Removing power to main fuel pump solves hot start.....WHY?

List of work done is as follows; new intake manifold gasket, new plugs, new plug wires, new injector seals, cleaned throttle body, O2 sensor seems to be working, junkyard injectors(16), junkyard LH Jetronic computer, junkyard coil(3), junkyard distributor(3), ECT(2), junkyard fuel injector relay(6), junkyard distributor(4), junkyard cap and rotor(5), junkyard IAC(3)-I don't trust any of them 100%, junkyard air mass meter(4), junkyard fuel pressure regulator(5).

I have swapped all these things out in EVERY conceivable combination. One problem persists. If I start the car and let it run for as little as 15 seconds, it will not restart. However, if I remove the #1 fuse it will start perfectly then I have to hurry and put the fuse back in or it will die.

I have read ALL of the ringlee files. I know what is happening when I remove the fuse. I am sort of aware that there is a problem with too much fuel. My mileage is VERY low, like 10+\- MPH. The new-used injectors made the car a whole new creature, but they didn't solve the problem.

When I say the car doesn't even have to run for 15 seconds to bring on the condition, I'm hoping that will be the biggest clue for someone here on the forum. The car isn't really "hot", I mean I can just about lay my hand on the exhaust when I kill it.

Please help
