i got spark, but i can't get juice to the inj.? i checked the fuses ,they're ok .i used a test light at injector wires and nothing.like i say it's got plenty of spark.i mean its firing.i hooked 12v directly to pump and it ran.

 

The pink wires on the injectors should have 12 volts with the key on. When you say you hooked 12v to the pump and it ran do you mean the engine ran or the fuel pump ran?

 

the pump.

 

The positive side of the injectors should be constand +12v with the ignition on. Check that they do at the plug with the test light between the wire and a chassis ground.. The ecm grounds the other side to fire the injectors. If you put the light across the injector terminals, and they don't flas but have power, the ECM driver is bad or the wire is broken somewhere.

 

everything works on my car,but the injects .i've tried a different ecm and the same thing ,power evrywhere but the injectors. does the f/p relay have anything to do the injectors?

 

indirect i suppose. hard for injectors to spray gas if the pump doesn't get it to em.

 

never mind ,it won't even turn over now-AGAIN!

 

No, not never mind. That problem is still there. Trace back the power from the injectors back into the fuse block. There must be a break somewhere if everything else has power. Did you check the fuses?

 

i checked fuses ,the car turns over good now.but still no juice to the injectors.
