Ok...i finally got everything installed. i ended up having to buy the whole spider because all repair kits call for the wrong fuel pressure regulator. for future reference though for blazer owners with the 4.3 vortec vin W...Motor Mite is releasing a part very soon (part #55162) that is actually just the fuel pressure regulator and will sell for $50. You will be able to find it in the HELP section at the auto parts stores. Anyway...back to my problem...the whole unit has been replaced now and the truck is still having a hard time starting when cold. Plugs, wires, cap, rotor and control module were replaced in April. Havent checked the rotor or control module but plugs and wires look fine. Could the control module or rotor be going this soon? or could it be something electrical that im overlooking? any help would be appreciated as this is my only transportation to work right now! Thanks guys.
