I have a 2001 astro minivan 4.3 liter engine on 2001 Chevrolet Astro

I have a 2001 astro minivan 4.3 liter engine and it will only start if I put starting fluid or mass air sensor cleaner into the intake, but after it starts it will run although its rough and if I give it a lot of fuel it bogs down. What could possibly be the problem?

Best suspect is the intank fuel pump module. Needs a new fuel filter also. Mechanic will test pressure to confirm!

could be a hand full of things, ex: IAC motor, MAP sensor, Coolant temp sensor, also check coolant level, as is the same engine in chevy blazer had seen a few that would not start right with low coolant..any engine light or codes?
