bad fuel pump module

Justin Milton · March 30, 2022

Both myself and friend of mine own a 19 Silverado 1500 (RST and Trail Boss). Same exact issues with the Fuel Pump Module. GM needs to eat this one and put a bulletin out to repair a known defect.

Sounds like a lot of guys real frustrated with this issue.

I’ve given up on dealers.

buy the part off eBay and replace yourself. Two screws and one clip….. very very easy

2020 Chevrolet Silverado RST 4WD 5.3 V8 Fuel Pump Control Module Failure less than 20k miles.

Dealer said may be a month and is renting a car for me but wants me to kick in on the cost.

Not happy about this at all !!

Buy the module and do it yourself. $50

Took 6 weeks to get the part for mine, then another 2 days to install it. Ridiculous.

I am having a similar issue however my code was a P0498 EVAP emission system vent valve circuit low. Replaced the vent valve solenoid but still had light. Replaced the purge valve solenoid but also still had light on. Took it to the dealer and they say the fuel pump flow control module needs replaced but is on b/o. Waiting to hear when they think it might be in. Seems to me $500 is a bit steep, isnt it mounted on the side of the frame?

Is there any reprogramming necessary afterwards? Should I disconnect the negative the battery while swapping out the part?

Must be a bad batch of modules or something.

Just purchased a brand new 2022 GMC Sierra 1500 Limited with barely 700 miles. A few days ago, the Service ESC, Check Engine, Engine Power Reduced and StabilitTrak lights came on! Took the truck to local Chevy/GMC dealership and was told that I have a bad fuel pump! Part is on order (May 11th 2022) so let’s see how long this will take -_-

May 13th got my truck back in full working condition! Turns out that it was a bad fuel pump (on a 2022 truck!)

I just had the exact same thing happen on my 2020 HC. It is at the dealer now and they don't know how long till the parts come in...

Has anyone had a second failure?

I Have a low pressure fuel pumpproblem as well on 2020 silverado 5.3

Covered under warranty but part is on "national backorder". 2 previous versions of the part but waiting for the 3rd version

5 weeks later still waiting on part.

Any one have similar problem?

My 2020 Trail Boss has been in the shop several weeks now. The fuel pump is bad according to the technician. Fuel pumps are on national back order according to customer services. They don't have any idea of when the part will be in. I am very upset. Customer assistance offered to pay the truck note, but I have to pay the tag and insurance ($250 per month). That can get expensive fast on a vehicle I cannot even drive. And I am worried about the income tax ramifications of them paying the note. At some point doesn't the lemon law kick in? I am seriously over this truck.
