Concentrate on only two things here: Is there fuel at the throttle body? Yes/no? Are the injectors firing? Yes/no? This will point you to the problem.

I think you just answered the what the problem is. If the test light you put actoss the fuel pump leads barely lights up, you either have a bad ground or power lead at the fuel pump. Take the test light, hook one side to a good ground and the other to the power lead. If it burns bright its a bad ground, if dim bad power lead from the engine compartment, black wire is ground, gray is power. There is an inline connector above the rear axle on the drivers side. With low power at the pump, it runs, but will not build up pressure, i.e. no fuel through the injectors.

Me thinks the red wire is for the fuel gauge. Gray is the fuel pump.

Lack of fuel pressure or volume will keep the engine from starting. I believe OP wrote that with direct power to pump there was no fuel at the TBI unit, if that is truly the case I would be looking for any and all filters and replace them. If vehicle sat for any appreciable amount of time, it is not unreasonable to expect rust from plugging filter(s) up or the pickup screen in tank.

Thanks gang for staying with me. Paul,1995,topflight, and all others, Yea i get a dim light on the ignition side touching black and red. If i touch black and brown --nothing. Touching the red and black wires on fuel pump side with extra battery as power, i have fuel supplied all the way to tbi with pressure. Question--Can i supply power this way at the fuel pump (with spare battery) and then see if it will start as a test? 1995-I will drop tank a little today and see if there is a problem at top,and also all the grounds. Man thanks for the fuse answer. I now can quit crawling from front to back looking for it!!!!!!!!!!!!Going now to do some looking and hope FIND THE PROBLEM.

You mean you didn't try to start it when you had the fuel pump directly powered.
Do it.

Remember now you will only get power on those wires for 2-3 seconds after you turn on the ignition. You will only get steady power with the engine running. Did you keep that in mind when checking?

Yes, put the temporary power to pump and try starting and let it run for a few minutes.
