So, I bought this truck, and it had a few things wrong with it that I knew I could fix. Needed a new steering pump, needed new tires, a good fuel cleaning, and had an idling issue. Bought it for only $750 and thought nothing of the idling issue. In the morning, it would start and then want to die. I would be able to pump the gas until the check engine light would come on and the truck would not die. It would drive normally. I started replacing things including the Manifold Air Pressure Sensor, Throttle Position Sensor, and the Vacuum lines. Cleaned the Throttle Body and replaced the gasket as well. After doing this, I tried to drive the truck, and now, the check engine light won’t come on. Before replacing the Fuel Pressure Regulator, I wanted to take a look at the computer, and I think I found some issues.
My questions are: Can this be fixed? Is it worth being fixed? Should I just switch it to carbureted?
