In July my car said I had no gas but I knew it was full. Mechanic said both fuel pumps were failing.

Next day, check engine light goes on. Hose wasn’t calibrated correctly.

A month later gas gauge isn’t registering correctly again. One of the new fuel pumps failed. Probably damaged in shipping.

Gas gauge still isn’t right. The mechanic had it for over a week before deciding it is a float in the gas tank. Claiming $2600 in additional parts.

What to check next

Diagnostic guidance. Suggested checks and possible repairs are separate from the owner's reported results.

Request the invoices, installed part numbers, fault codes and test results from each visit. Ask the shop to distinguish a fuel-delivery problem from a fuel-level reading problem; components may share an assembly while performing different jobs. For the gauge complaint, have the applicable sender readings compared with the displayed level and inspect the relevant connectors and wiring. Confirm replacement-part fitment using the VIN before buying another assembly. An independent diagnostic review is reasonable if the explanation remains unclear. Do not rely on the gauge until its operation is verified. A documented test of the sender-to-display path can turn a repeated parts-replacement problem into a specific repair decision.

I’ve only paid for the original repair. I only asked about price because I assumed it was cheaper.

Are they trying not to give me any money back. could they have caused the extra damage?

YEs, the job they did may not be correct. I would take it to a different shop but tell them the story so they can check it out. Does the car have any codes? I would do a CAN scan to see which codes are stored, this will give us an idea of what the problem is. Please go over this video.

Thanks for the response. I’ve been fuming with all of the run around and issues over the past month after the botched first repair. I was pretty sure it was misdiagnosed and they were the cause of the later problems. Now to prove it and decide if I am filing more complaints.

Hopefully getting my car back Monday or Tuesday. It needs to sit 24 to 48 hours after the repairs they performed. I’m pretty sure there has been something going on there and I’m planning on asking for all of the diagnostic reports. When I asked for them from the first repair they told my they are archived, so we’ll see.

Yep, sorry about that, car repair can be a frustrating experience. Like my grandmother would say, this too shall pass. So hang in there and let me know what happens.

Discussion summary

Car said I had no gas but I knew it was full?

The owner described a fuel gauge reading empty despite a full tank, followed by repeated shop visits and reported pump or float-related repairs. A warning light and further failure reportedly occurred afterward. The owner questioned the diagnosis and expense, but invoices and test results were not supplied.

Reported outcome: No lasting repair or independently verified cause was established.

The number and identity of the replaced components, quoted costs and explanation about calibration were not verified. The discussion does not establish misconduct or responsibility for the failures.
