My truck has a fresh tune up, good spark, proper timing, fuel pressure at 36psi, with the vacuum hose applied, and ran good yesterday. The only thing I changed in these two days was the gas. The truck was in storage with gas stabilizer for two years. I emptied the tank and added new gas.
The engine is being flooded with gas at start up. The spark plugs are a wet black color and the exhaust is black. I noticed the throttle position sensor was disconnected and reconnected it. Afterwards, I cleared the ECM of codes by removing the fuses and tried to start it. I can't get it running long enough to check for more codes. Please give me some ideas of what to look for. I don't know how to disengage electronic choke if exists.
