how do we check for the pulse out of ecm pin 57 and pin 59 ----2006 dodge ram 3500 5.9 cummins diesel codes are p2149 and p2146 engine starts and runs for about 2 seconds and dies if you turn the key when it dies turns over but nothing but if turn key off about 10 seconds it will run again for 2 seconds and same. have checked most everything else I think its gets pulse from ecm first 2 seconds but what should it be on pin 36-46-56-30-40-50
JA: Is the car in "Park" or "Neutral?" Do you know if your car has a "wheel lock" feature?
Customer: this is a 6 speed manul
JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: truck ran good had fan wire cut issues but truck ran good so sent ecm to be fixed and they said they found no problem and we sent back ecm because truck had these issues after we put ecm in they told us it was a security issue so had a dodge tech come re program keys and same issues and we have checked all wires to and from ecm and probably anything else a shop can check fuel pressures rail pressures turning engine over filters about everything but please ask checked pulse at crank shaft sensor cam shaft sensors vistronic fan clutch
wires all pulse and 5 volts were as it supposed to be and probably more but please ask me if you think of something but I think it looses the pulse after 2 seconds at ecm
JA: I'm an assistant to the Dodge Mechanic. I work with them to help customers like you.
Customer: yes I read a lot of your threads and there great
JA: Anything else you think the mechanic should know?
Customer: we are a shop and had different guys on it and I'm thinking the people that worked on ecm may not be as good as we hoped
