I have a 97 Chevy blazer replaced fuel pump ran good for 2 months then I had to use starting fluid to start it then while driving I lost power and started to have a misfire really bad made it home checked fuel pressure and was at 35 so I replaced fuel pump again and I tried to start it and backfired real bad and white smoke through the air filter wouldn't stay running so I changed the fuel pressure regulator and then it started but has a horrible misfire and will die if I press the gas I did a compression test on all cylinders and average from 120 to 100psi hope someone can help me out with this problem

Anytime a fuel pump is replaced the Fuel Filters need changed, 1 sock filter in the gas tank and 1 "in-line" filter under the hood.
Also, using starting fluid for an extended period of time isn't recommended as a "work around" to starting problems. You may need to have the throttle body looked at and a complete tune-up done as a result.
