The backfiring is a sign that the distributor is indexed improperly - or the plug wires are mixed up..

First, you need to set the engine at Top Dead Center on compression stroke.

Easiest way is to take the distributor back out first - then pull number one spark plug, put your finger over the hole and bump the starter with a remote switch or someone at the key.

When air starts to push out, then look on the pulley for the TDC mark coming up on the pointer - line that up.

Then locate the 2 dots on the distributor shaft, one on the shaft by the gear, and one on the gear - line those up. OR - find number one post on the distributor cap, and make sure the rotor is just getting to the number one post when the distributor is seated in the hole. If not, just pull the distributor up enough to catch the next tooth until it is sitting properly.

Let me know what happens please. The more details the better. Good Luck

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.

Have just put new head gasket in our 4ze1 after blowing a heater hose. motor now hard to start and wont idle but runs well out on the open road. does everything right on the open road - pulls up hills etc...

plug gap 25 th ,too wider gap and it will be hard starting from cold ,as for idle then this could be a vacumn hose perished or not reconnected when head gasket changed ,or a vacumn pipe has been damaged whilst changing the head gasket follow then all back even the best of us inadvertantly damage things or drop a bolt somewhere that always rattles afterwards

1991 rodeo starts chugging after engine has warmed up and driven 20 to 30 minutes - usually recovers but sometimes engine completely dies and can usually be restarted

Mine had a similar issue. You might try changing the ignition control module in the distributor. I changed out several parts because every place that checked it said it was good. But I decided to change it and it ran fine afterwards. It should only cost around $30 for a basic unit, unless you have a shop install it. But it does sound like its something that's on the engine and has trouble operating when it gets hot.

Isuzu Rodeo w/3.1L engine

Front Passenger side on cap is 1 - if you look on the inside of your cap there SHOULD be a pin marked with a 1, and the plugs go CLOCKWISE not counter. Just had the same problem myself with my 91 Rodeo. Cylinders are as follows Passenger side (front to back) 1 - 3 - 5, Driver side (front to back) 2 - 4 - 6. I called the Isuzu dealer and they told me it was counter clockwise, but when I hooked it up that way it backfired through the Carb.
