Just rebuilt the engine in my 02 gp gt. Have 300 miles on it plus about 5 hours idle time. First start of the day or when motors cold it starts fine. After i shut it off then try to restart itll crank for a few seconds start then immediately stall. I have to give it gas for a few seconds to keep it running but when its running it runs fine.. No pending engine codes. New plugs, wires. Fuel pressure is 55psi koeo, about 52psi running then jumps up to about 61 when vac line unplugged. Psi is about 58 when cranking.
Any one have any ideas
