2001 Chevrolet Astro Q&A

2001 Chevrolet Astro Question: I have a 2001 astro minivan 4.3 liter engine

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? -
Answer 1
Best suspect is the intank fuel pump module. Needs a new fuel filter also. Mechanic will test pressure to confirm! -
Answer 2
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? -
