My 86 ranger is fuel injected with a manual tranny. I have stalled it a couple of times when it was cold, and it did try to flood on me. I cranked it over a couple of times and when it did not hit a lick, I went ahead and held the pedal to the floor and cranked it, and this clears it out every time. When the rpms are below a certain number and the throttle position sensor shows wide open, it turns the injectors off. There must be some scenarios where it can flood if they put this feature in the programming.

Thank you Franklin. I have been doing a lot of searching the web for answers and I think I have discovered what is causing my problem. I believe it is the timing chain. I read an article about a guy who had some of the same problems , wet plugs, not starting, not running, etc. and he had the same year and engine as I do. His problem ended up being the chain. He mentioned that the motor would change tone and speed as you would crank it and mine does too. What are your thoughts on this?

The plugs were not dripping wet but they were wet and had a strong gas smell. I did not know that plugs would not fire if they were wet. I thought they would fire and dry themselves. I will get new plugs and put them in. What would cause them to get too wet in the first place and what will prevent the new ones from doing the same thing? Thank you for the suggestions.
I don't know if your spark is weak or intermittent, both will make plugs get soaked. In order to verify both spark at the plug and know if plugs are even firing... pull out a plug and reconnect it to wire. Hold it against block and crank. Pull fuel pump relay while doing this to also prevent further fouling.

If you want to see how loose it is, you can pull the dist cap off, turn the engine by hand one direction till the rotor turns, then stop and turn the engine by hand the other direction. If you can turn the engine a lot before the rotor starts turning the other direction, there is a lot of slop in the chain and sprockets.

Thank you Cuba and Franklin for the help and suggestions. I finally had the time to work on my truck this past weekend. The teeth on the camshaft gear were half gone and after getting the cover off the chain just fell off. I have it back together and it runs like a new motor.
Thanks again. Your help is much appreciated.
