I have a 1994 Ford Ranger with the 3.0. I was driving and it stalled, when I went to start it, all it did was crank. The fuel pump wasn't turning on, so I replaced the relay. Pump did not turn on. Replaced my pump, I heard it running, primed the lines, no start. Checked my plugs and wires, replaced them, still no start. Had a junk yard battery, replaced that. I have spark on the exhaust side, I have pressure in my fuel rail, my injectors show 32 to 36 volts while starting and I have compression. I can't figure it out. Maybe a sensor or something I over looked. Any suggestions?

 

Try resetting the inertia switch you can find instructions online or in your owners manuel. Hopefully that fixes it. I had a similar problem on my 97 Ranger and it turned out to be a broken timing belt. My truck made a whining sound when i would crank it. Ford recommends replacing it every 60,000 I think.
