My fuel pump is constantly ON even if I hold the keys in my hands......
I have to disconnect the fuse to shut it down .

Anyone has an idea of what I should do ?

Reinstall the fuse....then pull the connection off the oil pressure sender. That should stop the pump from running. If it does, replace the oil pressure sender. The sender is a back up switch in case the ECM or relay fails (to get you home). It will turn on the fuel pump as soon as the engine reaches 4 PSI, and then keep it on while the engine is running. They can fail and keep the pump running at all times.

Im thinking the relay contacts are stuck (probubly arched (sorta like a welder) and stuck in the on position).Try swaping relays to test.

Well I have changed the fuel pump this weekend and it is not problematic anymore.

Weird don't you think ?

I will keep an eye on the relay anyway. It make no sense to me that the fact I simply changed the pump fixed the problem but who knows.
