No fuel/not firing

sugarfree · 03-16-2009, 04:07 AM

Were having a problem starting the motor. First it was the temp gauge problem that was brought a while back, but that problem is fixed.

The problem now is it seems as the injectors arent working. We can crank it, but it wont catch. We sprayed carb fluid in the mainfold to make sure we got spark and the motor turned on. We took out the spark plugs and we smell no fuel. What else could be the problem?

We are going to try the EFI relay, but other than that what could the problem be?

No engine codes either.

How long has the car been sitting?
After a while gasoline starts to gel up and you'll have to drain it and put some new fresh gas in there

Have you gotten a fuel pressure reading? Possibly a bad pump.

We checked the fuel pump and gas is coming out of it. Just the injectors are not turning on for some reason. We also hear the pump turn on.

The motor had been sitting for a really long time, over 3 years.

but are you getting fuel pressure at the rail?

I am almost sure that the needle is fixed in the injector. you can try to put with a wire by ticking on the accu pole for A SHORT Time 12 volts on the injector. But the best solution is to let them clean in a ultrasone bath.

"accu" LOL, je mag ook heus wel batterij of battery zeggen hoor!

ultrasound bij de weg.

Have your injectors cleaned out, possibly swap out for new ones if they are stuck-ish real bad.

Make sure you have current running to the "Head", remove an injector plug and ground it with a volt meter with key at ign-on, should read something
