I need help bad. This is a from the other site
http://ef-honda.com/main/viewtopic.php?t=31354
I went to autozone to get a noid light and all the plugs are working fine. I thought it was the injectors so I switched them with a diffrent pair and still the same thing. Nothing. I am getting great spark but no fuel. I tested the fuel injector resistor box that was fine but just be on the safe side I got a diffrent one just test it too. Still no fuel. I have checked all the grounds and cleaned them all. The engine, trans and thermostat grounds. Is there a ground that I over looked?

Is the fuel pump priming?

CRXWOLSKI

Yes the fuel pump is priming and there is fuel getting to the rail and the psi is around 40.

turboZChatch

pop the rail off and spin the dizzy by hand(make sure its grounded) see if the injectors are firing

turboZChatch

You are sure the car is getting spark?

Yeah its getting great spark. I have a second set of injectors that i throw in and they are not work either. I had a noid light hooked up to the injector plugs and they all are working right. Im just out of ???

CRXWOLSKI

I tested the resistor and it was 5 ohms. I went to the junkyard and got a diffrent one. I hooked it up and the same things happen NO start. 8-O I went to autozone to buy a noid light to see if there was anything being sent to the injectors and the noid light said there were working fine. I had a secound set of injectors and I swapped them out. Still no start.
I test the injectors one more time with the noid light. The injectors were not hooked up and the car started for a sec. If I put starter fluid in the throttle body it will fire up with no problems but will not stay running. Im just running out of ideals. :evil:

CRXWOLSKI

anyone?

killa rex

did u check the main relay?

CRXWOLSKI

Yes. i thought that was the problem so I bought a new one and it still does start. Can you have all 4 injectors go bad at once?

killa rex

Not that I know of...

Can u post the specs of your car?

It sounds like you're being very thorough with your testing. About the only suggestion I have is TOO MUCH fuel. I've had that problem tuning standalone in my car before. If it's flooding out, it'll do that.

Yeah that would be great if there was fuel coming from the injectors. The injectors are not firing and the psi is 40psi. But thanks for the ideal.

get a junk yard fuel rail and try it. id eliminate the cheap stuff first

youmayneverknow

by not working, do you mean you pulled the rail off and tried to start the car and see if fuel is being sprayed...

or are saying you checked the wiring, which reads good, and the car won't start...

just because the fuel pump is running doesnt mean that it has the proper amount of fuel pressure to start the car...

sometimes the pressure will be too low to start the car, but if starting fluid is used the car will start and continue to run, maybe poor performance maybe not

or it could not have enough at all, or TOO MUCH

for instance, a s10 truck or blazer/jimmy, needs 63-65 psi of pressure, if its BELOW 57psi it will not start in cold weather unless starting fluid is used.


CHECK FUEL PRESSURE BEFORE AND AFTER REGULATOR IF POSSIBLE

i would check it at the filter first

trust me now, it might say NOOB , but i've been in this field of auto mechanics long enough

CRXWOLSKI

Not to sound like a NOOB but doesnt any read the stuff that is posted?
40 PSI is right. Fuel Pump Works right. Fuel at the fuel rail. Spark from the spark plugs. Throwing no codes. Cleaned and install new grounds.

I did this today and the injectors all fired but they all fired with the dizzy off. I laid the dizzy on the engine and spined it and I got shocked. So I dont know what the means.
