ECU question

[BrokeTurbo]

Ok, Ive been batteling a fuel injection problem, with the number 3 injector not getting a pulse from the electrical side. I've taken the ECU out of the car, and off the harnesses, and inspected both the harness at the ecu, and at the injector. Both look fine. I also opened up the ECU, and nothing is looking bad. I've heard of problems with compasitors leaking, but I guess Im fine, beucase nothings on anything. All is clean.

Where should I go from here?

I was thinking about putting the ECU back in, take a little bit of rubber of the light green wire right where the harness connects into the ECu, and seeing if it has voltage. If it does, I must have a cut line between there and the injector. I will also recheck the voltage at the injector harness. I will also get that small light (Noid) i beleive and see what that does too.

Anyone have any ideas let me know. Thanks

Well the Noid light wont help much if you have no power at the connector. All that does is flash when it sees a signal that would normally fire the injector. Try measuring the resistance again at the connector. If that doesnt work, bust out the wiring diagrams and trace it. You said its only #3 so it cant be anything else....good luck
