When the engine is running is the CEL on solid? When you turn the key on, before starting it, does the CEL come on, flash off once and then stay on until started or does it just come on and stay on? Are you positive that's the service number?įrom your description of how the engine is running, it sounds like it is in Limp Home Mode (LHM). Six_Shooter wrote:That PCM is for a mid '90s TBI truck.

With no data or connectivity between ALDL and scanner, data logger or emulator I'm basically dead in my tracks.Ĭan you recommend anything that can help me with these problems? Wires seemingly go to the correct pins on the computer but again no data.Įngine starts but doesn't run well hi rev idle, to hot, etc. Scanner says not connected and to check ALDL link. I plug in a OBD1 scanner and I get no data. I also purchased Moates data logger, Burn 2, and Ostrich emulator, I also have the two items pictured on your web site (the green thing and the memcal).

I bought a custom wire harness from a now nonexistent company called (CustomEFI). I bought a doner car for the TPI system which was a 1987 IROC Camaro Z. I built a 1990 Jeep Wrangler YJ with a 5.7L Chevy engine.
