I have 1989 ford ranger with the 2.3 in it. i was driving it and the truck died. At first i thought it was the fuel pump but at first i checked the fuel pump relay and changed it. the fuel pump won't turn on when the key is turned, it only turns on and keeps pumping when you jump the fuel pump relay with a piece of wire, but even when i jump the fuel pump relay fuel gets to the fuel rail but the truck wont start. It will kinda start and barely run when i spray starter fluid but wont run off of its own fuel and barely idles, it wont get to full idle on starter fluid. The fuel pressure is good when i jump the relay but that's the only time the pump will turn on but still the truck wont even try to fire. Ive gone through everything i could think of and cant find the problem. I'm down to maybe the ecm or a new pump. Please any help or suggestions is much appreciated. The motor and tranny only have about 35,000 miles on it because it was swapped by a previous owner.
