Question about 2001 Chevrolet Blazer
Hi, I have a 2001 Chevy blazer that broke down about a year ago, i hav replaced alot of different things and the vechile is still broke, I am now down to the most exspensive parts and need to figure out which one it is. My blazer will not start it will only turn over and over tll the battery dies. I have replaced the starter the alternator, the fuel regulator, the fuel filter, the temp sensor, the ignition switch wires. I did a fuel pressure check and when you turn the vechile over it reads 60-65 pounds of pressure, however when you shut it off it drops down to 40 pounds. I also used a noidto check he injectors and the wire part seems fine.
The vechile will start hoewever if I dmp starting fluid or gas in the air thingy it will run till all the gas is gone, I'm thinking this is a fuel problem, I just need to find out if it is the injectors or th pump. The pumps whines, and puts off enough pressure, could it really be that?
The fuel pump has a rubber line about an inch long between the pump and fuel lines which i have found in the past 9 years as a mechanic to cause these problems check this first then if this is not the case put a fuel pump in.

Sometimes a defective Fuel Pump will run and operate as normal and give you the correct pressures before start up, but can't work fast enough to keep up with the demands of a starting, or running engine. Engine's take a high demand on fuel for startup, its a short period, but a high demand nevertheless.
My opinion is that your Fuel Pump is faulty, Not completely broken, just unable to keep up with fuel demands. Try replacing your Fuel Pump, and while you're at it, be sure to check the lines in the Gas Tank itself for frays, holes, or rips. As that can actually cause the problem too, but is VERY easy to over-look it, as fuel can squirt out of a pinhole at 60psi
