T56 speedo works untill car is shut off then notta on restart? help!
I hooked up the Dekota Digital interface unit, reset my ecm, and it works perfect untill I shut the car off. As soon as I restart the car, with out even moving the car, the ecm throws a code and the speedo no longer works. Reset the ecm, and it works again untill I shut the car off....... Has this happened to anyone else?
