Hello jess22smo: My name is Roger and I will help you. The answer to your question is yes. You will need a special tool to remove the power steering pump pulley. You might be able to rent a tool from the parts store where you buy the pump. Orielly's offers this tool option. or you might be able to rent one from a tool rental. You will also need a tool to reinstall the pulley to the new pump. Should you need further help please just ask. Please rate the answer this way I know it was helpful. Thank You for using Fix Ya.

Hi:
The fuel pumps on the Chevy blazer and their full sized trucks are prone to failing, as I had to change mine on my 1996, and yours is the same model .
Ours started off intermittently dieing, then failed all together. If you have matched up the fact that you have no fuel pressure when your blazer won't start, then the fuel pump is the most likely suspect. As you know, they are not cheap, and the fuel tank is not difficult to remove, but needs to be close to empty to make the job managable. The tank is over 3 feet long, and is better removed with 2 people if you can find help.

If memory serves those have high pressure clamps that require spec. tool it comes in 2 pieces you snap together around clamp to pull apart
they used to rent them at part stores

sounds real easy either a bad idle air control solenoid or more likley a blown throttle body gasket. to test fro a blown gasket, with engine running and cool spray carb cleaner or brake cleaner around base of tb were it bolts to intake. when it hits the bad area, should idle down and be normal for a second or 2. iac is possible,try this first since its so common and let me know

are you sure the pump you installed is not defective it does happen more than you can believe. If you can run a power to the pump hot line or jump the relay and have a ear to hear if it is pumping, this is what I would suggest.. Good luck

try fuel injectors and ingnition coil

hello did you unhook your filler hose ?

an automotive shop should have the tools u need its a little plastic thing that goes over the fuel line and releases the clip inside the filter
