97 Lumina 3.1 No Spark
Hello. Having some problems with my 97 Lumina with the 3.1 v6. Theres no spark. So far i have replaced the crankshaft position sensor and ignition control module with no luck. There is 12v getting to the icm. I also repaired the ckp sensor harness and checked to make sure it has no resistance. Coil packs are tested and good and have done a compression test and got 150psi on all cylinders. Im running out of ideas. Thinking maybe its the ECU?

Try the pcm first. I've replaced my ecm twice since I've owned. Is there any sel light/code? I had issue with my 96 just dieing, would show PO102 maf off performance, that was due to the ecm shutting off the engine. Would not restart until i erased the code. It might run two weeks, or two hours. Look at ebay for an ecm if need be. I bought the last one, no core with (sent the guy the vin) programmed for $70

Just to confirm pcm=ecm right? Not 2 separate ones? Do you remember where you got the one for $70? Did it need additional programming once on the vehicle? Also there's no check engine lights.
