I have a 1990 Cherokee Laredo with 105,000 miles. I have owned it for 9 years with no problems. I dont drive it much in the summer but do use it in the winter. Yesterday I started it after it had been sitting for a couple weeks and as usual I had to crank it for 5-10 seconds before it would start. Today I went to move it again and it wont run. If I pour a little gas down the throttle body it will run for a few seconds. Is there anything I should check first or is it the fuel pump? I did change the fuel filter and it does have fuel in the tank. Any help is appreciated.

Thump the bottom of the gas tank with a piece of wood or rubber mallet, then try to start it. If it starts, then your pump is bad.

Sorry ive been busy. Ok it will ocassionaly start and run for about 15 20 seconds on hi idle then just run out of fuel and die. If I can quickly "feather" the throttle it will keep running as long as I keep it up. Its seems as though it is only getting fuel when I 'hit the gas' When I turn on the key I can hear the pump build pressure but its like it only gets fuel when I call for acceleration?
Any ideas are appreciated,

So it sounds like the fuel pump is running.

Throttle position sensor? Idle air control valve?

Is it giving you any codes? [ok I don't know if the 90 had OBD or not]

Tried it again just now and it started right up and ran for 5 to 10 seconds then dies. It starts goes to hi idle @1500rpm then starts to idle down then just stops as it runs out of gas. It will start right back up and do the same thing. Would this be the throttle position sensor as suggested? Should I check for fuel pressure also and if so what should it be and when? Does anyone know of a way to test the tps?
Thanks for all the help.
