My gauges speedometer,fuel, tach and temp stopped working as did dashboard lights also car turns over but won't keep running . Is this more then one issue or could vat key be to blame

Hello, it honestly sounds like an electrical power issue, such as from a battery / charging system that does not have sufficient amperage or voltage to power the various electronics of the vehicle -- including the engine's processor. It's a totally wide open guess, however, without hands on inspection and doing a little rudimentary troubleshooting. Best I can do is suggest some shops near you: www.repairpal.com/repair-shops
