So my fuel injectors are not spraying. Nothing.to electrical pulse. I have 32psi at the rail. I changed my main relay twice. I also changed my fuel pump before all this all started. I also cleaned the harness ground,It just started dieing at stoplights and now it just quit running. what could it be I am at a loss.

If you probe one of the fuel injector wires with a meter, does one of them have 12v (or 5v). I forgot which voltage.What makes me laugh about forums, is that no matter how much you try to help someone, they dont take the advice. Go ahead and do it the hard way.
You got to respect what you drive, and appreciate what you have, making the best of what you got. and if that means putting CAI, HID's, a phat stereo system, and a idiot in the drivers seat...then so be it!

He doesn't know squat. If you can't hear the injectors you then got to determine if its the unit or power. What an idiot. If there is no fuel injector pulse, what will a distributor do????
Get his volt meter that he never used, probe the common color for the injectors to see if there is power....let me know how many volts.
It pisses me off when some Guy says they are experts when they just know how to replace parts. They assume what the problem is and waste money on a part that wont fix it. UTI guys (not all of them) are the worst.
If i tell someone to replace a part i make damn sure i confirm the issue.What makes me laugh about forums, is that no matter how much you try to help someone, they dont take the advice. Go ahead and do it the hard way.

check your injector resister box, next to your strut tower bolts on driver side....change that ans see if that helps...also make sure you dont got a short some where in the injector harness,....

your distributor has your cam/crank position sensor in itand thats how it knows when to fire the injectors.He took this tool he uses and plugged a injector in to it and it has a light that should flash and it didn't so that's how I know.I dont have a volt meter. I have changed the resistor box.Isnt it that aluminum box with fins on the drivers shock tower if so I changed itLast edited by thepowderblue; 05-30-2011, 06:02 AM.

Have you tried simply testing the injectors yourself with a 12V source?take them out hook them up to 12V VIA battery they should click if not then they are bad.Ol simple way of testing injectors.Also at prime my CB put out around 40psi, but while cranking it was 45-50psi.32psi seems abit low to me.

Its true. But you will always have a power source going to the injectors. The distributor acts as the switch to turn them off and on. Without the main power source it wont Ark. That's why the next logical easy step was to check voltage and not a distribitorWhat makes me laugh about forums, is that no matter how much you try to help someone, they dont take the advice.

Originally posted by mikecb7LX92 View Posti had the exact same problem, check if your getting power from the injectors to the pins in the ecu. I found out that i was getting power to the injector clips but not to the ecu, so i changed the engine wire harness and bam! that was the problem.

I cleaned the harness ground after it stopped running.Maybe mikecb7LX92 is right that it could be my harness.
I guess I will get into the 21st century and get a multimeter.
Batever are you whoring posts? If you forgot something just go back and edit your post.Last edited by thepowderblue; 05-30-2011, 06:34 PM.
