Were is 1999 chevy blazer fuel preasure regulator located on motor

SOURCE: 1999 Chevy Blazer Starter

the starter is located on the passenger side lower motor. it has two bolts in it that hold it in place. it actually goes through a hole/slot in the transmission to the flex plate.

1st. disconnect the negative cable on the battery.
2nd. raise the vehicle safely and place a jack stand under the vehicle out of your way but near where you will be working(for safety).
3rd. remove the two bolts that hold the starter in place.
4th. remove the wires from the back of the starter.
5th. install in reverse order of above.

note: there may be little plates between the starter and the mounting points called shims. if there are then make sure you put them back.

SOURCE: 1999 chevy blazer fuel problem

probably not fuel filter . probably going to have to remove the upper intake and replace the fuel injector spider(fuel inj assebly) if it is droping fuel pressure it is leaking into the upper manifold

THE FUEL PUMP IS BAD.

if your losing fuel pressure after the pump runs the drain back valve in the pump has failed.

and i doubt that you are seeing enough fuel pressure to run a vortec engine.

low fuel pressure equals a non running vortec

SOURCE: fuel pressure regulator location

the fuel pressure regulator is on the fuel injector rail. it is where the fuel line for input connects to

Two places to look...if you have separate injectors for each cylinder then regulator should be at the front end of the fuel rail. If you have throttle body injection it is on the throttle body itself.
