95 Blazer 4WD 2D Fuel Mystery Challange

07-09-2007, 01:15 AM
I own a 95 Blazer 4WD 2D with 120,000 miles, Replaced Fuel Pump, CPI unit, Fuel Sending Unit....... Fuel pump ground ok, engine has spark, But now for the strangest part .... runs extremly smooth when jacked up high on the pasenger side about 2 ft off ground, but when on ground runs extremly rough while idoling followed by cutting out and shutting off, fuel pressure good. Having a Friend come over to take a look tomarow. I would highly appreciate any answers or even questions. checked fuses to. The only thing we havnt done is tried is Delco fuel pump. So Maybe a pinched wire or fuel tank level who knows theres gas in there about 60% full so good luck on this one dudes and its used to so later

Sounds like the fuel pump or internal fuel pump/module plumbing is real marginal...raising the fuel level to the fuel pump when you raise the passenger side must cure it temporarily. You could also try adding several gallons of fuel to change the level.
