I’ve checked the other threads which have given me an understanding of what looks to be a common problem. The car was being driven by my son and making a ticking noise. After he shut it off, engine turns over but does not fire up.
1999 Intrepid 2.7L- No check engine lights or pending codes (initially). I can hear the fuel pump hum when I turn key and checked the fuse. I pulled the driver side front coil and get spark with a plug inserted. Plug did not appear to be gas covered in the cylinder. Did see some vapor (smelled like gas) coming from the air cleaner box.
I pulled the wire off the Cam sensor and tried to start. Because of this I now have a PO340.
The starter turns the motor over at 500-700 RPMs, but the motor sounds to be a higher pitch than normal. I cover the exhaust pipe with my hand and did not feel any pressure when the motor was cranked.
The next logical step seems to be pulling the timing chain cover to check the chain. Any thoughts if this is the right direction or other ideas?

 

I just bought a 1998 intrepid that did the exact same thing. it spun a bearing. the people were driving and then it suddenly died. it had a the same code. the owner changed cam sensor, disconnected the battery then hooked it back up and it was knocking.

you could do a compression test (a lot easier than pulling the front cover).

 

This was ticking (like it needed oil) when he parked it. The starter turns the belts over, so that should mean the crank isn't broke.
I didn't have a code until I pulled the camsensor wire off as suggested in a thread on page 2.
Your compression test idea has merit. I just gotta come up with one long enough (those plugs are a long way down)
Thanks

 

just pull a plug and a compression tester from wal-mart they have a long hose you just hand screw it in that's what I use even on my old 426 hemi.

 

Updated my old compression tester-No compression but pistons moving puffing out vapor when turning over without plug in.

I had 80's FoundOntheRoadDeads that used to eat timing belts, but they used to sound normal when turning over

sounds BAD. probably lost tension on the chain and you got bent valves. I've have a lot of bad experiences with chrysler's phenomenal 2.7. You've just encountered one of their common problems.

 

After taking off the timing chain cover, I hand turned the crank and found a spot where the chain had a little slack going down to the water pump.

After removing the valve cover on that side I found the culprit of the chain slack. A bolt had loosened up and was hitting the inside of the valve cover, enough to wear a slight hole in it. I thought the belts were moving slow for a start.

Haven't had a chance to go farther, but any thoughts on collateral damage?

 

2 teeth off on the timing chain and you got 24 bent valves (personal actual experience!)
