i was driving my truck and it quit just like i turned off the key. i had it towed to a dealership but they are closed for the long weekend. some symptoms are: the antitheft light is flashing very quickly when i turn the key on and normally it goes out. Also the speedometer just shows a row of dashes no numbers. i can hear the fuel pump run when i first turn on the ignition. this unit has an aftermarket remote start system but i disconnected it while waiting for the tow truck but no luck. anybody have any ideas. thanks

 

Does it cranks? if it does and no start it can be just 2 things fuel related problem ignition system problem easies think to do is run a diagnostic to see if it store any codes and go from there good luck.
