    Thank you, I took my jeep to the mechanic and he changed the fuel pump and I just brought my jeep home and it did the same thing. I'm going to take your suggestion and test my battery. Thank you again.

First of all, what type of a mechanic looked at it and diagnosed it as the "computer"? A certified dealer-type technician, or an independent shop mechanic? I ask this because a vehicle's engine ecu is very frequently mis-diagnosed when it may be something as simple as a loose connector. What exactly happens? You crank, the vehicle starts ok, then runs good for a while then dies, or dies right after starting? Does it run rough after you start it? Without further info, I'd say you may have a bad battery. The engine control unit (ecu or "computer") is very touchy, and what happens many times is that your vehicle may crank ok, but while cranking, the voltage will drop too low, and erase the computer's recent memory ( things like throttle position, crankshaft sensor variation, etc.). So when it does fire, it will not idle properly, or sometimes will not run at all. Chrysler, Dodge, and Jeeps are especially susceptible to this. One thing you can do is if it cranks then starts, rev the engine to keep it running, not mash the pedal, but hold it at about 2000-3000 rpm for 10-30 seconds and after that, gently release the pedal, and let idle. if it runs ok after that, drive it to buy a battery. If this is not the case, you may need some more serious electronic diagnosis. Look over the obvious things like your battery cables to ensure they're tight and no corrosion, also follow those cables to the starter/engine/or exterior fuse panel, and make sure the connections are good. I hope this helps. I would definitely get the battery load tested (they do this at autozone for free), and go from there. Good luck.

My 1994 jeep grand Cherokee Laredo will not start or stay running.turns over but will not fire,but then sometimes it will.when it does start it runs very rough and will stall if I try to restart it...

If it's been sitting a while it's always a good idea to put some sort of gas treatment in it. Ethanol added to gas nowadays is bad about getting water in it if it sets.

1994 jeep cherokee laredo using lots of oil. Believe it's spewing out when I drive 'cause found lots of oil on wheel covers. Someone said it's probably front seal. Before I take it to...

I dont see how the oil made its way to the wheel covers, but as for the oil loss, it sounds like a broken seal, more than likely your from main or crankshaft seal, that equieres mechanics expertise and tools to replace, no choie but to take it into the shop.
Good luck.
