SOURCE: timing mark's on isuzu trooper 3.0 td

The cam pulley notch goes in line with the mark on the front cam bearing cap and the crankshaft pulley goes at 12 o'clock - its got a tiny mark on the back lip that lines up with the mark on the cover .

Did you take the cams off in one lump or split them ? if you did come back on here for how to time them up .

SOURCE: My 1990 isuzu trooper was driven to town when it

replacing the head gasket solved one problem.
But, you have a leakage problem with oil and/or antifreeze now.
The head gasket could be failing again, or you have a cracked block or cylinder head.

Take it back to where it was worked on and say that you want it fixed, please.

good luck on this.

Drivers side has spark and fuel when using starter. But no fuel / spark when running on the passenger side cylinders? None of the drivers side cylinders fire!


are yous saying engine runs on 3 cylinders, (sure dead slow)?
great facts, so few post have actual facts or tests
but what engine, it's engine issues, which one?
must be v6, (left right bank)
but is it single or twin cam 24valves?
check all fuses first. (always)

lets see... one side has no spark, so did you scan he PCM while cranking for P03xx codes DTC errors. it will show them if you crank for 5 full seconds, and release the key , 90% of time.
and is a KEY fact in diagnosis, no need to fix cars like 1995 and older here. we use scan tools and win,.

left side has spark and fuel but is dead, so its flooding on that side.
right bank has no spark and no fuel.
you meant both sides dont fire. and engine does not run at all.
so what is wrong.
well I check spark first. is the timing good? if not the cam belt slipped. as all do , ignored.
5 min check and bam , OMG timings way off....
or check compression first. i do on all old cars.
for 2 reasons.
1:if compression is way off, the cam belt slipped.
2: if uneven , (done right) you go , gee, is this old car worth a rebuild? 13 years old, IMO , it is. but isuzu parts. hard to get?

do compression on #1 clylinder (or 3) first. if way off. bingo.
5 min work done WOT, wide open throttle.
bingo

line up
3.2 L 6VD1 SOHC V6
3.2 L 6VD1W DOHC V6 (w = 24v)
3.5 L 6VE1 DOHC V6

which one????????

knowing engine, tells the mech, what spark system is there and which of 2 fuel systems used.
see?
does engine have 1 coil pack with 6 lugs, or 6 cop coil packs.
see?

if compression is ok.
and one bank is dry.
that means the injectors are dead on one side.
and that means the PCM is seeing bad CMP sensor data.
some CMP can do that. but no engine stated.
SOme CMP sends camp pulses for all cylinders can can fail on one bank.
but if the cam belt slipped, some PCM go nuts with crazy CMP pulses.
let me explain if you were a PCM and the cam and crank signals.
are in contradiction, do you inject or not? (pretend that)
some do, some dont other guess wrong, or go goofy.

the spark and injections are all timed.
that is why I always check spark timing First.
a 5min job.
the new cars have no spark timing adjustments
and many think that is excuse to throw the tool away
nothing is so far from the truth...
learn this. and win...

I have a Mitsubishi gallant cylinder number 1 not firing but spark plug is firing engine misfire,engine check comes on for it to start and it has a hard start help.


If you have spark, but no fire, then check injector for proper activation. If good, check compression. If injector good, and compression bad, possible head gasket, valve, piston, etc.

Firing order 1994 iszuzu trooper 3,2 sohc


its a V6
Order: 1-2-3-4-5-6 Distributorless Ignition System
outside usa , ive not a clue.
and i bet you are.

3,2, tells me (not USA) comma for decimals.was the clue.

EFI systems vary world wide)
the firing order on ours is per above, im not sure how many 3.2v6 are made world wide, with different crank /cams.
seems there are 3 if you read the wiki......

there is a gm v6 LG6 is 3.1L and isuzu v6 (x2) 3.2L
the real Isuzu is called 6VD1 engine
later years GM 4.3L
my guess is 6VD1 or W

and 6VD1W. twin cam. introduced in 1996 on troopers.

76 degree V 6's
per the wiki
The feature either a belt-driven SOHC or DOHC valvetrain. Later versions feature direct ignition as well as gasoline direct injection. These engines are notable for their early adoption of gasoline direct injection technology and also for their uncommon 75° cylinder head bank angle.


before i work on and engine i learn what is there first.
as you can see wide variances there are.
post country first. then if single or twin cams.

but the firing order is dictated by cam and crank geometries.

2000 Isuzu rodeo , no compression, drivers side


Cam timing not correct on that bank. Veryify cam timing. Not sure if the engine is a "zero clearance" engine but, if so, the cam timing error may have bent some valves! Oh nooooo!

1997 Jeep Cheerokee does not have fire to spark plugs


Have you checked the injector harness for a proper injector pulse? The ECM pulses the ground circuit to fire these and if there is a short in that ground wire the injector will stay open all of the time, effectively flooding that cylinder.


If it has spark, fuel, and even compression, it has to have integrity with the valve train. If you can pull the valve cover off, turn the engine over by hand to make sure that the vales appear to fully open. You can compare them to the other cylinders. It could have a flat lobe on the cam. A compression test wouldn't necessarily pick that up because the cylinder would still compress whatever air is still in it.


Hope this helps.

Isuzu trooper starts briefly then dies


check your fuel delivery from the pump to the "dry" pulsing injectors leave the crank sensor alone! open the intake and, spray either (engine start) into the engine then attempt to start; it should start and, run until the either is used up then die. most likely your fuel filters are clogged

2001 jeep Grand Cherokee fuel injectors


check the injectors on that bank for pulses.. a regular 12v text light will do it should flash when cranking... its very possible that the crank sensor or camshaft sensor on the replacement engine is bad and giving you all the problems you have now.. are you using the original injectors? if you have injector pulses then check the coil for pulses the same way.. btw make sure you have 12v to them even before cranking engine could be a bad asd relay..wet plugs on one bank would also indicate a possible leaking injector and basicly draing the fuel starving the oposite bank for fuel.. to verify that the rail must be lifted by removing all 4 bolts make sure the clips hold the injectors firmly and turn the key to run but dont crank it then look for fuel leakin from bottom of injector(s) any drips is a bad injector..
