Took off fuel lines from midde to back and now trying to figure out how to hook them back up 1998 Chevy Blazer 4.3 4 dr

You have to reove the upper plenum. that is the part on top of the intake that looks like a dome on top of the lower intake.There is 8 10mm bolts around the outside of the dome part. the disconnect the fuel lines at back of lower intake and remove the cpi unit.

Sounds like it is skipping? If yes, you may have lost a cylinder, due to no spark, or a bad fuel injector.

In the glove box behind a plastic panel. There are 3 relays in there. The fuel pump is the one closest to the drivers side.

Your fuel pump is located inside your fuel tank. You need to drain and remove the fuel tank to replace it.

Hook up a fuel pressure guage. Now with the key on and engine off does the fuel pressure come up fast and hold steady at a fixed value?

some applications required a security by-pass piece of equipment a small black box , make sure yours did not have one ,if so remove . as well as a hood switch make sure the break in line for the hood switch is made back up after you removed the piece of equipment .
