plutonium233

My brother's 94 Ranger will crank and run fine for awhile and then die suddenly. He says the check engine light flashes once or twice and goes out. Sometimes it will crank back up, but most of the time it has to sit for quite a while. I checked the fuel pump and fuel pump relay and they are fine. When this problem occurs and you turn they key on, the fuel pump won't kick on like it should before you start it. I am also sure the injectors aren't firing when the problem is occuring because I can jump the fuel pump relay and make it come on and it still won't start. I can spray fuel in the intake and it will start and run for a second or two. I am unable to read codes from the EEC. I think the computer itself is losing power because the check engine light does not come on when I turn the key to run. What wires should I check for power on the EEC?

Thanks,
Kyle

Oh, I forgot to mention that I swapped the EEC relay and Fuel pump relay and still nothing.
