our parts delivery truck broke down on the way to make a delivery yesterday and we finally got it back from the service center in working order with the faulty part to show us.



i would have never guessed the pigtail on the inertia switch to be the culprit but i guess ive seen stranger things?

Iv'e seen that happen on a connector once before. It was caused by it not being plugged in all the way and arcing, melted the plug and everthing worked fine after putting in a new connector. $5 part, but took two hours of R/R to figure it out. Lucky for you it didn't melt the harness!

common issue on rangers. i bought one that would randomly die from no fuel, owner worked on it for a long time before he gave up and sold it. took me a couple days to figure it out but it was exactly the same thing you have a picture of!

Who would suspect something that is basically fool-proof to be the problem....

My 88 ranger had the inertia switch short out and melt in it to, took me a couple of days to figure out why it would die randomly.

That's what happened to my Tempo...and the guys replaced the engine (eventually), the transmission (because they didn't know how to pull it and it collapsed), and my in tank fuel pump...and when I finally drove out of their garage $2,000 poorer (my Dad paid, actually) the car drove fine all the way home (except a new wobble that it developed when a meathead mechanic decided to test his ball peen hammer on my rotor to see if it would relieve his frustration after the tranny collapsed) and it would not start...

Total cost of actual problem = $35 for the inertia switch...

That is when I decided to work on cars myself and leave the ball peen smashing to someone else vehicles...whenever possible...

x2. partial/dirty connection = lots of resistance and with a decent amount of current (inertia switch switches full current of fuel pump), that equals lots of heat. had it happen on the 3 big wire connector by the battery (the one that wraps around the front of the engine compartment for the fp, rear defrost, and something else i dont remember)
