Hello and welcome to JustAnswer!

It sounds as if you have a PCI bus communication issue. If the SKIM module can't communicate with the powertrain control module then it will start and die, and you'll have gauge issues and warning lights if communication isn't possible.

Can you explain exactly what you're seeing on the instrument cluster?
