88 bronco II won't start

I was teaching the Hubby how to drive a standard, :banghead: and he was hopping the truck and could not get it going. I asked him to get out and let me drive becuase we where in the middle of the road. It would not run, kept cutting out badly.

We pushed it home and parked it for the night because it had started raining. The next day I tried to start it and it would not crank. I figured with all of the hopping it probably needed the inertia switch reset. Once I reset it the truck cranked right up.

After it ran for about 2 or 3 minutes the wire to the inertia switch got hot. I immediately turned the ignition off but it was too late, the switch was fried.

I replaced the switch, the wire from the switch to the fuel relay, and the wire from the switch to the fuel pump. I then tried to crank it and it would not start. I checked the feul pressure and there wasn't any. I also did not hear the pump turn on. I ran a hot wire from the silonoid to both pumps and got feul pressure but it still would not turn over.

I have fire at the plugs, and I have checked the voltage capacitor running from the neg battery cable.

I am at a loss...any suggestions would be greatly appreciated!

im not really a professional or anything obviuosly but a hot wire sounds like a short...did the new wire get hot?

The new wires have not gotten hot. I think the short was in the wire that I replaced from the inertia switch to the fuel pump.

I have now also replaced the EEC relay and the fuel relay.

We went and bought a code scanner today and I tested the codes and it said:

the manafold absolute pressure sensor or barometric pressure sensor signal voltage out of specification

and

throttle position sensor signal voltage is too low
