Well gang I have solved my problem and I will share it. Since most of my original thread is gone here is my story in a nutshell. My van is a 1993 only used on weekends an vacations. It had 60,000miles and I had never had a problem with it. One day we got in and it would not start up. The following week was a nightmare of trial and error. I went from replacing every ignition part I could to contemplating replacing timing chain and sprocket. What was happening as I said before after I put new plugs, rotor,and cap on the engine and it started. Well that was short lived after about a minute it would start to chug and blow smoke then die. It would not start again. The next day I tried a brand new ignition module and it started again only for a minute or two bellowing smoke and smells of gas. I then pulled a couple of plugs and noticed they were wet. The whole time I am checking things I had been getting spark but now the plugs were fouled and would not spark. I had been getting all kinds of advise and looked into each one. It was getting vary frustrating but I did appreciated all the advise I had been getting. Pretty much everybody has said the same thing "If you have gas-fire-air your engine should run." I guess that used to be true till the inception of the computer. This computer has thrown a monkey wrench into logical thinking. Getting back to my problem solving I bought new plug wires and plugs to replace the fouled plugs and old wires. I tried that and it started once again and seemed to run a little longer but I could tell this was not the answer either and I shut it off the engine and came back here to this group looking for answers again. I was reading a thread were a guy was having trouble with his Silverado running to rich and stalling alot. Somebody had mention if he checked his coolant temp sensor. A recommendation was to disconnect the sensor and try it. Well I am game what the heck I have tried everything else so I disconnected the coolant temp sensor and started the
350 up. WOW! started up like nothing ever happened my mouth dropped and I think my heart skipped a beat!!! Geezzz a $8.50 part cause so much grief. Replaced the part and runs like a champ.Ah I can sleep again.... I hope this will help somebody that might have the same problem. I guess my coolant sensor was shorted so badly that it was dumping so much fuel that it could not start up correctly. Thanks to everybody who helped me I hope this helps somebody.Mike
