Sorry forgot. Its a 1994 S10 with a 4.3L engine V6. Again whats really throwing me off is the fact that I have fire at plugs and cannot start it for a few seconds by opening the throttle plates, spraying directly into intake. The parts arrived, AC Delco CR43TS plugs, MSD cap and rotor, MSD coil and new wires. I know I didn't need them but it was time for tune up anyway so why not. Trying to cover what I can, I found the fuel pump relay (under the dash on a 94) and have 11.6volts to the relay. The horn relay is right beside it, same type, swaped them and both relays work. And I agree with you, does not seem like a fuel problem, but then again the pump went out 2 weeks ago, changed it and everything was dandy for two weeks. And by checking voltage to the pump relay with switch on (voltage present) that eliminated the switch as well. The pump I bought was from Advance Auto, hey I had no choice, had to bum a ride to get there, but I have one on hand now, a Delpa that I got from NAPA. Should be OEM.
Now you suggested disconnecting the MAP sensor, ok, not sure exactly where it is but it should be on top of the intake somewhere. I was able to borrow a vehicle so at least I got wheels for now. Thanks for taking the time to respond.
