2002 Dodge Dakota not starting help please!!
My dodge dakota is not starting. The motor turns over but will not fire. It is a 4.7 with individual coil packs on each spark plug. Also the gauges are non-responsive. No fuel and no spark. Gauge test/reading brings up a 920, 921, 999 code on the odometer. Also says "no bus" on the odometer. check a few places and was told to try the crankshaft sensor, no luck, checked the input voltage to the crankshaft sensor and its still 5 volts. Input voltage to the camshaft sensor is 5 volts, tried with camshaft sensor unplugged no luck. PCM is receiving 12 volts positive from ignition. Switched engine relay with blower relay, no luck either. Looked for an Auto shutdown relay cant find one at all. Can anyone shed any light on what to do next. What to test next, how to test it?? Cause i'd rather not go straight for a PCM and then have to pay the dealer to get it programmed with the vehicle vin and odometer. Would anything happen if i didnt get the new PCM programmed?? Thanks in advance for any help.

go to a shop but fix at home
Can you get it to a shop most will test for free then on their recommendation go from their fix what they say needs done THAT DOSNT MEAN THATS THE PROBLEM but it’s a start shops are just as clueless about things as you but it’s a second opinion.
Can you bypass the individual coil packs on each spark plug they may be a start to understanding whats up bring the car back to stock I have never been a fan of performance ad on parts they can cause problems at later dates. If these are stock then forget what I said
Were you changing anything in recent weeks on the truck installed something new?
Can you crank it with a sparkplug out and see if its sparking, spray carb cleaner in the air intake with filter removed as its cranking to see if you get something out of it?
Just do some of the basic system checks.
