Fuel Pressure Guage
My 2001 Xtreme blazer ... It has spark, it has fuel pressure, Starter is fine ? ?
I have been trying to trouble shoot my blazer .. I figured out that I do have SOME fuel pressure ( I took the cap off of the shrader valve and had my wife turn the key with I pressed the center). I do have spark ( I took a plug wire of of a plug , stuck a screw driver in it and put it next to the engine. It DID arc ) My starter seems to be strong and my battery WAS strong until I tried 1 zillion times to start it. What could it possibly be ? ... also where can I buy or rent a Pressure guage and how much ? Thanks in advanced

PLEASE HELP ??? =] ...
Fuel pressure gauge is what you need.(A MUST for diagnosing)
Putting your finger on the shradder valve to see if you have fuel is no indication of fuel pressure.
your truck's fuel pressure needs to be at or about 60 psi not 40 as others have advised, anything less than 50 psi it will not run. NO need to disconnect vacuum line to regulator as regulator is inside upper intake plenum and has no vacuum line to it.
The 4.3 does not have a timing belt, it has a chain, I have yet to see one jump timing.
Your problem is fuel pressure. Hook up the gauge and turn the key ON OFF ON OFF then ON (by doing that it's building up pressure ),
then read the gauge, it needs to be at 60 or about.If not replace the fuel pump.
