missing fuel cutoff interia switch

[PFC Laird]

my 94 2.3 doesnt like to start sometimes like the inertia switch has been set off. i've had a dozen people tell me about the inertia swtich, but i can never find it. Finally the last time it did it (as always) somebody informed me of this switch and i asked them to point it out to me. He pulled of the kick panel and it wasn't there. odd i say...

it should be behind the passenger side kick panel..somewhere.

if its not there, perhaps it was bypassed (they DO occasionally fail).

but it doesnt sounds like the inertia switch is your problem. the switches do not reset themselves, so if the switch was tripped, your truck would not start until you located and reset the switch.

It can also be up below the heater box above the passenger feetwell

that's the thing, i had somebody who has done this before show me where it is. and it is not there.

i have the same ranger and i would just disconnect the negative and positive on the battery let it sit 30 seconds then it would start, it usually happened to me when i sped offroad on bumpy terrain.
disconnecting the battery might be bad for all i know so if someone could verify that you can do that as well.

yea if somebody can confirm this it would be really helpful

your computer stores information about sensor input from the last 80 drive cycles. it uses this information to form a baseline reading for a given sensor under a given set of driving conditions. it uses this baseline to identify when a sensor is way out of its normal range (meaning something is wrong). it also uses these baselines as a multiplier to compensate for a sensor or engine that is getting tired and not quite up to factory specs. unhooking the battery clears the PCMs keep-alive memory and these baselines...meaning your PCM will have a harder time identifying an engine that is not running properly or a failed sensor...it also means that worn sensors or engine components will not be compensated for...costing you fuel efficiency and power (though the effect may be small and unnoticeable).

of coarse your PCM will eventually figure it all out again, but it takes time. if your after maximum fuel economy and power (and who isnt), you should avoid unhooking the battery if you dont have to.
