2002 3.0 saturn vue no fuel to cyl. Sign In

I am trying to troubleshoot a 2002 Saturn vue 3.0L v6. 120,000mi, Engine turns over but will not start (does fire when starter fluid is sprayed in intake. I have changed the fuel filter and verified fuel pressure @ filter outlet to be 55PSI. Where do I go from here? (While this question is out I will be attempting to test power to injectors). Any help is much appreciated!

That's not the way that you test fuel pressure. You are testing "dead head" pressure and you need to measure regulated pressure by "T-ing" into the line and monitor the pressure.

You need to test 2 things here

1) Test for injector pulse using a small bulb called a noid light. If none found, check for power supply at one side of the injector with the key on.


2) Use a fuel pressure gauge to test for correct fuel pressure, also noticing if the pressure holds when key is shut off.

OK. I'll get my hands on a fuel test gauge. I was hopeing to test injectors without removing the intake. Is that possible?

If you can access one of the plugs, you can plug a noid light into it. If not you will have to access the wiring before the injector and tap into it to attach your noid light. That doesn't mean to cut the wire open. Do as little damage to the insulation as possible with a very small puncture.

You can't dead the pump on that one unless you plug off the return at the fuel filter because the regulator is part of the fuel sender module. 55 psi is about right for pressure.


Any trouble codes being stored in the engine controller?
Also check to see if the passlock system is activated. If the passlock system is activated, the PCM will disable fuel injection.

A Passlock activation will cause it to start and immediately stall.

Thanks to all for your advice, I have decided to get the car to a mechanic but how would I reset if the pass code were the problem?
Thanks again for all your time.

If that were the case you would have a flashing security signal and the engine would start and stall so it's highly unlikely that it's a Passlock problem.
