I just replaced a timing chain in my 2002 dodge intrepid SE 2.7 liter .The problem is is that when I hand crank the crankshaft the timing chain goes from tight to loose.There is a slack in the chain on the passenger side.It seems to go from tight to loose upon every revolution of the crankshaft.

The timing is set by aligning the marks on the camshaft gears and the crankshaft gear with colored links on the chain. See the included link for guidance (it's for a Sebring, but the information is the same for an Intrepid). Be aware that rotating the engine after initial timing will change the relationship of the colored links with the gears. This is OK, just BE SURE THAT THEY ARE ALIGNED when the chain is INITIALLY installed. Chrysler Sebring Concorde 300 2 7L timing replacement Cloyes kit 9 0397SA

If you have a timeing chain you have timeing gears witch have marks on them .These marks need to line up even if you have to remove the chain or the gear don't turn the crank or the cam the gears have key ways that olny let them slide in the shafts in 1 spot the chain will go on in any pisition .

are the wires on right?

possible fuel pump failure or coil -coil pack bad - or timing belt needs replaced

The crankshaft sensor is located on the passengers side of the transmission housing, above the differential housing. From what I've heard, its tough to get to.

I have a problem with a 1999 Dodge Intrepid 2.7. Looking for some help or suggestions.

Problem: I only have a spark from the #2 coil.

Background:

Vehicle purchased from an Auction and would not start. The vehicle would only backfire. When I removed the valve covers I found that one of the rocker arms had popped out. I replace the heads with heads from a 2001 Intrepid 2.7. I used the cams, primary and secondary timing chains from the 1999 heads. Not sure if I used the original primary (left) cam sprocket from the 1999 or one I purchased in a kit from a Dodge dealership. I tried to use the new primary timing chain but it was not the same. The replacement heads were surfaced and a new head gasket was used. When I tried to start the vehicle it had no spark. The vehicle had set at several locations and parts may have been removed or changed.

Solutions Tried:

I tried 4 ASD relays with no effect. I then tested all 4 on a 2002 Intrepid 2.7 that runs and all worked. I then discovered that the Crank PS has missing. I replaced the Crank PS with one from a 2002 Intrepid 2.7 with no effect. I then replaced the Crank PS with a Crank PS from a 1999 Intrepid 2.7 and got a spark at the #2 coil only. I then replaced the PCM and TCM from the same 1999 Intrepid I got the Crank PS from and still only have spark from #2 coil. I then changed the Cam PS, still spark only from #2 coil. I have tried several coil packs on connector #2 and all have spark. Each coil pack that sparks on #2 will not spark on any other connector. Spark from #2 coil is weak.

I then replaced the wire harness from the PCM to the coils and fuel injectors and still only have spark from the #2 coil. What am I missing? Any suggestions, advice or related information will be greatly appreciated!

Thanks!

If you mean the 2.7 liter V6 (I think the Intrepid only came with the 2.7 or 3.5 liter V6), the answer is yes. The water pump is driven by the timing chain.

your intrepid doesnt have a timing belt it has a chain. there are major problems with these engines, theres a big one with the chain jumping due to a tensioner breaking or a guide,heres a diagram for the chain setup.this is a very important setup make sure you use correct sprokets in the right place and also if it jumped timing il bet you may have some bent valves,

the timing marks are located on all four cam cogs and the crank cog. there are also timing marks on the chain itself. there are three gold colored links on the chain. these corospond to the three cogs. good luck.

dear friend-if you are positive that all the repairs were carried out with great care,that the timing is right,and you got spark and fuel,all the valves close propely,then it should start,if the sensor was ok before you stripped the engine why should it be faulty now.
