just sent pcm and ecm to rebuilder he is going to check both of them and reflash

no i think the pcm is good my concern is the flash and or the model . to many problems that i did not have with the old computer. trying to get a hold of the company that rebuilt this pcm .with the pcm disconected the truck runs fine just no bat charge. the tach works but no other gauges

can a different pcm be flashed to be used in any truck

took a chance changed crank sensor no change now trans temp light is on its about 15 degrees out side. over drive off light is lit and will not switch every time i erase codes only these codes stay but the rest of them return when i start the truck.

can the ecm be tested, do you think it is the crank sensor giving the tach and alt problems

i have a new crank sensor sitting here wanted to make sure before i used it . it would cost alot to have old one tested then if its bad $75.00 for the new one . also ecm is sending 5v to crank sensor. i unpluged crank sensor and the truck would not start do the sensors read part time or is bad sensor a bad sensor. thought i rulled out ecm because it was sending voltage. ??

alt is controlled by pcm , crank sensor is getting 5 v no shorts to it , alt is not getting any voltage to it checked also no shorts in wire , batteries charged 1 year old - - - Updated - - - cleaned all elec connectors on ecm and sensors and alt is new is their really a evap system on this truck looked every where and still never found it

my old pcm stopped working. i sent it in to rebuild i had no bus. it was not rebuildable so i got a different oneput it in and got error codes.PO113 Intake Air Temperature Circuit High InputP0118 Engine Coolant Temperature Circuit High InputP0340 Camshaft Position Sensor Circuit MalfunctionP0443 Evaporative Emission Control System Purge Control Valve Circuit MalfunctionP0505 Idle Control System MalfunctionP1282 Excessive Injection Control Pressureso i started with po340 and replaced cam sensor.no change with new computer my tach jumps, no alt charge, warning lights flicker really fast. and chimes all the time.traced crank wire sensor no shortsother than that it runs fine
