Typically, you’re looking for around 12 volts at the pump. If it falls significantly below that, your fuel pump driver module could be the issue.

I’ve also read that intermittent issues can make diagnosing this tricky. Sometimes it’s fine, and then it suddenly fails! Any thoughts?

24

That’s frustrating! It could indicate a loose connection or a failing module. Visual inspections can help too.

I think we need a new diagnosis manual just for these fuel pump issues! It’s like they have a mind of their own. :thinking:

Ha! True! But seriously, keeping the connections clean and checking wiring can go a long way in preventing issues.

Common symptoms include engine sputtering, difficulty starting, and stalling. If you’ve noticed any of these, it’s a good idea to investigate further.

It’s always best to check the electrical connections first, as they can sometimes cause headaches without needing a full module replacement.

36

Good point! I never thought about that. What are some DIY steps for checking these connections?

37

You can start by inspecting the wiring and connectors for any signs of damage. A multimeter can help test for continuity as well.
