Worn timing belt

So loooooong story short, my jeep died suddenly in the garage and refused to crank up ever again. Turns over but no sparks. Engine light is on and the code is P0340. I replaced the camshaft and crankshaft position sensors and went thru all of the wiring to the PCM with a multimeter and WD-40. Still nothing. I got fed up and got it towed to the stealership nearby to have them do their magic. They called back and said it's my timing belt that's worn all to hell and if I pay them a small fortune of $580 they will fix it for me.

My question is how hard is it to replace a timing belt along with the tensioner? I'm also worried about having a belt valve... I really dont feel like spending all of my xmas vacation money on this damn thing when ive already spent so much trying to figure it out myself.

2.5Ls don't have a timing belt...
So you should probably take a deep breathe and go back over everything again...

"With a P0340 OBD-II trouble code, diagnosis can be tricky at times. Here are some things to try:

* Visually inspect all the wiring and connectors in the circuit
* Check for continuity in the circuit wiring
* Check the operation (voltage) of the camshaft position sensor
* Replace the camshaft position sensor as required
* Check the crankshaft position circuit as well
* Replace circuit wiring and/or connectors as required
* Diagnose/replace the PCM as required"

580 sounds cheap(for a dealership) for a timing chain, I would let them fix it.

I was wrong in saying I have the 2.5L - they did make that change to 2.4L in 2003.

Turns out the timing belt will cause the P0340 code as well... fml

Pretty much the only other thing it could be on that list is the PCM, and thats way out of my league haha

Yea.. It's getting to the point where i'm running out of groceries and missing things for school. I need a driver now, so I think ill haggle the price down $100 and have them do it tomorrow.

If you can follow instructions and have a good manual (I said good, take the Haynes or Chilton piece of **** and put it back under your beer, it is only good for a cup holder), then it is not that hard. You do have to take all the acc. off the front of the engine (a/c comp (pull it to the side), power steering, alternator, etc...) The only other difficult thing is to keep everything lined up, which again is not super difficult, if you do get it off, a good manual will tell you how to line it up.

A small block ford 1988 to 1996 I can replace the timing chain in 4 hours, Now a 1990 Honda Accord takes me about 8. If the stealership only wants $580, it can not be that hard.

While you are at it consider replacing the water pump. On a ford the water pump is $26, If a jeep is similar I would bolt a new one on.

When I asked him if it was a 2.4L a while back he said it was a 2.5L.
So a little confusion on both of our ends.

Yea i've been reading thru the factory service manual, same one the dealership techs will follow, and it's quite of bit of pita work. I think I could do it myself but I just dont have the time or ability to take a chance when this is my only car/heep. It's priced out at about 2-3 hours of work for the stealership to get it done, I think their rate is $120 an hour. I'll ask them about a water pump as well, Thanks bud.

I'm sorry about that man, I had read it wrong on a forum that they made that switch in 2006-2007 only. Only after looking under my hood did I realize.
