    Where are you checking for spark... at the coil pack or at the ends of the wires. ?

If you have no spark on the coil pack for these cylinders, try scanning the car to see if you get codes for a camshaft positioning sensor or crankshaft positioning sensor.

My Isuzu 220le has no spark on cylinder 2&3 but continuous spark on 1&4. Single coil pack system and it back fires each time o crank. Changed HV cables and plugs but still not running


see if u are getting spark from the coil itself (fm 2& 3) It may be the coilpack itself, cam or crank sensor. Start w the coil.

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 would say its the coil. A crank or cam sensor could cause one cylinder to miss, or go completely dead, but I doubt it would affect two cylinders. And you would get a code for either sensor.

If there is spark to cylinders 2 & 3 than it is not the cranks sensor. Cylinder 1 & 4 are on the same coil and cylinders 2 & 3 are on the other coil. Replacing lithe coil pack will likely solve you lack of spark on cylinders 1 & 4.

I RECENTLY THINK I HAD PUT SOME BAD GAS IN MY 2001 LINCOLN LS AND IT STARTED TO MISFIRE SO I DROVE ALL THE GAS OUT REFILLED IT WITH SUPREME AND GAS TREATMENT AND STILL WAS HAVING THE PROBLEM WHEN I REACHED...


Without seeing the car would say to do these things. Check for vacuum leaks on hoses, see that the mass air sensors is hooked up properly. Look for exhaust leaks, there could be air **** in causing the oxygen sensor be thrown off. Look at the oxygen sensors to make sure they're not damaged. Next check the ignition system. If the mis is constant disconnect one sparkplug at a time until you find which cylinder is missing. Switch coil packs to another cylinder to verify this. If the ignition seems OK you might have a bad sensor. Mass air or throttle position sensor. Good luck.

I have a 2002 TrailBlazer with the straight 6,diognostic check said #3 cylinder was dead or misfiring, also map sensor showed up. #3 cylinder was misfiring, so to test the coil pack I swapped #3 coil pack...


did you replace only one spark plug? that can cause issues because of differences in resistances between cylinders. also, did the map code stay off after replacing
?
