91 camaro RS 305 TBI, I have fuel presure, new fuel pump, noid light flashes once when I turn crank the starter. I checked voltage at injector terminal. I only get 1 volt reading and I also had the ICM checked and it is OK. I can start it by using starting fuild and can keep it running a few moments by pumping the accelerator and then stalls out. Any help would be greatly appreicated.

Important to know if it's not working at all, or if it is working some, just not enough? If not at all, then you need to check the injector wiring circuit, it's pretty simple really, just a hot wire with key on, and a ground wire that goes into the engine computer. Test with a voltmeter, best practice.

You should probably first check fuel pressure. The injector won't work unless the fuel pressure inside it is at the specified pressure. If the fuel pressure is too low, you have a bad fuel pump or a clogged fuel filter. If the fuel pressure is correct, you could have a clogged injector. The best way to clean that is with the injector off the engine.

FIRST STEP WOULD BE TO SEE IF YOU HAVE INJECTOR PULSE

you have a TBI 8valve engine. just like my 91
the injector , not firing, so by guy method.
1: it dont click? (sonic ,stethoscope)
2: the noid dont flash. (use a noid lamp and win)
3: it dont squirte, watching it with eyes, cranking,

if the noid fails, that means ECU is bad or one of 3 inputs to ECU are dead.
if noid works, that means, the injector is cogged, it has 10 micron screens that are easy to clean. or there is no 35 PSI fuel pressure.

here is the page just for that.

1. THE ECU IS PROGRAMMED to cut fuel if there is no spark preventing TV like crashes and burns. (and other fire reasons)
2. the tests are all easy. no order but #1 is #1
3. fuel pressure at spec.
4. injector coil reads 1.0 OHMS.
5. injector clean. (there is only one, so all hope is just here)
6. noid lamp fails , so is CMP dead? or TPS TP pin stuck high or , ecu throwing code 41./42s errors, BINGO!

check fuel pressure TBI injection fuel pressure should be 9 - 13 psi.make sure fuel pressure above 10 psi because throttle body need at least 10 psi. in order to work right.if all is good check see if PCM firing the fuel injectors.go to auto parts store buy noid light.to use noid light you have to disconnect fuel injector electrical connector then plug noid light into fuel injector connector.crank engine watch noid light should blink meaning PCM is firing fuel injectors if noid light steady not blinking PCM not working.if noid light dont light up you have open circuit in the fuel injectors wiring.if check engine light flashing have vechicle code scan.bad tps sensor will also cause problem you are having.

Check fuel filter if ok check fuel pump pressure and supply/ approx. 1 liter in 30 sec.

I assume you are not getting fuel spray from the injectors ?
If you are getting voltage to the injectors you should be able to ground and get a spray. If no spray, they may be stopped up from sitting.

simple the computer signals the injecters with negetive voltage approx.3 volts

NEEDS A TUNE UP

You need to run move diagnostics. You are getting fuel up to the injectors but are the injectors spraying.
How do you know that your pump is fine? It might be running but is it building up the right amount of pressure? What is it at? If it is below 33psi then you may need a new pump or possibly a fuel pressure regulator.
If it passes then you will need to test the injectors. You can go to the part store and buy a repair manual and a special key that allows you to retrieve the codes that are stored. If you write back with the code numbers I can give you the definitions. Good luck.

sounds like ecm. car starts but when it switches over to run setting from cranking setting the cumputer ecu doent activate the run curcuits which may control your fuel injectors. check to see if engine has spark. remove one plug wire from spark plug put it close to the valve cover if you see an arc then you know that you have spark. then also go to fuel pump in tank and check voltage on the power wire if you have good voltage and the pump doesnt make any noise while ur cranking then it may be a fuel pump if the pump is making way to much noise then check the fuel pressure by hooking up a fuel pressure gauge. all test are to be done while someone cranks the engine. noid light for the injectors, disconnect on injector electical connetor connect the noid light to the wire that u just unplugged from the injector. the light will flash while u crank , once it goes to the run circut the light will either stay on which will shut off ur car or the light will stay off which will do the same. if the noid light did what I said when it went to the run circut then it is what controls your injectors...ecm good luck....daniel
