95 blazer fuel issues

It wasnt the regulator it was the pump.Just cause the pump runs doesn't mean it is pumping what it should.I didnt have pressure at the schrader valve which is before the regulator.

You got lucky seeing in most cases it is the regulator leaking.

I would still inspect it by removing the top round IMTV valve and takign a flashlight and shining it in and looking for washing.

Indeed, in my case it was a one-two punch combo. I had rough idling, taking mutiple turns of the key to start the truck. (Always started on the third try) First it was a leaking regulator, in which I replaced the entire spider kit and nut kit. That worked for a few months, then the fuel pump up and died, my luck it happened in the driveway outside the apartment. Now she runs better than ever, doesn't struggle to make power, starts with a touch of the key and then idles smooth when bone cold.

I must have been running with the pump being 25% or so down and the engine ultra lean because I was getting 30 MPG in the past. Now she is back to running on EPA averages. She does about 18-21 city, 23-25 MPG Hiighway and in "perfect" health now, according to my mechanic with a Tech-II scanner knock off.

ok I don't really have time to read all the other posts, just filling in my info. My 95 wasn't starting up right away and it wasn't even a priming issue. I didn't have the pressure needed for these engines. u need somewhere around 55-65 or something psi for it to run properly. I live in canada and i got myself a FPR(fuel pressure regulator) i opened up my cpi installed that and while i had it open i clean out( most of ) the carbon build up inside. put er all back together and runs wonderfully.!!!! read around here there is a topic with the instructions for it. Apparently the fpr goes on these vehicles easily!!!
