93 Gcl

I got in my jeep (Grand Cherokee Limited) this morning to head off to work and she started, ran for about 1 second, then died. I tried numerous restartes while applying the gas pedal, thinking more RPM's might keep her running, but no luck. I started to check vaccuum lines, all connected and not detiorated to which I need to replace any. Started to pull spark plug wires off the distributor to check the leads, well I Pulled 4 total leads out of the distributor cap. So a quick run to autozone left me with an $80 dent in my wallet. So far I've replaced the Distributor cap, rotor, and Idle Air Control Valve. Tried to start again, same problem, only now I've tried to start it so many times that my battery is run dead and can't barely get a crank out of her. I tried a jump start, hooked my chevy truck up to my jeep, let the car run for about 10 minutes and same thing. Now I'm at work and wondering who I'm gonna have to bug for a ride tomorrow in the A.M.
When I get home today, I'm stopping by the parts store to buy a fuel filter, she hasn't been changed in a couple of years, even though I don't think this is the problem. I checked at the fuel rail and there is gas there. Not sure what other info would be helpful. 93 Grand Cherokee Limited, 170,000 miles, Inline 6 cylinder 4.0Ltr. All Wheel Drive. I'll be looking back in about an hour to an hour and a half for a reply post. Thanks in advance for whoever does.

Could be a fuel pump, a coil, or something to do with the map sensing.
Jeeps if you hold down the gas when you crank will flood the mtr.
Try taking a spark plug wire off and put a spark plug on it and ground it on the mtr while someone cranks it. if you see no spark its ign. If theres no spark its got to be fuel problem.

You still have some residual Renault technology ( I feel for ya).......Check for spark as has been mentioned.........Then you need to check injector pulse (A "noid" light would be handy) If you have NO spark and NO injector pulse, more than likely the crank sensor is the culprit.........Which can be double checked by scanning RPM's while the car is cranked..........No cranking RPM??......Computer see's no need for spark or fuel

Just the battery

I went to the local auto parts store to have them check the altenator for me and they checked the battery first. That was the problem, good thing is that it was still under it's 7 year warranty and I only paid $46 for an equivelant battery. Hopefully this one doesn't do the same thing 4 years from now. Thanks for all the help on this guys, definately had some good suggestions on things to check.

I'm confused. Nowhere did you mention any kind of cranking problem. I think we were all under the impression it was a cranks-but-no-start problem. If you were getting good cranking before, I fear the problem has only gone into hiding and will be back.

No

It plainly states in the first sentence that I wrote on the first post, "she started, ran for about 1 second, then died." The only reason it led to a cranking problem was starting it so many times and it kept dying, so the altenator never got a chance to recharge the battery.

Okay. But if you got a bunch of restart attempts that eventually ran the battery down I don't see the connection between the new battery and the problem being fixed, i.e. why didn't it restart on the first, second or third restart attempt while the battery still (presumeably) had enough power to crank and start and/or when you were boosting it? Somewhere along the line either the problem has gone into hiding or in the course of everything you've done the basic problem was corrected.
