88 Bronco II won't start

My 88 Ford Bronco II won't start, It sounds like it catches, but won't continue running. I put it on a OBD codereader and it gave me the following codes, Key on, engine off: 14,53,67,95 and 96. Any ideas?

From batauto.com:

14 Ignition pickup (PIP) was erratic - Ignition Systems
53 Throttle Position sensor too high - TPS
67 Park/Neutral circuit fault - PNP Transmission Manual Lever Position (MLP) sensor circuit - Transmissions
95 Fuel pump: open, bad ground or always on - Power / Fuel Pump Circuits
96 Fuel pump monitor circuit shows no power - Power / Fuel Pump Circuits

That should keep you busy for a while.

When the codes say fuel pump circuts are they refering to the fuel pump relay?

Thanks for your help!

Possibly, but I think it's more generic - basically anything in the circuit. Given those codes, I think one of my first things would be to get a fuel pressure gauge on it and see what, if any, the fuel pump is putting out. That's assuming it's running at all, which you can check by listening at the filler while someone =turns the key to "on" (not crank).

Those fuel regulators and ignition modules are known for crapping out without warning.
