I tuned my truck with an Autocal back in April. The Autocal had the wrong VIN number from the tuner. Me not knowing any better I tried multiple times to flash the tune. It fried my ECM. I bought a used one and changed the VIN number. It got me up and running. Now 2 mos later the truck developed a rough idle with no symptoms other than that. No hard start or smoking. I drove to work and now won't start. The injectors check out in every way. CP3 pump is good and putting up 7200 psi. I've had the injectors pulled and sent for testing. I'm concerned about the used ECM. It doesn't make any since at all that every thing on the fuel system seems fine but truck won't start. Is there a way to recover my original ECM? If I buy a new one for 3000$ I'm worried about damaging it. If I get a new one would it have different serial number requiring me to purchase another license?
