1992 SC400
New Coil Packs
Replaced ECU
Engine is warm and shut down for about 5 minutes or more. At restart the engine will not maintain idle and dies in park. Takes about 5 times to start and idle properly. If I turn the key on and off for about 3 to 5 times without starting the engine, the engine then starts and idles properly without dying. Does this sound like a fuel residual pressure problem. It starts and idles without any problem when the engine is cold. What's the problem? What can I check if I put a fuel pressure on the system?
