F250 5.4 triton v8. Starts for a second then stalls. Tried cleaning throttle body. I cant locate the iac or thegr valves to clean them. Any Ideas?

 

Weak or bad fuel pump. Maybe?

 

No IAC, it's electronic throttle.

Check your FPDM for corrosion on the backside or in the connector. Don't know where it is on a 250, but on a 150 it's on the crossmember above the spare tire.

 

I hope that MGD is paying attention!

Really dirty fuel filter, weak fuel pump, or maybe even water in the gas.

Like they said visually check the FPDM. Then go for the fuel pressure check, I think you need a scanner for your year truck. Plus if the fuel filter hasn't been serviced, it could be time.
