590-001 Fuel Pump Driver Module with Mounting Bolts

Me salió muy bien lo puse y funcionó muy bien solo que hay que poner con el switch cerrando si poner la llave, quitas el módulo viejo y pones el nuevo lo conectas y todo bien fijado y después ya abres el switch y va prender la bomba como por 3 segundo y pues es lo único de ruido que se puede escuchar arranca muy bien

I own a 2004 Ford F150 FX4 5.4L Triton that has always had a sporadic slight hesitation on acceleration since I bought it used. From my decades of mechanic knowledge, I thought it was fuel related but never could pin it down. The engine bit the dust because of timing chain and I changed just about everything when I replaced the motor. Filters, plugs, coil packs, and cleaned injectors. Motor ran good but still had that hesitation in it. I replaced the fuel rail pressure regulator , nothing changed. I looked on youtube and I found a person talking about this fuel pump driver module. It is right about the spare tire in the rear axle area. I discovered what others have found, due to being exposed to road elements, the cast body of the module corrodes and affects the computer board on the inside. For $21 , it fixed all the acceleration problems I was having, now my F150 runs like a healthy 8 cylinder with plenty of acceleration! So, if you are having hard start, hesitation on acceleration or fail to start problems, consider buying this very affordable module to see if it is your problem. Easy to replace, drop the spare tire, push in on electrical connector and pull that loose. Then use an 8mm socket on 1/4 ratchet to remove the two bolts. If they are hard to turn, take it slow. Turn till they get tight, spray something like PB Blaster around bolts, retighten to work lube in threads, then start loosening again. Take your time, you dont want to break them off in the frame. They will come out if you take your time . I wouldnt use the new bolts that come with the new one. Just clean and lube your old ones.

Never even realize that this part was a thing but it came with all the parts I needed in order to fasten it to the body of my car because the original bolt holes were rusted out but this manufacturer thought well ahead and sent other boats for other bolt patterns to be able to fasten it in its position Great quality great price easy to install and very functional

I bought this for my 2006 Lincoln Navigator. It looks and fits like the factory product, and on this vehicle, it is pretty easy to swap out. It didn't fix my issue, as I guess I need a fuel pump replacement, but it hasn't given me issues yet. Will update the review if that changes. The included spacers to help prevent future corrosion issues is a really nice touch, especially for the price of the entire purchase.

So far so good! Before looking into a fuel pump this is the item to check out if your truck isn't getting gas. New module worked great! Much better set up then the old one (which was broken in half and crumbling). Aluminum and iron don't mix. The rubber spacer should work great in this module. We'll see how it does longterm.
