Le problème peut être dû à la valve IAC car cela régule le ralenti, mais si vous voulez une pression de carburant.
The case of the fuel filter discarded it since if it were covered it would not start in any of the cases but as you say that you are still in it (in the truck), so I discard it, as with the air filter since the ECU regulates the fuel to be supplied in the air that enters the engine (mathematical calculation processes of the ECU) and in that current case the IAC to regulate the minimum march (Ralenti)
