Does not attempt to fire, dash lights up, fuel pump does not turn on. We have replaced the ignition key module and it has not solved the issue.
You have a bad ignition issue. It’s more than likely a module. This can be found in steering column.
Are you referring to the ignition relay switch?
How do we get to this piece?

Sounds like a bad ignition key module. Should be on the steering column hidden under some trim.
Are you referring to the ignition relay switch?

Yes. Try swapping fuel pump relay with AC or door lock relay.

If the key is returning to the 'Run' position as it should, then either a relay controlling the solenoid or the solenoid itself is hanging up. The heavy contacts that send power to the starter can develop rough surfaces that can temporarily weld themselves together causing the starter to run on even though the engine is running and the key has returned to the proper position. There is also a spring that should normally help return the solenoid's contacts to their 'off' position that may be weakened.

Was the old fuel pump bad? It might be worth the cost to replace the ignition switch. The wires to the fuel pump would be a second guess if the old pump was bad and burnt the wires before the fuse went. When you eliminated the fuel pump you also eliminated the wires to the pump and it started. Then you replaced the pump, but not the wires. The ignition switch is the other end of the circuit.

Yes, it sounds like your solenoid is bad and staying engaged against the flywheel, you could do an amperage draw and a voltage drop test to find out for sure, but you will need an DVOM and a amp clamp. Or you could take it into an auto parts store and they will test it for free. Hope this helps.

try cleaning the connector that goes to the fuel pump, sometimes they corrode on inside. If that does not fix, test the wires feeding fuel pump with a multi meter until the condition shows itself again, if voltage drops to zero or very low then wiring problem, if voltage is unchanged with problem and fuel pump is not working and connectors are all clean, try replacement of fuel pump.
