Trying to help a buddy without investing my life into his car. Just want to get some suggestions.
Here is the scenario, ask any question you have as I may forget the small details to mention.
92 SC 5spd, motor from 91 recently installed, all components transferred.
ccrm replaced to fix cooling fan problem. For a coupel weeks the car stumbled or stalled when he hit a bump.
Tried PCM from other car, nothing changed, replaced ignition switch no change. Tried ignition module, no change. The strange. It has no fuel pressure when the key is on but when you turn the key back it runs the pump for 5 seconds. Could a bad key and tumbler cause this? Suggestions please.
