YJ not starting

I have an 89 Jeep Wrangler that will not start. It will crank for about a second but then everything turns off. I have checked the fuel pump, ignition switch, relay, and fuses. If I put gas in the carb it will crank. Any suggestions on what next to look at?

Thanks

What engine? The engine will actually turn over (not just clicking) and then everything shuts as if someone yankee the battery?

Was it running previously to this problem? Have you change anything recently? What engine as well?

I say something electrical regardless. If it just stops cranking something is going on with the starter the battery or the wires between them all the way up to the key.

89 YJ.. My first jeep and I won't let it go. ▀||||▀

Current Project: None... I disgust myself.

Yes you are correct it cranks but then everything turns off. The engine is a 2.5L.

I think the OP means the engine fires then shuts off; is that correct? That seems to point to a fuel deliver/pressure issue.

when you turn the key to the on position, not start, does the check engine light come on?

Well we finally found out the problems. One the computer had to be replaced, once that was fixed we found out that the fuel relay did not have sufficient ground. After replacing the ground on the relay the jeep started right up.
