I cannot get my stock file to write to the PCM. I checked fuses, downloaded the latest HPT before I started.
The only thing I can think of is the header hit the starter pole and arced during the stock engine install, but like I said, no blown fuses so??? All grounds are connected, connections are tight. Software issue or did my PCM take a dump?
I'm trying to over ride a COS if that matters.
It said "Cannot find the VCM" So, I guess it's the truck not the software. I tried the scanner and tuner.
Any fuses I should look for specifically? I checked the cigarette lighter as I thought that was the usual suspect ( I also checked a bunch of others)
Bad ground?
I can rule out low voltage as I had the truck hooked up to a charger when I was trying to upload the tune.
I should add that none of the dash gauges are reading anything except the volt meter. The oil pressure doesn't move when cranking and the fuel. Not sure if that means anything. The message center scrolls through "Low coolant" "Battery" "Low Fuel" when I turn the key to the run position. It really looks like there was a partial Flash and it crapped out.
It was COS5 or COS3 (2-bar boosted) HPT tune in there before.
Now I'm trying to load a stock file for a Flex Fuel "Z" truck, 2002 with Traction Control.
