I purchased this truck recently. The guy told me the fuel pump, fuel filter, plugs and wires were recently changed. I put a battery on it and scanned it with scan tool. No codes showed. I can hear fuel pump coming on. I cannot start it from key. I bypassed key to solenoid switch them it turns over and starts but runs for a few seconds then shuts off. The key switch okay so hard to to turn to on position. What can cause this problem?

It may be a security system issue, try a reset as battery was replaced. A lot of times this happens when battery is disconnected. also, if you have another key try that not a new key. if still not starting have a mechanic scan for codes see if there is a problem with security system.

Also this sounds like a fuel pump or the crankshaft angle sensor has gone out. When you turn the key to the on position without cranking the engine over can you hear the fuel pump run in the tank for 5 seconds?
