Question about Isuzu Cars & Trucks
Why not post the symptoms first, then ask questions.
its not a ford, is my first guess.
my guess. your engine will not start.?????????
the 4ZE1 engines.
"The 2.6L 4ZE1 SOHC eight valve engine features 120 hp (89 kW) and was available as an option to replace the 4ZD1 on four-wheel-drive models."
i dont think there is a reset. like seen on FORDS. its no ford.
if the engine wont start (right>?)
but cranks, great and fast....
and spark is good on all cylinders, not just one and is timed right.
then it's a fuel problem (guessing engine good i am, foolish i am...)
so does test fuel run engine for 3 seconds, ???? (need a video of it)
yes, ? then it's a fueling problem.
so next is fuel pressure cranking, you must crank it.
(on mine , i cant hear my fuel pump spin cranking, too noisy starter)
but if i stick hose in the gas filler next and mech 2 cranks, i can hear it spin, other cars, its very noisy, like my new chev, pu truck.
if not spec pressure check the voltage to pump cranking
12vdc, cranking, good, 0v bad.., 6 v bad, 8v bad.
see>? the voltage matters,! @pump pins.......
now if no voltage to pump ,then we scan the PCM. (flash codes )
if the PCM (ECU) seens spark missing , even if good or tacho signals bad, or cmp bad, or ckp bad or , TPS stuck at 4v
the ECU CUTS FUEL and some even cut pump.
this is by law, to stop crash and burn as seen on TV, (omg)
i dont like easter egg hunts, why do that to pro help, and free!
the car has an ECU and all have flash codes.
you insert the diagnostic jumper and crank for 5 seconds, and the ECU tells you why it cut fuel. (4/5 cases)
it will not , if spark plugs are shorted etc.
it will not if the TPS is stuck at 4v output. (unflood feature forever)
but will for 4 other failures.
ckp (if fitted)
tacho pin dead.
all efi cars 1988 to now, do that. The CEL lamp blinks. a CODE<
and cost nothing to look, on all cars up to 1995. when the blink codes go dead in USA> forever. (OBD2 tech) EPA laws.

if the grille screws are accessable remove the grille which should give you access to the underside of the lock, you may need a screwdriver to push the lever aside to release the hood
Hope this helps

SOURCE: Where is the obd port
Here is a photo of the obd connector on a 1993 Isuzu Trooper.
The connector is on the transmission hump about 6 inches from the accelerator pedal. It is inside a black hood. Right next to the white OBD connector is an identical green connector that I have not tested.
The OBD port is a white 3 hole plug. Right next to it in the photo is a green 3 hole plug that I believe is for automatic transmission diagnostics. The plug is different from other plugs under the dash as it will not accept a .25" tab connector.
The picture shows a 20 ohm resistor being used to short pin 1 and 3 of the white plug. The resistor is to prevent a melted wire in case the plug shorted is the wrong plug.
To read the error codes from the engine computer, the mechanic is supposed to short pin 1 and pin 3 of the OBD port plug. Then the mechanic turns on the ignition switch and counts flashes of the "check engine" light to determine the error values being reported.

As you have not specified engine size, i'll give you both capacities.
Oil Capacity for 1995 Rodeo, is:
2.6L Engine - 5.8 qts (with oil filter)
3.2L Engine - 6.2 qts (with oil filter)
