Installed chip and new PCM and now won't fire

[04sblightning]

Hey guys, so the previous owner cleaned the j3port to where copper was showing so I got a remanufactured PCM and when I try to start the truck it went fire. Turns over just fine but won't fire. Wait to start light stays lit through the whole process and won't go off. Thanks for the help

I had this happen to me with my banks stinger plus chip. You have to match the code of the new pcm to the chip manufacturer. For example mine is VDH-5 I thought it was vdh-4 so I sent it back to banks and reprogrammed to a vdh5. If there is no chip on the truck make sure that the pcm is plugged in good enough. Hope that helps

The PCM is VDH5 and I told beans this when I ordered the chip. I'm going to try it again and see if I didn't plug it in well enough like you were saying.

If that doesn't work here is another idea. Make sure it is a vdh5, I say this because my sticker said 4 and I had to have ford run the scan on it to get the actual number, it was a 5.

Try cranking with just the new pcm. Leave the chip out.

Th OP has a 4 bank chip so it won't matter whether it's a VDH5 or VDH4 PCM if the chip was burned for VDH5.

The Banks is single bank and is the reason you had to have yours exactly as the PCM calibration code.

To the OP- take the PCM back out and look at the gold pins inside the plastic grey connector for any bent pins. Double check the new PCM is the right family. Needs to be a DPC-462 for Federal truck. Let us know what you find.

There are no bent pins and I tried to install the new PCM again and same thing happened. Won't be able to try it without the chip till this weekend to see whether if it's just the PCM or not. Thanks for the help guys.
