I have a 2000 chevy blazer with 141000 miles I replaced the fuel pump about a year and a half ago. In the last couple of weeks I have had to turn the key on and off about 6 times to get it to start. I hear the fuel pump running. I tested the fuel pressure with a guage before I hooked the guage up I tried to bleed the pressure off of the line no fuel present. When I turned the key on I showed about 20psi. When I finally got the pressure up to 60 psi it started. The pressure dropped about 7 psi. When I shut the motor off the pressure imeddiatly dropped to about 2 psi. Shouldn't the system hold some pressure. I'm hopeing it's not the fuel pump again. Could it be the fuel pressure regulator? By the way it is 4 wheel drive and has the 4.3 motor. Thanks Jim
