that post makes little sense.
#5 and 6 means what? add 1 noun please.
spark is good to
all 6 cylinders.
no fuel out of all injectors.
THe ECU spark the spark plugs
and if the ECU sees gross spark errors it cuts fuel ,hard pure logic in the ECU does that and by law
ever to the 1994 ECU DTC diagnosic jumper flash code tests
in the service manual>
this is a gasoline engine (petrol Otto cycle rules) and as such
engine must be good first. 150psi compression x6 is good
and next is spark good on all 6 , not just 1,
how many spark coils are there, 1994. (spark tech changes fast then)
the 4.0 has 6 lug HV terminal coil pack and must not be wired up wrong because this coil pack as 3 coils inside,
called wasted spark
and if wired wrong 2 or 4 or more spark plugs fail for firing order.
and time.
they still spark but at the wrong time.
not the distributor version but is DIS system.I am taking, vin X
Vin -8th = X 4.0, no distrib.
if engine was good, and spark was good even a fully dry fuel TANK
test fuel works now, (spray instant starter fluid) for 3 seconds. each try.
i bet yours fails that test. or sounds horrible misfiring badly.
crank senors dead
cam sensor dead. (cam shaft synchronizer, seen where old disributor was older year) either sensor dead,
FUEL IS CUT by LAW.
do not mix up the wires or doomed misfire grossly.
