My truck ran fine yesterday. It has a fresh tune up, good spark, fuel pressure at 36psi with vacuum hose attatched, and proper timing. I had my truck in storage for 2 years with gas stabilizer and decided to empty the tank and add fresh gas. Now it won't start.
The truck will fire intermittently while trying to start and produces black smoke. The engine is flooding at startup and the spark plugs were a wet black color. I cleaned the spark plugs with acetone and it still runs the same. I noticed that the throttle position sensor was disconnected so I reconnected it and pulled the ecm fuses to clear the code. There was no change. Unfortunately, I cannot get the truck running long enough to set any trouble codes if there is one. Please give me and idea what to check next.
