I replaced distributor and ecm. I checked the pickups in the distributor. The coil. The cap and rotor. Now i replaced the ecm with the same ecm number except at the end of the number on tyue ecm it had a d. The distributor on the car that the d ecm had a different type pickup. I dont think the original ecm is bad. I can crank engine. As soon as you move key from cranking to just on i get one spark. Thats with the original ecm. I have checked fuse. Even put jumper cable to make sure voltage was high enough. I bet its some simple thing i have overlooked. Help or i might have to start it with a match.
