So I pulled the car out after winter storage today and fired it up. It runs like its missing on a cylinder and lean.

Pulled a plug on each cylinder and noticed it didn't make much difference in how the engine ran if I pulled the #2 plug wire. After confirming sprak was present I used a mechanics stethoscope on all the injectors. The #2 does sound like it's clicking, but it is more faint than the others, and seems intermittent at times. So I pulled out the noid tester lights. All the other injectors would pulse the noid light. If I reved the engien slightly the light would get brighter/faster etc. The #2 cylinder would not illuminate the noid at all, even at a slight rev.

I am getting 12v and ground to the injector connector. I rang out the c15 pin on the ecm (#6 inj) and I have continuity between that pin and the #2 injector plug.

I don't know of anything else I could check? Can one injector driver fail? Any other ideas?

Thanks All!
 
I got your PM. If the ECM is basically alive, but has one cylinder not firing, I can most likely fix it.

I will PM you an address to send it to.
