No they are not the same thing. The module is bolted to the bottom of the truck near the gas tank.

Do a Google search for "corroded f150 fuel pump module"

Thanks, I did a little research after I posted that and found out what the part is. Seems like a relatively easy fix. I think, with the help from these posts, I've nailed it down to a faulty fpdm. It would make sense that these symptoms occur when it's wet out if the housing is corroded and water is causing a malfunction. Thanks everyone for your input!

If that doesn't fix it, clean the throttle body and Mass Air Flow sensor. Both are easy, half hour complete job. Search the forums, plenty of posts.

Forgot to add my two cents. So after cleaning maf and throttle I changed out my fuel pump driver module. I went with a doorman one part no 590-001 it is sealed and I did add a little extra rv silicone to the exterior seam on the housing. Truck has been running great. No stutters so far *knock on wood* i am also doing plugs this week since my truck almost 95k. I am adding a photo of the sensor I got and the parts that come with. Just for help and info. Hope this helps. I forgot to take a pic of my old fpdm but let's just say it was messed up lol

Finally ordered the part a couple days ago and it arrived yesterday. I attempted to install it today. The hardest part of the install was getting the lock thing out of the bumper which was frozen up. The old part was in such bad shape it was actually cracked from one side to the other. Haven't had those symptoms since I initially started this post, but from the state that the old part was in I can only imagine my truck will run better now. Thanks for all your help guys.

Your welcome...nice looking FPDM...believe it or not...I have seen worse.

Hello All,

I know this is a bit unrelated but I had a 97 F-150 with similar issues. In all honesty I had probably 4 different mechanics ride with me in the truck and all in all tried a bunch of different things to fix the problem (had a surge at roughly 1500 RPM and what seemed like a shudder at 55 MPH). The only other things I can recommend is 1) changing the spark plugs and 2) Even though it sounds dumb don't run cheap gas. I stopped buy gas from discount places and haven't really had any issues since. Also as a side note its worth the $12 to change your fuel filter on occasion

Read all the posts and as usual saved myself time and money, thanks guys FPDM was issue, truck runs like a top again even at 183, 000 miles

surging
 

Good Morning I am new on here but have been looking at this site for awhile, I have a 2008 F150 5.4 that I had changed the plugs, COP's, cleaned the mass sensor & throttle body about a yr and a half ago because it had a surge going on ran great till recently I of course got the cheap COP"s off the internet so I ordered all Motorcraft and had them install last weekend but still I get a slight surge while driving on the freeway then on occassion it will give a good surge I added Royal Purple to the fuel and recleaned the mass sensor but still the same I am at my wits end with this truck so any suggestions I have no codes or lights had to the dealership they had it for over a week and could not find anything ???

did you ever figure it out?
