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.

 

can you datalog the cold start until it dies? That'll help determine if it's the MS or mechanical
