2004 ford f150 fuel pump driver module location
We can share a few photos and keep on talking. Overall components, it kind of changes things around, but, again, overall, for fuel efficiency, as well, it helps out, because you're not trying to deal with so much fuel pressure. More efficient use of the electricity of the vehicle is really what it is.
In idle, for instance, you don't need a lot of fuel.The pump is really there to deliver everything under load, so they put this driver module in, and what it does is it lowers the voltage to the fuel pump.

A lot of times, you don't need that full on 12 volt energy and pressure that a fuel pump delivers. Somewhere, automotive engineers are looking at what it takes to run a vehicle, how much energy is being used just to pump, just how much electrical energy it takes to run a fuel pump. It's probably been around for about 10 years. What's a fuel pump driver, and why do they use it?īernie: It's a relatively new component.
What we found when we finished, complete our diagnosis is that the fuel pump driver module was dead, and that was causing our fuel pump issue. As a matter of fact, probably about 95 percent of the time, it is a fuel pump, but, in this case, Ford has a little more complex system that adds to the fun of the diagnosis and, ultimately, the cost to the client to fix it, as well. Mark: No fuel pressure is usually a dead fuel pump, right?īernie: Well, usually it is. All the other components needed to make an engine run were there, just no fuel pressure. Basically, that was the reason it wasn't firing a good spark. Of course, the battery was almost dead, so we charged the battery, hooked up some testing equipment, including a fuel pressure gauge, among other things, and found there was no fuel pressure. Very common arrangement.īernie: We diagnosed. Yeah, a gas engine, 5.4 litre, I believe, in this truck. Mark: Being an F-150, I assume it's a gasoline engine.īernie: It is. Eventually went to go start it one morning, it just cranked over, but nothing happened. It wouldn't stop, and the owner's complaint was that it had been getting progressively harder to start. What was going on with this truck?īernie: This vehicle was towed to our shop. Mark: We're going to talk about a recent repair of a Ford F-150, a 2008. 16 or 17 times, we're not sure yet, I think it's 17, Bernie thinks it's 16, time winners of Best in Vancouver as voted by their customers.
