Hi, everyone

I have a 92 5.7 TPI engine, it starts instantly when cold , though after about 30 seconds or so it will, start to load up with fuel, sputter then finally die, it will only restart after i hold my foot on the gas to keep it going after this excess fuel clears out it idles perfectly, hot starts are perfect as well, any ideas?? BTW there are no codes, and watching a Diacom scan of the engine idling show nothing, any direction would be helpful , thanks .....GTA

 

Injector leakage, FPR leakage, high fuel pressure, and high MAP may not set any error codes, but could cause your symptoms.

 

Thanks Vader,

The fuel pressure is at 50 PSI vac line off, or 43 PSI on and running, I had some fuel removed "in the prom" at idle and its MUCH better now, thanks. GTA........
