Inertia Switch - 2005 Ranger

Geof · 2005-09-24T11:48:57+00:00

I have a Ranger that I got in February of this year. We have had acontinuing problem with the Fuel Pump Shut-off Switch (Inertia Switch).The switch has "tripped" several times since I got the truck. A fewweeks ago the dealer happily replaced it, it promptly "tripped" again,and then yesterday the truck stalled in traffic after crossing oversome rough pavement and the switch tripped again.I called and scheduled it to go into the shop next week to have theswitch replaced again.Somehow this seems to me to be a fairly important and safety relatedissue. While driving the truck at speed and in traffic the enginequits without any warning. This has happened to me on the highway athighway speed too.Has anyone else had any issues with this? Are there other places tolook to rectify this problem?Thanks in advance - Geof

PRAISE !!!

I hadn't heard of vapor lock since the 60's.

Would've thought the right elec. pump and a larger diameter line would've covered the FI, VL bases ...

As usual, I Believe Every Word they Say. The Ford inertia switch has been an industry orphan for 11+ years ...

Much thanks to aarcuda69062 for some very interesting info.

There's nice guys in this forum. They don't wanna hear me rant. So I won't.

But nowadaze it's easy to create your own bumper sticker. I'm gonna get started on mine today:

It seemed to go off while getting onto interstate entrance and merging onto the interstate a lot. I could be driving through a normal intersection and hit a bump where the concrete slabs aren't even. It took the slightest bump the times it did go off. I never did figure out what was going on. I finally just temporarily locked the switch in the "running" position and never had another problem.
