Did you remove the crank position sensor when you R&Red the trans? If not, chances are good, you broke it. (and, no spark would tend to indicate that....) It's in the bellhousing, passenger side, hard to see, harder to touch.... held in with two bolts. Pull it, see what it looks like, take it from there.

 

yea i know where the booger is (think they could have made it harder to get to like maybe in the oil pan lol)
unless not removing it to take out the tranny damages it, i was aware of it before i pulled the tranny and was carefull when taking the tranny out and putting it back in.
it just amazes me the truck has never failed to start untill now, and like i said i was carefull of it on the rtemove and install

 

Have a look at it, it really is easy to trash the thing when doing trans R&R. Best bet is to remove it first. Might have just pinched wires too for that matter.

 

ok, i'll try to get it pulled today and get back to you on it's condition.
of and i know the wires arent pinched, checked that allready, when at first i dissconnected it at the harness to see if it threw a code so that might have helped me see if it was the problem

 

well visually it looks fine (i know that means nothing) but just thought i would mention it. can i test this with my multi meter? i only ask so i don't go dropping money on a part that may not fix the problem, it just seemd weird to me that it just (poof) quit working while sitting, not being drove or started and onviously not due to damage done by me on the transmission removal and install.

 

Ok, three wires.

Violet w/ white trace: 5 volt feed.
Gray w/ black trace: Signal to pcm.
Black w/ Light blue trace: Sensor ground.

Check resistance between feed, and signal wires, and ground. None of them should be zero.

You can try moving something metal past the pickup end of the sensor, and see if resistance changes as well.

Make sure you are getting 5 volts on the sensor feed wire from the PCM.

Make sure the sensor ground wire heading off to the PCM actually IS a ground. (there are like three splices in that wire.......)

 

ok i may need a little more in depth direction on all that, i can check voltage and check for continuity, i did set the meter to 20k on what i was told is resistance and touched all the tabs on the sensor and looked for readings, and it did nothin, just read out with the 1 as if i were haldong the probes apart from eachother

 

That's bad. Grab a new crank sensor.

 

i know your proably getting tired of me by now lol, i have a couple more questions.
1. i didn't have the sensor hooked up to nothing i just touched both probes on the pins for the sensor, and switched back and forth to check every combination of the 3 pins, is that right (sorry i just wanted to make sure i was suppose to test the pins against themselves and not agains ground or another wire the feeds the sensor.

2. would the cps be the same on a 94 grand cherokee with the 5.2L in it, i have one here that runs and was going to try it also before i dumped the money on a new sensor , im pretty sure they are the same but i wanted a second oppinion on it.

also i thank you for all your help

 

yep, that's the correct test.

As for the cherokee sensor..... it 'should' be the same..... pull it out, have a look, take it from there. Test that one with the meter as well, and see what readings ya get. Better be different than what you got on the first one. (you could conceivably test it without removing it too.....) If it looks the same, toss it in, see if the truck starts.
