01 Dakota 3.9l cranks but won't start
The following parts were tested for PCM voltage and signal:
. Crankshaft position sensor Camshaft position sensor
TPS MAP IACThe following parts were tested for B+ voltage with the key in on position:
. All injectors Ignition coil primary
At my wit's end here guys, please any suggestions, advice or information on will be greatly appreciated

What are you not getting? Spark, or fuel? Need to test for injector pulse as well. You can like rent a fuel pressure gauge, and noid light (to test for injector pulse) from your local parts store.

Welcome to dodgeforum...
Pull the plugs and see if they are gas fouled... if yes clean them up with brake cleaner and put them back in.
Test the coolant temp sensor & verify it is at the approximate value for the coolant temp which would be dependent on where your at and ambient temps. Figure it should be close to your ambient temp since its been down for a bit. Service manual, download it from the sticky above, should have the temps in it for the CT sensor. If not, google coolant temp sensor and have a look at the images that are returned, they should be in the ballpark.
If that checks out, get some starting fluid, pull the air hat off the throttle body and have someone hit the starter while you give it a shot. If it fires and dies then you know it can at least fire up.
How many miles on the motor?
3 cats or 1 cat?
Any engine codes?
