Trouble starting Rodeo after driving for a bit.

I have a 1992 Rodeo v6 . The rodeo starts most of the time but when I have been out for a while sometimes it will not fire when starting the engine. If I leave it and come back later the Rodeo will start up and run. When it won't start it floods out and I can smell the gas so I assume filters and fuel pump are ok. It will fire sometimes and immdiately shuts down like it may be the carburator. But in the end it will start and run just fine. I just don't have a clue when it won't start on me again. It is intermittant.

I have a 1991 Rodeo v6. I have experienced a similiar problem, and although I think I know more about the problem...I don't know how to fix it either....help !!

My problem isn't a result of running a while, but rather when it is started, if for whatever reason....the starter is disengaged prematurely (such as releasing the key-ignition too soon, or releasing the clutch too soon). Point being, if you don't get it started on the first try, it will continue to crank, but floods out badly...as you mention, you can smell gas ! So what's happening is the computer keeps dumping fuel thru the injectors and it floods out....the more you crank, the more it floods. The only way that I could eventually start it was too let it sit for several hours....until the extra fuel has disappated.

After I finally understood this, the next time it stalled, I removed the air-cleaner cover and disconneded the wiring connectors from the injectors (2). Crank it again, and it will start immediately, and run for a few seconds until it dies from lack of fuel. Then you can plug the injector connectors back in, and it will usually start immediately. Try this, and I'll bet that it will start immediately.

I explained this to my local mechanic (no Isuzu shop nearby), and he changed out the computer....$300 bill. Worked for a few weeks, then started again. Another mechanic hooked it to his diagnostic computer and said that the temp sensor was bad. $200 and we changed out the temp sensor....but it still stalls on start....the last time stranding my wife in town !! She's fed up and is ready to dump the vehicle. I love it, but need to get it figured out, or it will turn into a Ford pick-up.

Anyone have any ideas ???

I spoke with someone about my problem and he suggested that I should check the electronics starting with the I think its called the ignition coil next to the distributor. The thinking is that over time they can develope hairline cracks and when you hit a specific operating temp that when you try and restart the engine it is unable to provide the spark necessary to ignite the engine therefore flooding out the carburator. I have not yet replaced the part but will do so shortly and probably replace the plug wires as well.

You may want to throw some dry gas in your tank and see if that fixes it. If you get water in your tank, it will start to collect on the mesh "sock" filter on the intake for your fuel pump as it cannot get through. Eventually, it will slow the fuel flow to the point of stalling out your truck. After the truck sits for awhile, the water will drop off the sock and allow starting again, only to be repeated. It's an easy thing to try.
Not too sure about your problem, dnoel. Sorry!
Good Luck, guys!

After replacing the plug wires new distributor cap and rotor, New coil, and checked chassis ground. Still had the same problem but it finally was getting worse. Starting to stall and cut out while driving. I did replace the ignition module which is housed in the distributor a year ago when it died all together. I decided to replace that module again and she runs great. No stalling no staring problems when hot. It was my ignition module that was causing my problems. She starts all the time now.
