Gmc - Sierra1500 :: 1989 V8 Will Not Start / Fuel Injectors Don't Spray Fuel Into Combustion Chambers
I 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 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."
Golf IV R32 :: Injectors Go Up To 15 Psi - Need More Fuel?
I 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??

I just purchased a 2011 GMC Acadia about 2 months ago. Tonight it was raining and 37 degrees. All the windows were fogged up when I started the car. I put the climate system on defrost but as the manual states the A/C did not go on because it was below 40 degrees. It took over 5 minutes to defrost the windshield. The rest of the windows were still fogged up. As I drove off the car had a very difficult time keeping the windows clear on such a wet and humid night. Early that night it was 40 degree. When I turned the defrost on then the A/C went on and all the windows in the car were clear in 10 seconds. None of the foreign cars I have owed shut the A/C off like this. I also don't recall any of my dad's old GM cars doing this as well. Do all GM cars do this now and why?

92 GMC C1500 V6
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.
Civic - Honda :: 2005 - How To Put In New Fuel Injectors
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.

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.

A 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?

I 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.

I 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.

I recently bought a 94 Ford Ranger XL 2.3L. This is a Mazda engine built for Ford. There was a slight ticking noise from the engine. Two months later it has became worse and louder. I bought a mechanic stethoscope and found the noise was coming from two or more of the fuel injectors. New plugs and wires, fuel filter, air filter was done when I bought it. Cleaner has been added to the gas a few times now. I am about to replace the belts and hoses, Bosch platinum plugs and fuel injector O-Rings. I just don't know if it will be enough.

When the car is cold & first started, the high pitch noise by the fuel injectors is the loudest. When it warms up the noise is reduced quit a bit.
I thought maybe the fuel injector O-rings are bad, but the car idles and runs fine ( no error codes). Maybe the intake manifold gasket, but the car idles and runs fine. It is a weird noise.
Accent LC (2000-05) :: 2002 - No Power To Fuel Pump Or Injectors
2002 accent with 70k on it the 1.6L
Here is the problem, the car sat for two years and when getting her back to life it would start so i started testing everything i could find. here what I get
Gets spark
Power to the cam and crank sensor.
All fuses and relays are good.
Found out the ecm was not grounding the engine control relay to turn on the pump and injectors so i added my own ground to the grey/orange wire and the pump turned and and it fired right up.?
so my question is what does the ecu look for to turn on this relay?
It was fine for a few days but now even with the relay grounded (activated) the car doesn't start . but let it sit and try again in ten mins and it will start every other time I come home from work and try....but i do still get power to the pump and injectors.? There might be a electrical monster in this car but I don't know what else to check.
I have another accent same year so I switch the ecu and every relay i could find over from the run ing car and i still have this problem, also changed the cam and crank sensor, so I am at a dead stop.
Prius (2004-09) :: Code P0302 - Fuel Injectors Leak
My prius is almost mint, with 226k on it. I just recently got a code from it P0302, so I thought I'd check the fuel injectors, I took them out and cannot reinstall them without them leaking all over.. I removed and replaced new orings on the top and cranked down the bolts really hard and still a bunch leaking. Is there a trick I should know about?

View 3 RepliesFord Wiring/Electrical :: 1997 - Fuel Injectors Not Working?
I swapped a 4.9l into a 1997 F-350 that had a 5.8L originally, my issue is the fuel injectors are not working. I did my homework and got the harness that was with the engine out of a 1995 F-150 and also got the correct PCM to go along with my E4OD tranny that is in the F-350. It has spark and 60 plus PSI fuel pressure in the rail and will run with starting fluid shot in the throttle body. Both vehicles came with OBD I so should be compatible there. I do not have 12v to the injectors and obviously the NOID light shows no pulse either. Could be a ground but not sure where to look or what else could cause this.

97 F150 4x4 XLT 5.4L... I had two cylinders misfiring, removed COP, injectors and plugs. Reinstalled all parts and reconnected all sensors. Now I am not getting fuel to the injectors. Double checked for disconnected wires and hoses, checked all fuses and relays, also the inertia switch. Fuel pump does not hum when key turned on. Tried hitting bottom of gas tank. My question is, before I pull the tank again, is there something under the hood I may be missing. It does get quite crowded at the rear of the motor.
