      I have been thru so many forums my eyes are burning.
      93 ranger 4.0l 6cyl XLT.

      Upon returning to my truck after a bankruptcy(30min tops). My truck would not start. Had it towed. Tow guy even thought it to be fuel pump. It did nothing strange previous to arrival.
      I checked for fuel flow at the filter(with key at COL, i say oil cuase i dont get a CEL). No fuel flow. Replaced filter with new one.
      I removed the bed and replaced the fuel pump($99.00), made sure tank was clean. I tested to connectors(fuel pump-getting power not sure how much). I blew out my volt meter trying to figure out how to use it(lol). Still not working, and no fuel pump noise.
      I then replaced the FPR($98.00). still not working. I switched the FPR out and still nothing. I pulled out my inertia switch and it is seated properly down. I pulled out a spark plug and tested for spark. I am getting good spark.

      I took the old fuel pump and tested it straight to the battery and it works.

      My god it was only sitting for a little bit. It gave no signs of any problems before this.

      I was going to look into a ICM, but Im getting spark.

      Where do I go from here. I will be eternally grateful for any help.

      Fuel pump relay? Under the hood or near the ECM in the passenger foot well.

      Re:

      Thanks for repying tmwalsh. I already checked the fuel pump relay. More likely the whole box is needing to be replaced. Today I am going to clean up some wiring, battery clamps, posts, starter wires, ground wires, etc.
