Dont even know where to start with a search, tried heat soak and vapor lock, but not coming up with what I need.
LS1, running a walbro 255(I believe) and a corvette filter/regulator, oem gm carbed tank, 3/8" feed line, returnless rail, etc. Turn key engine harness, non feedback.
Has a random no start, only when warm. Time seems to be the only cure.
Injectors pulse, plugs spark, have fuel pressure.
Also developed a random rough idle/bogs under load, and once the pump was whining. Doesnt stall, but wont restart when it has issues.
Cant get a scanner on it without an adapter I guess, but it came to me tonight that the exhaust is pointed at the fuel tank. dual 2-1/2s, and literally directly at the point of the tank that the pickup is. The fuel pump doesnt appear to be getting hot when it happens, and it was refused to restart before with no apparent idle issues(no load, in park)
Could it be that its actually as simple as the exhaust needs the turndowns?
