HELP! fuel system problem and no one knows whats wrong
new fuel pump
new fuel filter
cleaned the injectors and fuel lines ect ect
dropped gas tank, sent to radiator shop to have coated (was BAD!)
checked all the wiring, getting perfect voltage to pump.
turn car on, runs and idles. heats up to about 189-191 and then the fuel pressure starts dropping off, and the car dies. i can turn the car back on it will run for about 2 seconds and then start dying even if i pump the gas.
and im still getting 13.75 volts to the fuel pump while this is going on.
could it be vapor locking? and also the vaccum lines going to the fuel pressure regulator are peachy.
car is megasquirted.

love the braaaap
Check your FPR. It could be malfunctioning when the car get hot. Other than that, mabey check your fuel maps in the megasqirt to see what your regular run settings are. Mabey your running it too rich when it goes off the cold running mode.
