WHat the compression at?
Well, then this is our problem.
Cylinder Compression 170-225 psi   Maximum variation between cylinders must be less than 25%.
So at 150-162 is going to make no spark out of 1 and 4 coil ?
No.... I think the motor is not timed correctly. THat will make no spark out of 1 and 4 coil.
Number 1 and 4 cylinders are sister cylinders.
Well, if the timing marks are in fact dead on, you could have a broken, missing or sheared cam or crank gear pin that holds the gear in place in relation to the camshaft or crankshaft.
Just put your hand on the exhaust pipe and have someone crank it over. If your hand gets sucked in at all during the cranking process, the engine is not timed correctly.
If broken or sheared pin then cam woul just sit as if the timing belt were broke or be intermitentlty turning and engine would not be barely starting and would be making plenty of noise or just turning and turning without the 10 second almost start.
Been researching this issue and the below is about identical issue with this engine posted by someone on another site with an answer below.. sounds very likely and wondered a second opinion as i have tried many basic things...
pegasus757 02-03-2004, 03:45 PM car starts runs fine untill engine gets warm ,(not hot,.. indicator shows about mid way, and fan does not come on ,i can hold the rad hose.). When it dies the front coil works, spark at 1 and 4,the back side has no spark. the coil has 3 wires.. center is pwr... fwd wire is for fwd coil and aft wire is for the aft coil. when it died out i swaped the fore and aft wires ...now the aft coil has spark and the fwd does not. Checked continuity from pins at coil to pcm ...checks good,Ok so I belive pcm is not giving the signal (ground) needed to energize and collapes coil , so I changed the pcm ...still the same results. has any one had this problem or could some one point me in a logical direction. THNX in advance PS... remember, test dont guess.........HERE ARE THE RESULTS.....the crankshaft sensor would get warm and the pickup inside caused an interrmittant open.. found the problem. Went to the zone ,sensor was 28.00 also needed a special pig tail (they didnt have) ,went to dodge they wanted 88.00 for sensor,so i just bought the pig tail...car runs fine now
ABSOLUTLEY! A bad crank or even a bad cam sensor would cause this problem.
I hope it is just a sensor or something simple that fixes your car too!
