I have a 93 jeep grand cherokee limited 6 cyl. auto. Anyway this is the only vehicle I have and my husband and myself don't live in the same town. I have to get it fixed by this weekend to take the kids to school next week. Anyway heres the deal. I bought it off my bro and next day after fueling, it died wouldn't crank no matter what, let it set until the next day it crank rough. It took it a bit and finally starting catching and would run great for a few days. Then all of a sudden it started spitting and sputtering and got worse if I touched the gas. It kept doing that for a few days. Then I turned it off and it didn't want to crank back, after turning the key off and on b4 tryin to crank it it cranked rough again (not wanting to run) anyway got it home. Had to take kids to bus stop 12 miles away next day barely got it home. It spit and sputtered worse than ever and didn't want to hardly move. Then it wouldn't start at all, it will turn over but nothing. Changed the fuel filter on it, the spark plugs and plug wires nothing.I can hear my fuel pump whirring. My cousin is willing to help me, he says that it's the crank sensor (at least thats what advance auto told him it was). What is the possibility that it's that? I unhooked the sensor and hooked it back and it still won't start. I am at wits end and cannot afford to pay out alot for this jeep I mean i just spent 1200 buying it from my brother. Any and all help will be greatly appreciated. He will be here tomorrow to take the part off and take me to get the sensor for my jeep. Please Please someone help, I don't want to pay out $55 to get this thing and then pay him to put it on just to find that it doesn't work.
