Question about Jeep Cars & Trucks
No shutoff switch they will have an electric relay.
Posted on Dec 15, 2016
There is no inertial switch like fords
but all cars by law the PCM is programmed to cut fuel for many reasons. i can list them there are up to 8,.
the ASD relay controls this. and more, read...
if you had scanned the PCM you'd would have found out why already. fuses not blown.
why not post the symptoms first and not a hunt>?
my guess is engine stalls or will not start but cranks ok.
and the CEL glows key on , in the cluster,
the fuel cuts, are USA laws, most of these are
to stop Crash and burn as seen on TV.
Ill add 2 more
the PCM is programmed to cut fuel at WOT cranked
this is a feature, called UNFLOOD Mode, as covered
in the operators guide.
that means if you had a bad TPS , that was stuck
at 100% throttle (4-5vdc) the ECU cuts fuel.
(be that shorted wires, or bad TPS)
all gas engine PCM/ECU cut fuel if it senses dead spark or dead tachometer. (DTC for sure)
all gas engines EFI works like that.
Jeep adds to the mix.
(immoblizer is one)
VTSS,VTA,SKIM, immo (most GC have it)
is your IMMO lamp glowing? or flashing.???
this lamp is first.
