing it. Its coming from the round looking part on the fuel rail. Let me know what you think.

My '10 Golf TDI started leaking gasoline this morning, found smallish puddle in the garage. Looked underneath and there was definitely fuel on the underside of the tank. Moved the car into the driveway so the leaking fuel can evaporate.
Not sure what happened. I did hit something on the highway yesterday, a piece of tire from a semi went underneath the car. Of course it's been really hot 100+ deg lately. Maybe a fitting has come loose?
I'm not going to risk driving it, but can't do anything about it until monday. I'll call the shop and see what they recommend, tow or drive.
I took my fuel pressure regulator off hoping it would get to my green top coolant temp sensor. It doesn't Now when I put it back on its leaking? I didn't depressurize the fuel line first. Can this be the cause? If so do I just open the gas cap, pull the fuse for the fuel pump, and then re-insert the fuel pressure regulator? or do I need to get new O-rings for the regulator?
View 10 RepliesI was curious as to how ambitious a project this would be and if special tools are needed.
View 1 RepliesI just was given this truck the fuel pump was wired directly to the battery I ran new wire to a new relay to fuel pump using a toggle switch to turn the pump on. Now I'm getting no power to the fuel injectors does the pump relay also send power to the injectors.
View 7 RepliesI have a f53 motorhome and 4 out of the 8 injectors pulse. The front 2 and the back 2 don't pulse. The middle 2 on both sides work perfect. Why would they not pulse and only give out positive on the two wires to the injector on the one that don't work. The ones that work they pulse.
View 8 RepliesI have a APR stage 2 chip that should normally be pushing 17psi. But today I noticed it has dropped to only about 15 psi at 3k rpm and at about 4.5k rpm it drops to about 10 psi. I also then noticed my oil filter was covered in oil and it was not leaking oil before today. I have a stock K03s turbo and I am really lost on what the problem could be. I want to check for boost leaks sometime this week, but I'm curious as to what else it could be.
