I decided to take a look at my Fuel Pump Driver Module after reading on here how they corrode and become defective. As you can see in the pics, mine is fairly corroded but doesn't have any holes or anything like that. However, here's a list of recent things I done to tune up my truck(in the past 2 months) and the motor is still missing at times.

New Spark Plugs
New Ignition Coils
New Throttle body
New fuel filter
Cleaned MAF
Re-flashed the PCM
Had Catalytic converters tested(were totally fine)
New seal around bottom of air box
Transmission flushed
New rear axle gasket and fluid
New Vapor Canister Purge Valve
New vacuum lines

So I can rule out quite a bit except for the FPDM. My truck randomly doesn't start right away, like it's starving for fuel. If I lightly press the accelerator I can get it to start. It also misses and makes an engine moan at low speeds below 2000 rpm and at 50-55mph. So I'm thinking maybe to replace this. What do you think?

 

REPLACE IT. You pretty much answered your own question. That FPDM is the old style and is a ticking time bomb. Best change it before it leaves you on the side of the highway. They're not expensive.

 

Wednesday I went to drive to my class and ended up breaking down. The edge programmer said something to do with fuel pump, after being towed to the dealership. They said my fuel pump module cracked and water got into it. So needless to say I just replaced mine lol.

 

Yeah I figured I'd better replace it with so much corrosion on it. I found a brand new one on ebay for $59 so I'm going to get it. Man, I really need to get an Edge programmer. They let you know everything that's going on with your truck!

 

and you need to mount it better than the stock one your replacing....try level 2 on your Edge...

 

Replace it asap.
I had mine go with no warning, 310km tow to the dealer, cheaper to replace it than tow it in. Ya edge l2 is good for me i don't want to run 91 oct.

 

Not sure if addressed to me, but I am running level 2 on my edge.
