    ignition switch is ok. normal dash display.powers pcm, because it fires fuel pump. cranks normally. lights do not dim. any other suggestions?

    Thank you for your help, but a local mechanic suggests removing the car's anti-theft system. He says they are a big problem to the ignition when they fail.

    auto shutdown relay was one of the first things changed. test equipment shows crank and cam sensors putting out normal signals. am now looking at mechanical problem with idler pulley on valve train, thinking that this may have caused engine to jump time. mechanic doesn't think factory installed theft system is at fault.will have him change the tensioner,re-time and see if it will run. will let you know when it's running and what solution was.

Then you have a bad ignition switch or bad ECU which controls the power to spark/timing/ignition. Those also contribute to no start/spark situations. I would have those checked and change/replace if neccessary.

My first instinct reaction is the auto shut down relay. If this relay can be bypassed or a direct connection by disconnecting the leads and joining the two wires will eliminate its action. I cannot point out why no current is reaching the plugs when you have replaced almost all the electrical equipment, so do give it a try and post the result as a comment..................................sodeep

Why does 91 dodge dakota shuts off power to coil after driving


The auto shut down relay controls power to the coil and fuel injection so if on power is at the coil once the engine dies this is normal check cranking it should return but no spark then test the crank shaft sensor iit is on back of engine passenger side bolted to block.

No power from coil


Cam shaft position sensor, if no, replace crank shaft again, some sensors are faulty brand new... Paper doesn't wear off sensor correctly.

It could be the computer. It could be a relay or something in the wiring harness too.
You would need a shop manual to get the wiring diagrams and test procedures to find the problem.
You need to know if the coil assembly and injectors are getting power from the ASD relay, and if the computer is getting signals from the cam and crank sensors.

1999 dodge caravan new pcm new crank and cam sensor new coil pack new flexplate still no spark, scannner show sync problem, any ideas


If you have replace new cam sensor with no sparks and the coil are good putting out 12 volt, my guess would be the computer it self faulty. cam sensor sense the cam turning and send info to computer telling computer to disperse the charge from the coil pack to the plugs assuming relay, cam sensor, coil, plugs, and wires are good. make sure the cam sensor is put in properly and position.

NO Start the truck is not getting spark the coil is good but i'm not getting any power to the coil and I need to know if i'm testing it right i'm thinking it is the ignition


THE POWER TO THE IGNITION COIL COMES FROM THE AUTO SHUT DOWN RELAY..THE AUTO SHUT DOWN RELAY IS GROUNDED BY THE POWERTRAIN CONTROLLER WHEN IT SEES CAM AND CRANK SIGNALS..WHEN CRANKING..HOLD YOUR TEST LIGHT ON DG/OR WIRE AT COIL AND HAVE SOMEONE JUST TURN KEY ON..YOU SHOULD GET POWER FOR 2-3 SECONDS..IF IT DOES,THE CIRCUIT TO THE COIL IS OK..CHECK ALL FUSES..FUSE 9 IN JUNCTION BLOCK INSIDE TRUCK,FUSE 3 IN UNDERHOOD FUSE/RELAY CENTER..CHECK FOR ANY FAULT CODES IN PCM..YOU MOST LIKELY HAVE A FAULTY CAM OR CRANK SENSOR..CAN BE MONITORED WHILE CRANKING ENGINE WITH A SCAN TOOL HOOKED UP..LET ME KNOW WHAT YOU FIND

Car cranks but won't start. Diagnostic code says


I changed all the parts I mentioned and finally I decided to try the crank shaft sensor and if that didn't work I was going to replace the cam shaft sensor. Luckily the crank shaft sensor worked but only after I replaced all the other parts. But at least now it finally started.

Thsank you.
