I just bought an '89 Ranger XLT, 4x4, 5spd, 2.3 (Twin plug w/o distributor) for a DD. It has been parked for 6 months (they said). To begin it wouldn't get fuel to the fuel rail because the pump wasn't working, so I pulled the bed and replaced the pump/sending unit and the fuel filter. Now it will run but only if you work the throttle back and forth. If you try to hold it at a steady RPM or let it idle it will cut off. If you squirt carb cleaner in the TB while holding the throttle half way it runs fine. I haven't checked the pressure yet but if you push in the valve on the fuel rail it seems to have great pressure. I also tried unplugging all injectors but one and can get it to run off just one injector (tried that with each injector). I have also replaced the plugs and wires, and the TPS. I checekd the compression and all 4 ranged from 198-205 psi. Thanks for your help!!!
EDIT: Just checked the fuel pressure, 38 w/ switch on and 45 while running.
EDIT: Forgot to mention that I used a transfer pump to pump all the old gas out of the tank and put 6 gallons of 93 octane back in it when I changed the pump.
EDIT: FIXED.... Turned out to be the MAP sensor. Thanks for your help.
