    my problem is: I have 1994 s10 pickup aind in the morning it will start almost normally, but when i´ll arrived to my job, the pick up won´t start anymore I´ll check the spark current and it has, let me tell you that the pick up have a magnet break current and I can´t find the module or relay to take it off.
    Can you tell me if it can be the problem?

    Why would the fuel pump stay on after you turn the truck off. Mine stays on so I have to disconnect the battery to get it to stop.

The fuel pump relay is only for the fuel pump priming when you turn on the key. After the vehicle starts the oil pressure switch takes over and runs the pump. If the pump is shutting off after the motor is running the oil pressure swith is probably bad. Let me know if i can help you further.

Fuel pump relay for a 1994 Chevy Truck WT1500

The Fuel Pump Relay is located in the Glove Box under a little cover on the upper left side. The Fuel Control Relay is the left relay and The Fuel Pump Relay is the right. To test these relays, swap them and then try to start the vehicle, or blow the horn. If the horn blows then use that relay for the pump and you may at least drive the vehicle where needed! If the vehicle starts, then replace them as a pair.
