yes it was a oem module
fuel gauge worked fine the the pcm B fuse blew and the pump stopped working I replace the module with a oem module the the gas gauge was not working so i put the old sending unit on the new module but it did the same thing. no i did not replace the connector that plugs into the module
so i have to drop the tank?
i have replaced all the stepper motors. could the fuel pump have burrned up something when it blew?
i have a new programmed pcm the harness to the tank looks good. can a fuel pump burn up the pcm?
so almost everytime i start the truck it will go to 1/8 to 1/2 tank of gas for 20 sec then drop to E and the low fuel light will turn on .....I restart the truck same thing .. ok so set the ohm meter to like 200k and check the reading across the purple and black wire? what are the wires at the pcm?
ok let me pull the cluster and swap the stepper moter
ok I got it. the plug on the new oem module was bad. I put the old plug in the new module and everything works. It was making a connection (hence the good ohm reading) but not good enough to support the gas gauge.
thanks for all your help
