If this isn't a PATS issue then who knows what it could be. He said the fuel pump isn't coming on. I've heard/read different opinions on how the PATS works. Can the Gryphon override the PATS?

I don't know how the PATS works either, but I wouldn't want to override it.

There is a component though, in the instrument cluster that "senses" the PATS key and it is an integral part of the instrument cluster. Just off the top of my head, I think the mechanic needs to get the instrument cluster from the vehicle he got the engine from and he needs to replace yours with it. This "receiver" cannot be obtained separately as I understand it. I hope the newer instrument cluster will fit!

This issue has been discussed several times in another forum when the subject of swapping instrument clusters has been brought up.
