97 Intrepid wont start

[duelly_95]

I have a problem, after driving into my driveway and shutting off the car, the next morning it just cranked and wouldn't start. I can hear the fuel pump running when I turn on the key but the engine just wont fire. Any Help would be Great.
Thanks: Roger

does your check engine light come on? If there are any codes stored, try this, turn you ignition key on/off 3xs ending in the "on" position. Count the number of times the check engine light flashes. For example, if it flashes twice then pauses and flashes another 4xs that's a code 24.

The Only Code that comes up is 55, End of codes, I have looked a little further into it and It seems I have no spark, Any Idea what could just instantly fail like that? I have checked every wiring connection and fuse that could be Related to Ignition or fuel. but by pulling a spark plug and cranking the engine I forund no spark.


Still Looking:Roger

I'm surprised you have no codes. It sounds like your crankshaft position sensor has pooped out. It's mounted on the passenger side bellhousing w/ a 3-wire connector. If that's ok, you could have a bad coil pack, driver or a bad connection at your ignition coil pack.

[duelly_95]

is there any chance that the crank sensor can be tested, or do I just Replace it and try that ?

[duelly_95]

Well, After a new Crank Position sensor and a coil pack It still does not start I'm begining to wonder what else could possibly be going on. Any more help would be great

[duelly_95]

After a new coil pack and Crank sensor also a Cam sensor I still have not been able to get htis thing to start, I replaced the timing belt and water pump while I was in there. I wish I knew what was going on.

[theFREAKnasty82]

have you confirmed that you have no spark?

[jphutch]

Did you replace the wiring harnesses on the cam and crank sensors? That tends to be where the problem originates in the first place.

[duelly_95]

Yes I have confirmed that I have mo spark, and I havr run out of Ideas on this car.

I have the same problem with my 2002 Intrepid. But after a few attempts it starts fine and then the whole day it starts OK until the next day or so when I try to start it wont start. I am interested in the code and what it does to the starting? I did not count the number of times I turned the key to on/off before it finally starts but will keep a count the next time to see if it follows a pattern. Is there any way to null this code if it turns out to be the problem here? Thanks! Cash R.

Check your wires going to your coil pack, make sure you don't have any spread terminals or corrosion or any other crap that causing it to not make contact. Also, if you can find a wiring diagram for your car, see if you can find any wires that may be shorting itself out along the body. Lastly, have your cam sensor checked. Which motor do you have, the 3.3 or 3.5?

[duelly_95]

I have wiggled and jiggled all the harnesses and checked for Loose connections till I'm blue in the face, The engine is a 3.5 and it is still not showing any codes at all even with an OBDII reader hooked up. This thing is driving me crazy.

I've got the same problem, been eating at me for 6 months. Previous owner said it wouldn't start one day. Gave it to me. I've changed cam and crank sensor, coil packs and computers,all to no avail. I'm wondering if there is a possibility that the ignition switch could be the culprit. Haven't located a full wiring diagram to check if it's possible for the switch to operate the starter and not the coil packs. Both my sensors give the correct readings as the engine is rotating and the coil has power to it momentarily when the key is turned on, but the pulse to fire it never comes. One time it sparked, and I let it sit overnight to dry out the cylinders and the next morning it was gone again.

have you all tried to check your ASD relay? Check under the underhood fuse box and locate that. Swap it out with the A/C clutch relay and see what goes; possibly you could have a bad ASD relay.
