I have a 1995 Ranger with a 3.0 V6 and auto transmission. I went outside to leave and the truck turns over but won't start. The fuel pump won't run and it also has no spark. There was a 30 amp fuse blown in the engine bay fuse box that apparently goes to the pcm. I replaced the fuse and the truck still has the same symptoms but the fuse did not blow again. I checked for power on one of the coil pack wires and it had 12 volts. I have checked all of the fuses in the truck, swapped diodes, and swapped relays and no luck. I suspect a bad pcm or wiring. Need ideas and if you guys know how to test the pcm I'd appreciate any knowledge.

 

I would swap out the ecu relay($5).......that needs to work for the fuel pump relay to work..........any chance your ignition switch is shot?

 

It's plausible seeing as the truck has north of 200,000 miles.

 

That or the ECU, Im tracking that on my truck now because im getting no power to fuel pump
