A few days after a snow storm, I decided to be proactive and take out the garden hose to rinse off some of that damn road salt and magnesium chloride. Common practice of mine. But then, I get in to start it. It just turned over but wouldn't start, even after several hours of drying time. I thought I tried everything, but then I crawled up underneath the bed where the fuel pump control module is mounted on the frame cross member just in front of the spare tire location. The module was rotted and broken in half. Exposed and corroded circuit board, hanging from its wire harness... pitiful. Bought a new one from napa, plugged it in, and started right up.

So I guess if you drive through nasty slushy salt I'm the winter, it may be worth dropping the spare (if that's not rotted too) and taking a peek at this part.

 

Replaced mine last weekend. The case was starting corrode.
Since then the truck has been accelerating and idling a lot better.
Mine must have been going bad because replacing it made a big difference.

 

I know everyone has their own preference for brands but what are the majority of you guys replacing your fpcm with?

 

I believe my replacement was the NAPA brand. Not sure about the others, but mine came with rubber stand-offs, I assume to minimize the collection of dirt and salt between the frame and the fpcm. A good improvement IMO.

 

Hi.

First choice - Motorcraft.
Second choice - Dorman.

Important thing is to mount it using standoffs.

Best approach? Raid a parts truck at a wreckers for the harness, and the connector on a bad FPDM. Make an extension harness and mount the new one inside the cab behind the rear seat - with no standoffs as you want to use the rear cab sheetmetal as a heatsink .

You'll Never have to worry aboot it again. And if it ever does go south, it will be cake to change ( throw a spare one into yer existing onboard emergency spares cache ).

Yeah - I'm a big believer in redundancy and carrying spares for everything within reason.
