new guy here in south central PA
Hello all. I used to have a 98 s-10 pickup that I loved but I got rid of it awhile ago bit now I have a 97 blazer and thought that the power would be similar but I was wrong. I know the blazer I got has some fuel issues as I did a leak down test and I came up with 55psi but as soon as I turn the key off it drops to 35 within the first minute. I already replaced the pump and regulator but not the injectors and I'm now not sure if its the pump allowing it to leak back or crappy injectors that are leaking I'm strapped for cash so I don't wanna go throwing parts at it is there any way I can test it from this point ? Thanks for any help I might get I appreciate it
Welcome to the forum.
We usually ask that you post your questions in the appropriate sections, as the new member area is just for introductions.
That being said, there is an adapter for fuel pressure testers that allow you to connect it to the fuel filter to isolate the pump so you can test the check valve alone. If it drops using that, it's the pump (or lines from the pump to the filter), if it does not, you're looking at the injectors, FPR, or nut kit.
