Frequently Asked Questions
How do I know this relay failed?
Stalling on deceleration or a fuel-cut fault points here. Swapping it is a quick, low-cost first test.
How do I test the fuel cut relay?
If the truck stalls on deceleration or runs on, swap in a known-good relay - relays are cheap and quick, so this is the first low-cost test before deeper carb work.
Is it safe to just swap the relay?
Yes - relays are cheap and easy, so swapping in a known-good one is a sensible first test before deeper carburetor diagnosis.
