I would start with getting the right firing order you can look up the spec online at autzone on there site they always have diagrams than start by checking and making sure that your getting fuel either a clogged fuel filter or a bad fuel pump that is starting to go bad. Make sure you only have 1 fuel pump some cars have 2 if you have to chances are the one inside the gas tank is the one that 99% of time goes bad but check both for fuel coming out of them to be sure. To me it sounds like your ignition componenets need to be checked and make sure your confident on your firing order than start diagnosing .

I have a 1997 Isuzu Rodeo 2.6L cylinders 2 & 3 won't fire after vehicle starts but will fire if I unhook cylinder 1 or 4 what will cause this


USA car? must I GUESS?
so you have 2 coil packs. ????
called wasted park
seems you typed the displacement wrong, !!! 2.2L is 4 banger...
1 and 4 fire as a pair
2 and 3 , fire as a pair , in series

so if the spark wires open , you loose a pair,
say #1 opens, you loose #4 with it.
they are wired in series.
if one spark wire grounds out , you lose only THAT spark plug.
but why would you get the odd pack to pack cross talk.
(assumes you have the HV wired right. correct?)
the packs cant be wired up willly-nillly.
this is the 2.2L coil pack.
and IS wasted SPARK system. for sure.
and can not be mixed up
the PCM is hard coded for 1,3,4,2 firing order.
and must be wired right. did you meddle here?
if you unplug the 2 one right , this must not make the 2 on left work.
pulling 1 wire, only kills the adjacent wire. normal.
see the pairs there, at the bottom see those hiddencoil packs mail coils molded to case?
if you are wired right and you have cross talk from 1/4 to 2/3 bank
the pack is bad.

25857019-xm4r4cd100gbehm3txueal2s-4-0.jpg by cross talk i mean, 1;3 effect 1/4 or the reverse.

Multiple misfire on my 03 rodeo izusu. spark plugs and wires, coil pack,coolant sensor changed. Not sure what else there is I can do.Any one having the same issue ? Help


In brief, you need spark at the right time, fuel, and compression to have power.
You would need to know if you have all three on all cylinders.
This would include fuel injectors and engine valves.

If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.

I know for your car, the ps701 is useful.

If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.

A misfire alarm typically means the coil pack mounted above the sparkplug indicated in the misfire had gone defective.

To test it, swap the coil pack with another cylinder, and see if the misfire goes from #2 to the cylinder you put it on.

If the misfire continues to be on #2, then consider changing the sparkplugs.

I hope this helps.

If the coolant temperature sensor is sending false low temperature readings to the computer, it could cause the computer to send too much fuel through the injectors causing rough running, spark plug fouling, and poor gas mileage. Replace the sensor, clean or replace the plugs, and see if it runs better.
