Question about 2004 Dodge Ram 1500
5.7l engine that is hard to start. have to flood the engine to get it to start then it burns a lot of gas when started. It has random misfires. Relplaced the fuel prusure relay that was pushing 80PSI and think I may have a leak somewhere in the fuel system. May be in the return line of fuel pump. Have replaced all sensors but the throtle body/throtle possitioning unit and fuel injectors and fuel pump. Don't see or smell any other issues with fuel line.

You should definitely replace the fuel filter though this probably won't fix your hesitation. It wouldn't hurt to replace the spark plugs this is usually the culprit on these engine. I have the same engine in a '99 caravan and found the for some reason the spark plugs on cylinder 3 and 4 loosen up after one year and cause a misfire between 45 and 50 mph under load (when mildly accelerating).

turn the key to the on position a see if you can here a buzzing sound around the fuel tank,if you don't hear a sound then. (be very careful while doing this) with the key off take a fuel line coming from the tank loose,make sure its pointed away from you and turn the key to the on position,see if any gas comes out,if not then your fuel pump is probably bad.

The "wait to start" light is your glow plugs. You must have a loose connection to them or something not connecting. They come on almost everytime you start them, hot or cold.
