Swapped the relay still no start so next step was new relay still no fire. Went next step and bought new ipdm and still will not start thing is driving me nuts! Thanks for any info in advance.

Have you done the fuel pump recall? Possibly the gauge is showing fuel and you really ran out? Or a fuel pump burnt out? Start diagnosing. You need 3 things in order for a vehicle to run. Fuel, Air, and Spark. Check those 3.

There was a fuel sender recall on those. You might actually be out of gas.

Edit. I see CV was already here.

We ar talking the engine fan right ?

If so ,that ain't good.

The truck is in whats called CAN (Control Area Network) system failure. CAN failure happens when one of the numerous control units on the network fail (stops communicating). The system goes into fail safe mode and fan and or lights are on all the time.

The fun part is trying to find out which control took a dump.

Common culprits are ECM , TCM and ABS .

Bottom line, it's going to get expensive.

Does your obd port have power? It could be just a fuse keeping you from communicating with the Ecu.
