This is likely a giant shot in the dark, but I thought I would try telling my problems here. I've posted at every other LS1 message board, including LS1tech.com which I was sure would help me out, but to no avail.
The LS1 was running great in the 94 Camaro, until randomly, one day these problems occured. Symptoms: - Car will barely start, most of the time afterfires and shoots flames out the exhaust, but wont start up. Sometimes it will not start after 10 minutes of trying, sometimes it will fire right up. - Tachometer doesn't work (it used to). When you turn they key on, the tach will move up a milimeter from the bottom and sit the entire time. - *FIXED* Speedometer thinks you are moving. When I let the clutch out after starting the engine, with the tranny in neutral, the speedo goes up to 10 mph. If you rev the engine, it goes up thinking you are moving. Things we've tried/checked: - Ground wires on each side of the dash, and by the drivers seat are all good - Main engine ground strap good - Smaller 2 grounds on each side of the engine bay are good - Every fuse inside engine bay and inside cab are good - Unplugged and plugged back in all transmission wiring connectors - Unplugged and plugged back in the 3 front and rear ABS sensors - Unplugged and plugged back in ABS module connector - Installed new crank position sensor - Installed new cam position sensor - Gone through every connector in the entire harness of the car On LS1tech and everywhere else I received lame responses like (you've got your speedo plugged into your tach!) I don't know anyone else who has transplanted an entire drivetrain into another car and used the stock wiring harness. Seems like most transplants end up with a Painless harness or something else. At any rate, the blasted car is ready to run... if it would just run. Everything else on the car is ready to let it move and drive! /Cries for help |
