On a different video, this guy was mentioning everything that could go wrong with the fuel pump but didn't address the simplest test. Thank you. You saved me so much money.

Thank you so much for posting this video! My 1995 Mazda B2300 suddenly wouldn't start and I suspected the fuel pump had failed. But this video showed me that it was in fact just the inertia switch. It was such a relief when the truck started! Anybody else out there with a Mazda B-series truck would do well to check this switch, too.

THANK YOU SO MUCH! I was just about to buy a fuel pump for my 2003 B2300, but I saw your video first!

Thanks for the reply
I'll have to look into that .
I also got from a mechanic that it might be a skipped timing belt . Thanks again

My son had his front passenger tire blow out on his '03 XLT, then the truck wouldn't turn over.

Checked the fuse and the relay, looked for the driver module and realized it's in the tank on an '03. Truck isn't worth dropping the money into a fuel pump and labor. We were getting ready to have it hauled to the junkyard until I stumbled across this video. Pushed in the button and the truck fired right up.

Liked and Subscribed.

Does running out of gas affect the inertia switch on a 1986 for Thunderbird, 5.0??

[kennyplay]

I had small front end collision 2002 Ford mustang. Recently, fixed parts. Car kept starting, I could drive it. A month ago though, I had trouble starting, cranked, and eventually started. Like no gas. But yesterday it didn't start. Cranked, but no start. Is there an inertia switch in the front? Thank you

Hi, I have a 96 Ford Explorer, We broke down about a week ago, The mechanic where we broke down said it was the fuel pump that it was dead, The car wants to turn over but just wont, We replaced the Fuel Pump and Filter on it but still it wants to turn over but just not doing it, Do you think this switch might need to be pushed ? There are a lot of pot holes in my city.

[maddmarkstevens]

Can I manually over ride the button simply by crossing the two wires on the plug in adaptor for the fuel reset button?

[pistolz]

sir. i have a 93 ford escort that reads 8 volts at the wiring harness for the fuel pump. my inertia switch seems fine. what could be the problem. the car battery is good

[JUSONTHEBEAT]

Lol WOW! Video was extremely easy to follow. I don't know wtf some of these comments are about. Thanks for the vid!

[billrhodes]

My 2019 Fiesta ST does not have the inertia switch behind the glove box. Or, in the passenger kick panel. Wonder why they decided to put it elsewhere?

[tannervermillion]

Saved me having to drop my tank out and replace my fuel pump. Thanks

[dads]

is the inertia switch for a 1997 taurus in the trunk or pass. kick panel?

[KingDB]

So the switch is supposed to be pushed in..?
