Welcome to Allpar. Sounds like you may have a broken timing belt to me. But, I'm not a mechanic by trade.

Start by checking for spark and fuel, as usual, and post back.

 

[maintsuper7]

Have fuel no spark,code shows up as P0340 think that's crank sensor,

 

[maintsuper7]

Purchased the crank sensor,had to remove the starter to get it out and installed new one.I believe I need to clear the codes before proceeding.The following codes are present P0016,P2074,P340,P137 and finally P0138.
Due to the fact that the battery is in the wheel well,can I clear the codes with a OBD2 or do still need to disconnect the battery.
Thanks to all.

I won't swear to it, but I think if you disconnect the negative cable at the jumpstart connection underhood, that will disconnect the battery.

 

[KOG]

Should be no need to clear codes, just start it and they'll clear after a while anyway.

 

[maintsuper7]

Well replaced the cam sensor and crank sensor,still no start,any suggestions would be appreciated

 

[CudaPete]

Had a similar problem on my PT. It was a worn wire in the wiring harness.

 

[maintsuper7]

Which harness did you find it.I checked all I could find???

 

[CudaPete]

Trace back the crank and cam sensor wires. There is a place they connect. This is where you will find the problem.

P0016 may be the clincher. Is the timing belt jumped or broken?

P0016-CRANKSHAFT/CAMSHAFT TIMING MISALIGNMENT
When Monitored: Engine cranking and Engine running
Set Condition: Powertrain Control Module detects an error when the camshaft position is
out of phase with the crankshaft position. One trip fault.
POSSIBLE CAUSES
INTERMITTENT CONDITION
CHECKING INTERMITTENT CMP SIGNAL WITH LAB
CMP WIRE HARNESS INSPECTION
TONE WHEEL/PULSE RING INSPECTION
CKP WIRE HARNESS INSPECTION
TONE WHEEL/PULSE RING INSPECTION
INTERMITTENT CKP SIGNAL
CAMSHAFT POSITION SENSOR
CRANKSHAFT POSITION SENSOR

P2074 (MAP/TPS correlation) may have happened at stall. Disregard this for now.
P0137 and P0138 are downstream O2 sensor both low and high voltages.
There was a TSB# 18-010-03 for false P0137 and P0339 (crank sensor) that involved a PCM flash.

 

[maintsuper7]

I found that the timing belt had broken. I hope no damage has been to the top end. Will keep you all in the loop. Thanks tp all that assisted
:runaway:

 

[Bob Lincoln]

Was it the original timing belt? Service intervals vary from 60,000 to 100,000 miles. What usually kills them is overheating and exposure to grease and oil.

 

[chuzz]

Hmmmm , seems like someone suggested that about 8 days ago! I don't know if that's an interference engine or not, but I'm sure IC or one of the more knowledgeable members will let you know.

 

[ImperialCrown]

2.4L is not a valve-to-piston interference engine. A valve-to-valve hit could occur if conditions were wrong, but is rare. You should be safe. Replace the water pump and idler pulleys (bearings) as well as the belt.

 

[maintsuper7]

Pro you were correct,I suspected that as well but hoped it wasn't due to the issues involved.
On the bright side I have a friend who is really into Mopar and will do the job for 600. I buy the parts,another 250.00.Cheaper than a car payment!
BTW
I agree that it is not entirely a interference engine,Mopar also says in a reply to the question that as well.
Thanks to all for the info,will let you all know how I make out

 

[maintsuper7]

Hey folks back again,new belt tensioner and all.Ran great for 2 days now I have the ce light on and a p137 code,sensor,should I just replace both of them? Thanks ......again

 

[B10alia]

Based on the P0137 and the P0138, it sounds like something isn't kosher with your O2 sensor. I would check your wiring and grounds before you go after the sensor itself.

 

[maintsuper7]

Unusually Active,
I was told after a timing belt change it may trigger a CE light for a day or so then clear. What do you all think does this sound right? Sensors are not cheap as you all know. Should I continue to drive it. There are no issues with performance, actually it is running better than before the timing belt broke, go figure.....thx again :drive: Prolific how bout you
