Need help, K5\'er stranded in Victorville with a EFI problem Chris Raffo (retroblazer) is stuck in Victorville CA right now trying to find out why his '94-ish sub (TBI 383) won't run. He's supposed to be in chicago for turkey tomorrow, so this is obviously pretty bad. Anyone know how to find Jason "zcarczar"? He's in Apple Valley near there and might be of some help in some way. Otherwise, the problem is the timing keeps advancing and retarding by itself, surging. They replaced the map sensor, O2 sensor, verified correct operation of the fuel pressure regulator and pressure level and checked the ECM by replacing it with a new one. There may be more that they've tried but that's what I know. Also, it's not throwing any codes. Any ideas? Anyone in the area have a TBI chip that would run it without the distributor or know if he could delete the dist. and run a manual version without wigging out the ecm? Thanks for any help. This situation sucks.
