It's rare, but I've read that it happens. Once you've got your FP assembly out of the tank carefully examine your pressure regulator for any cracks. I suggest you find that thread and read them. I recently (last week?) posted some time/aggravation saving tips on dropping the fuel tank and changing the fuel pump. The only things you need to purchase is a new pump strainer sock and a new fuel pump, unless you just replaced your filter. You will not need the large O-rings and one of the pump insulators. The nice thing about the Bosch 69128 kit is that it comes with enough submersible fuel line to replace both pieces (pump-to-FPR and FPR to fuel line) several fuel injection-style hose clamps, a new pump insulator and the thin-to-thick terminal jumper wire (which you'll need). All my OE pumps started having issues at between 175k-200k, which seems to be their average life span. However we've logged well over 100k on the Bosch pump (on 6-7 different Explorers/Mountaineers) with no issues whatsoever.

Ford has released an updated replacement fuel pump driver module that comes with a kit to space the module away from the frame. Symptoms can be a P1233 Fuel pump Driver Module (FDM) Offline. After time the corrosion will eat a hole through the aluminum housing and allow water and outside elements to short out the electronics. Early model trucks attached the aluminum driver module directly in contact with the steel frame. Trucks equipped with a 5.4L Triton 3 valve engine uses a module to control fuel line pressure by pulse width modulation of the fuel pump. Early models of the 2 valve would blow plugs out of the cylinder and newer 3 valve engines tend to break plugs when removed.ĭepending on what state you are in you may experience fuel pump issues. Keeping new plugs and coils installed and 50-75k mile intervals is cheap insurance for your engine.ĭue to the heat from the coils and a specialized spark plug Ford has had a slew of issues with the plugs. You may notice a jerking or bucking that can be mistaken for transmission issues. When a failure happens you may experience cylinder misfires especially during accelerating or around 50 to 60mph in overdrive. Another issue we see is oil or coolant can make their way into the boot and that will affect the performance of the coil. Preventative maintenance of plugs and coil boots can ensure no issues arise, the rubber that covers the spring at the coil output prong to the spark plug can deteriorate with age and weak spots in the rubber can cause the spark to jump to the plug well instead of the spark plug. The design is very efficient but can lead to excessive heat. Each cylinder has a separate coil that fits onto the spark plug. The 3 valve 5.4L Triton contains a coil-on-plug design. The most popular issue but easiest to fix, is the ignition system.
Most of the most common problems developed with the 2004-2013 3 valve engine but some problems spanned all engine generations. Ford’s flagship V8 has been around since 1996 with the 4.6L that led to the 5.4L.
