1995 YJ 2.5L fuel problem

When I try to start my jeep the starter is cranking the motor but no fuel, if I leave the key in the on position I will hear the fuel pump kick on 30 seconds and sometimes up to 15 min. later and then I can start it. It seems to take longer when it is colder out, but once it the fuel pump kicks on it starts and runs great. Could this be a sensor, fuel pump or a sending unit , auto zone and advance auto give me different answers and I hate to guess $$. Also when the fuel pump starts pumping the shift light flashes at the same time?? Any answers would be helpfull. Thanks, art

I am working through a similar issue. Here is a link to help find fault code information if you may have a sensor problem:

There are a couple vacuum hose connections on top of the gas tank; make sure these are connected.

Check gas line pressure at the fuel rail (Shrader valve) before start, during cranking, during engine running, immediately after stop, and a few minutes after stop. This may tell you something.

sounds like one of my posts from a few months ago. read them and let me know if its the same thing. I'm in the process of changing the fuel pump now. I hope that is the problem. It just stopped coming on, even when it was warm.

Well I have dropped the tank and checked the wires running to the tank and the pump is working fine. The computer or fuse block under the hood seem to be my problem so I guess it will be going to the shop to get checked out by a electrical pro. I was thinking it could be thepickup coil in the distributar cap but no power to that or plugs, I'm just puzzled??

General motors had problems similar to this for a while first. if your fuel filter i clogged it can be part of the problem if you fixed that check for melted wiring connections. gm sends you connectors with most fuel pumps now and its due to clogged fuel filters.. if thats not the cause. Hook up a fuel pressure gauge and look at the cranking pressure and if thats good check the regulator by disconnecting the vacuum line. before you get into all that make sure you have good signal comming from the crank sensor to the ecm, and the ecm signal coming out is good. let me know if you don't find anything.

Mine had a fuel problem, but, was getting to much fuel. Seems there is a problem of fuel tanks colapsing, blocking the return, causing to much fuel presssure. I installed a new tank, then went a step further by chopping the return at the bottom of the tank a couple of inches, and welding a washer on the pipe, and puting a pvc pipe, with holes drilled in it, to help support the tank. As an extra measure, I turned the whole return line inside the tank, into a sprinkler, by drilling holes all over the whole thing
