That may be the problem...... our trucks don't like aftermarket sensors in critical areas...... crank sensor being one of them. You could try another one..... or spend the big money at the dealership, or maybe find one from Ma mopar a bit cheaper online somewhere.....

 

anyone know how to check the snyc between the cam and crank sensors?

 

Need a scanner.

 

Did you say it goes fine in reverse??
