Jeep wont start HELP - Pirate4x4.Com : 4x4 and Off-Road Forum

TJsahara · 12-09-2007, 10:47 PM

my jeep (99 TJ) has been sitting behind my dorm since friday evening (facing uphill, I dont know if that matters or not, doesnt seem like it should ) and i go to move it tonight and it wont start. Its rolling over and seems like its getting fuel, checked all the sparkplug wires and they were good, just keeps turning over and sputtering. I can hear the individual cylinders hitting but it just wont crank. Sometimes she does take spells like that but it usually cranks right up after a little pat on the gas and turning it over for a few seconds. What else should i check? I will have to move it tomarrow due to freshman parking bull shit. Thanks

do the usual stuff...

check for spark..if u dont have it then start at the battery. sometimes they have enough to crank it but not kick it over...if thats good

move to the coil if thats good, move to the distributer...

if thats good move to the starter...

ok if u HAVE spark, lets look at fuel....

how much gas did u have? any chance some gas froze in the lines? try some starting fluid once or twice see if u cant get it going.

keep us posted

well i had a bout a half a tank of gas and it hasnt got below 25 or so here the past few nights if that low at all. i'll have to check for spark and stuff tomarrow morning, get a buddy to turn it over while i inspect everything and get the hell shocked outta me. Bad thing is I have my biology final tomarrow and I'm already stressed about that
thanks man.

I just had this problem last night. It ran fine the day before but I left the key on over night,killing the battery and sitting in the drive why facing uphill. Gas was dripping on to the floor so I thought that since I have the worst carb ever made that putting it on level ground would help. Nothing. I checked for spark at the plugs, nothing. So we pushed up the driveway, my back is killing me.

Look for a schematic I found one on this site http://oljeep.com/gw/elec/GW_wiring.html

though this does not help you there are many ohter sites like it.
I'm going home for lunch to check voltage to the coil and the points since I left the ignition on all night.

yea but i didnt leave the key on, the battery is strong, i have fuel at the fuel rail (EFI) and all seems well, mother fucker just wont crank. I almost got it to crank this morning but it just sputtered a few times, sounded week and died. What else could it be guys?
Thanks
