Hay everyone I need help I am new both to forums and to Jeeps I just bought a 93 Grand w/ a 4.0 it sat for 41/2 years, put in a new(used) fuel pump and a new starter fresh fuel and it fired. I drove it down the road and back about 1/8 mile. i drove it on my trailer and brought it home. I drove it around agian for about an hour in some trails by my house pulled it back in the garage shut it off then tried to start it agian and since then it will just crank but won't fire. I got spark, and when I turn the key on the fuel pump is kicking on I even pulled the fuel line off at the fuel rail and fuel shot out Just put on a new Crank Position sensor still the same cranks but no fire, if I take a spray bottle and spray fuel in the intake it will stay running as long as I keep spraying the fuel in. I am at my wits end and need help. PLEASE

I had the same issue when I got my 95 - Turned out the battery connection was bad or intermittent - long story short it was my theft detourant device killing the engine. Are your lights Flashing? thats what gave it away to me.

you might try seeing if you have injector pulse at the injector connectors, use to smal jumper wires and test light. you take the wires and touch the connector ends and take the test light and connect there ends to the wires,basically making a loop and have someone crank the engine and it the light should blink. I hope i describe it good for you
