[Joe Maxima]

Anyone have any experience with ECU upgrade from JET Performance Products out of Huntington Beach, CA? I just received the ECU from my 2002 Maxima SE back from JET after paying to have it upgraded ($399 plus shipping) and when I reinstalled it into my Max, the engine would crank but not turn over and start.

I followed JET's instructions carefully i.e. disconnected negative battery cable before removing ECU, not starting car while CU was removed, etc. but I don't know why it won't start. Any ideas?

I am contacting JET tomorrow to see if they can trouble shoot the problem and to get authorization to return my ECU so they can see if it's a problem with the programming they did.

In the meantime, my Max is grounded and I'm worried about the possibility of some expensive repairs... Any help would be appreciated..
