im just finished mounting my AEM fuel rail, fuel pressure regulator and RC engineering 440cc injectors. But the injectors will not pass fuel. They have 12v each, enough fuel in rail. Fuel pressure lies on 46psi. Wich should be optimal.
They also have the right resistance. 12 ohm.

Any suggestions?

I found this. Think it could help. Going to try it tomorrow.

 

are you sure you have ECU signal on injector grounds. the ECU controls grounds of each injector in order to fire injectors. best bet is to install a noid light on injector connector and have someone crank engine while observing light to make sure it blinks. If it does not, may have harness disconnected somewhere or for some reason, ECU not supplying ground to injectors.

does engine start?

if not, how do you plan to perform test that you posted earlier?

BTW that test is for setting base ignition timing of engine, nothing to do with injectors.

 

i testet the injectors with an voltmeter.

The engine does not start.

 

right, you tested the injectors with voltmeter. What I meant is that you now need to test for ground signal from ECU to injectors. not injectors themselves. this is where a noid light would be useful.

Let me know if you need any more help...

 

i also testet the injector plugs.
