Crank no start condition
I have a 1986 Cj7 with an LSX engine and just recently I drove it to wendy's drove fine no problem when i went back to start the beast all I got was a crank no start condition. I usually use to get the fuel pump noise that comes on when I would turn the key onto the on position a long peeeeeeeeeep noise now nothing. I removed the fuel pump and had my father take it to a shop to have it tested and according to him it sprayed fuel everywhere. I checked all the fuses that im aware of and they were all good I dont know where the relays are on these jeeps but any help would be appreciated it

Well first can you find a place to put in a fuel pressure gauge? that will tell you if the pump is working and your just not hearing it. if no pressure then make sure you have power tp the fuel pump. if yes then try new pump, if no start back tracking the electrical. who did the wiring? do you have a schematic for it? This should give you a couple of ideas good luck!
