No Fuel!

Ok so i hooked up everything right with my new intake.
But the injectors wont let out any fuel.
Fuelpressure is good. Spark too. Wires, Dist. Cap/Rotor are new.

Does someone know, what that could be?

Thanks,
Nebu

Is your fuel pump working. What pressure did you test it at? Have you checked your inejctor fuses?

fuelpump works. pressure should be ok too. havent checked the fuses yet.

but... when the ignition is on, there are 20mv at the injector cables. and it stays around 20mv even when i try to start...

i have replaced the original injectors with the 350 inj. but they are ok afaik.

Got some news.... Connected the Laptop to the ECM today. I get no Errorcodes and all is fine, but.... when i try to start the motor, the RPM signal stays at "0". I think that will be the problem.

Where does the ECM gets it RPM signal from? Maybe the connecters are oxidized....

I've logged the startattempt. click here
