I went on GM Parts to try to search for a part anywhere in the US and evidently it doesn't work like that. You have to put in a Zip Code and you are referred to a GM dealership in that area... Which you find out does not carry the part. I called numerous dealers and was told they have "X" number of vehicles waiting for the part. I then called GM Parts and the Customer Service Representative told me me they cannot do a global search accross the US.
I was then transferred to a Case Manager that is trying to help me with my situation. I explained to the CM that I have two major concerns... First, based upon the number of vehicles affected by faulty Fuel Pump Control Modules, many of which have very few miles on them, what assurance do I have that if/when I do get the part it won't fail in 5k, 10k or 20k miles and I'm in the same situation again. Second, from my research this part is still being used in various GM models. How is it they have the parts for production vehicles but not their Loyal Customers who now have a $45k and up Paperweight.
I Googled GM Part Number GM 13540028, checked on Rock Auto, etc and from what I can tell it's a GM exclusive part with no aftermarket support. That said, I found 74 GM 13540028 for sale on ebay. Some showed shipping from the US while the majority shipped from China. The prices ranged from $70 to $370 with most being around $100. I messaged about a dozen vendors asking if the part they are selling is a GM OEM Part and every single one replied that it is an aftermarket equivalent part. I watched a couple videos and from what I saw a Fuel Pump Control Module has to be programmed and who knows if the ebay part would even work. Then again, I wouldn't be surprised if the GM OEM Part was made in China by the same company making the ebay part.
I'm half tempted to order the ebay part and ask my dealer install it. My guess is they would refuse and even if they would, would it program correctly. Then again, could it be any worse than the GM OEM Part. It's very frustrating when you pay for a vehicle and it doesn't work... Not to mention your told there is no ETA for the repair part. This is my 4th GM truck, the other three had 250k miles or more when I traded them without any major repairs. This one may be my last.
