Well i went to fire it up, and it's turning over, but no fire, check the codes, 0320 (crank sensor on the tranny) and 1490 1498, two relays...

i've got the crank sensor in front of me, and there's not so much as a scratch on it, and the magnet is plenty strong... made sure it had a good connection too... going to go throw it back in and be a cave man and prey for fire.

 

my camshaft sensor just decided to quit on me Friday evening. turned over but did not fire!!

 

Ignore the 1490/98 codes, they always appear when you crank the engine to long without it firing. Fan overspeed, fan underspeed.
Are all the pins straight and clean? Sometimes it's something just that stupid or the tranny isn't fully in park. Did you hear the fuel pump buzzing away when you turned the key?
Good luck, hope it fires up for ya.

 

yeah i just saw your post...
i put the sensor back in and still nothing... what the hell...
grrr

i even checked my plugs, their "normally worn" little brown-ish and a little grey on the electrode... im just having the hardest time believing this sensor has gone bad...

yeah checked the pins and its all copenhagen... fuel pump is buzzing like normal
the thing is its turning the crank, if the park neutral switch was off it shouldn't let me do that...

 

Have you tried to start it in neutral?

 

I tried that too! nothing. all back to normal now she is fixed and ready to rip again!

 

thats what im about to do, just taking a break with a cold one... its hot in north carolina, gotta keep well hydrated HAHA

 

Just watch out for the damn spiders. Try changing out the starter relay with the horn. See if it does anything. The neutral switch is in tight? Brake pedal/ trans interlock is operating?

 

switch is in tight, even flipping it does not remedy the start issue, no start in neutral, still turns over no fire and 0320 code..

brake trans interlock working just fine...

im about to break out the hammer...

 

Just don't hit it anywhere that would set the airbags off, I think that would be the end of the Jeep :D
If I think of anything else I'll let you know. You do realize it's probably something incredibly simple...
