2002 Chevy Blazer will crank but not start

Unread post by Brent » Thu Jan 21, 2010 11:50 am

Everything was fine until i started working on the ball joints. I know it makes no sense but after I was done The engine would crank but not start. It would back fire and diesel. after killing the battery, I charged it up, put it in nuetral and finally got it to start. It ran rough for awhile and then everything was fine. Until today when I when out to go to work and it just cranks. I can hear the fuel pump come on and stop. Any Ideas?
PS it has a new fuel pump (2 years old), and has had a tune up

Well, you really need to check fuel pressure. Just because the pump runs, does not mean it has enough pressure.
I suppose doing the ball joints and having the truck tilted to one side (unless was up on a lift) that some dirt may have gotten sucked up in the pump or in the filter.
