Question about 1991 Isuzu Rodeo

2 Answers

Hi. Thanks for having this available! Our 1991 Isuzu Rodeo V6 suddenly wont start? It cranks great, and obviously has fuel by sight and smell in the throttle body. Even quick-start couldn't get a puff out of it? I figure it's ignition but where do I start? What is the mostly likely culprit in your experience? I REALLY appreciate any help because it's an hours drive each time I try a new part plus the wait just to get it. Thanks !!!!! ;-)

    Hi again. The engine cranks over great so I know the battery and switch are ok. It's deffinetly ignition from what I can see. I'm just wondering what is the most likely culprit on this model vehicle for sudden, complete loss of ignition?

    As I said, the engine cranks great so it's not starter, battery, or ignition switch. It also gets lots of fuel. Just wondering what may be the most likely cause of no ignition on these vehicles?

First thing to check is when you try to start do yo hear a click sound from under the dash. If you hear it check the baterry terminals . Clean it and try starting them again.

If still it didnt start it would be likely a bad ignition swtich.This the most common thing which happens.

First switch on the interior lights and try starting the car so that see whether the light is getting dim. If it is getting dim then surely the problem is electrically related.With either the ignition or battery.

Make sure that you get 12.6 volts supply from the battery terminals.

97 Isuzu rodeo v6 motor won't start after disconnecting pcm before disconnecting the battery. Replaced pcm properly still won't start.


auto or stick shift transmission?
correlation is not always causation.!!!
example: if I open the glove box, and the engine stalls, It probably is not the glove box lamp doing that.

The 97 cars have very few learn modes.
in fact, none kill engines dead, ever.

the trouble with your post is it says nothing useful. sorry.
1: cranks robustly but will not start?
2: will not crank, or just clicks, or the starter motor is silent.?
the starter can also chatter, or free run, spin fast but engine not.
if it wont crank ,
jump start it, if it will not cranks still , crank in NEUTRAL.
PRNDL move lever to N per the steps in the operators guide.
3: cranks ok, there are 50 reasons for that.
if your car reads statistics, the spark plugs are bad, ignored.
do say this time what the engine did. exactly , you did not.

4: cranks ok , do so with wide open throttle to clear floods
this is secret mode in the op. guide that cuts off the fuel injectors.
V6, 3.1., 3.2 , 3.5Liter?

My Isuzu rodeo will not start,,tries to turn over , but wont..gets fire, get gas..just will not start.


If the spark to all plugs is healthy and that spark coincides with the introduction of the fuel then it should start. Is it catching at all when being turned over
Have you had the timing checked?
Is the fuel pressure good?
I would....personally speaking, perform a compression check and, if that proved okay, I would have an OBD scan to check for error s then go from there

Why is my 2001 Isuzu Rodeo V6 so hard to start?


your problem may not be electrical at all... have you done fuel
pressure test ? simple things like a blocked fuel filter or pick up, will be trouble starting. also check fuel pressure regulator.

I have a 1992 isuzu rodeo it wont start the engine is turning over but it still wont crank?


To clarify, if it turns over it cranks.
If you know it is not getting spark to the plugs, you will need to have someone check the rest of the ignition system including cap and rotor, module, and pickup coil in the distributor. (V6)
The first thing a mechanic would do is make sure the coil has voltage.
