How do you know it needs a fuel pump? If the arm of the fuel level sending unit is elevated due to the dented tank, then the fuel gauge will incorrectly read that there is fuel even if there is none. Did you try adding fuel to the tank?
In a shop environment, you make the call on replacing both and give the customer the worst possible scenario. If you then drop the tank and find out that the fuel pump is okay, then great don't fit the new one and return it. However, you'd be then losing hours that the customers already agreed to pay, so it's a catch 22. Business is business unfortunately.
@saulgilsenan7320 Yes, I'm familiar with the ethical conundrums of the auto repair industry, but that doesn't answer my question. I only asked in the interest of the completeness of the diagnosis.
Good question, @gabeo9474. I'm glad you asked. In a scenario like this, the pump is often damaged after being pushed up by the impact. While there’s a small chance it might still be working, even if it does, there’s a significant risk that it could eventually fail. As I mentioned in the video, it was the end of the day, I ran out of time and also I didn’t have additional diagnostic time authorized to remove and inspect the pump. Additionally, I didn’t have fuel available to conduct the test you suggested, which is a great approach for concerns like a fuel gauge not moving. However, in this case, the tank was also leaking. Finally, the shop’s procedure for situations like this is to replace both the pump and the tank. I hope this clarifies things, and thanks again for your comment!
I’ve noticed on a couple of no fuel no start cars that the engine sounds like it cranks faster,like when there’s no compression.
Thanks for your input!
What type of oscilloscope is that thank you.
@Authentic60th it’s a one channel scope called Uscope. You can find it at:

@DiscipleDiagnostics okay thanks
