Replying to: heeply (Feb 09, 2008 10:42 pm) Crank positon sensors commonly fail. Check to see if you have spark at the coil. If there isn't spark then its a good indication your crank position sensor failed. Its abot $75.00   The sensor has a plug on the driver side of the engine and the sensor bolts to the bell housing of the flywheel driver side. Its a pain to replace without a universal joint and 18" extension. Replies to this message: slatzman (Jan 13, 2009 5:05 pm)

Replying to: bovee (Feb 15, 2009 7:04 pm) my prob was solved the first mechanic put the crank sencer in crossthreaded spent alot of money to find that out sounds like you have a loose connection the computer we changed was the main computer had to program the whole thing again in the end we put the old one back in.good luck.

Replying to: jeep_buider (Apr 12, 2009 8:16 pm) the original mech put the crank sensor in loose took forever to figure it out but our new mechanic figured it out took him some time but he got it.check your sensor again
#28 of 40 97 GCL Engine Stall by vfreen Apr 20, 2009 (9:35 am)
Help!!! I have been going through this problem since November. 3 shops and now with the dealer for the 4th time in a 6 weeks. No matter what the speed, the car will just cut off. Sometimes it starts right back and sometimes it does not. Any suggestions will greatly be appreciated. I have changed the cam shaft sensor, EFI module, fuel pump, plugs, wire, distributor, rotor button, battery and the pins on the computer connection. Did I miss anything. Now the dealer has a team working on it. Please send prayers .   Vfreen Replies to this message: john_ii (Apr 25, 2009 8:03 am) jcalcutt (Apr 25, 2009 2:52 pm) slatzman (Apr 26, 2009 11:34 am) vfreen (Apr 26, 2009 6:05 pm) jgcgta (Nov 02, 2009 8:42 pm)
