The crankshaft position sensor provides the engine's master timing signal. Without it, the engine won't run. I'd say it has a pretty important role.

ah110 same thing happened to me. what s nightmare.

replaced tthe O2 sensor, still stalled.

replaced the throttle body sensor. still stalled.

ended up being the fuel pump and throttle body sensor combination.

Probably would've been my guess after having cleaned the throttle body.

NEVER ever trust the gap on plugs out of the box!

Removing the IAC and giving its plunger and the oriface in the throttle body it fits into a good cleaning is your next best step. Use some aerosol throttle body cleaner and an old toothbrush on the IAC. For the oriface in the throttle body, use a baby bottle nipple brush.

Don't push/pull/spin the IAC's plunger.

TJe0454 my mistake: i cleaned the throttle body and sprayed cleaner into the IAC. i guess ill take the IAC apart and give it a good cleaning now.

Blackpony04 I've been fighting similar issues and since you didn't specifically mention it be sure to check your IAC.

TJe0454 i got the alternator and battery tested when it first started acting up. alternator was good, battery needs to be replaced apparently. i did do some heavy winching a week or so before this all started up...

TJe0454 mines an 01. no distributor.
04-18-2012 09:40 PM
Fitzey5435 Change the distributor cap and rotor. Moisture is makin you chug and stall out. Sounds like misfire.
04-18-2012 09:12 PM
TJe0454 its not throwing any codes
04-18-2012 05:51 PM
JDsDream Is the CEL on? If so pull the codes and post them up here.
If not, it could be a number of things. ( clogged/dirty filters, bad fuel)

4.0 randomly dying at stops.

as the title says, my engine has been hard starting and dying when cold. also sometimes when at a complete stop. i seafoamed it a week ago. is it possible that caused the issue? just replaced spark plugs because i thought they had been fouled by the seafoam. cleaned throttle body and MAF sensor. thoughts?

maybe bad compression in a cylinder? i just dont know why it would surface now...
