General ChatChat about all things Blazer (and related vehicles). Off-topic stuff should be in the lounge, and all mechanical problems should be posted in the proper forum.
Freezing my a$$ off all night getting this dang blower motor out and also the relay and resistor. Luckily I made it to Idaho from West Virginia with it working. Otherwise would've froze to death. Haha
I've done that job before. Being able to see it from the engine compartment, you'd think it would be easier to replace than it is!
Just finished repairing my stuck electric drivers seat. (2001 ZR) Had to remove the seat and replace the cable between the two gear boxes. (Among other things)...
I’m posting it on forums about Chevy blazers also an upgrade fuel pump will be install soon also don’t reply if you don’t have an answer.
Your closed loop fuel management system will use the O2 sensors to monitor oxygen content in the exhaust and continually modify the fuel injector pulse width to maintain minimum emissions by maintaining the air fuel mixture as close to 14:1 or stoichiometry as possible. Your engine computer will fight any attempt to increase fuel injection volume unless you are tuning for performance and increase air volume or volumetric efficiency. As far as the fuel pump and rail pressure goes that is regulated by the intake plenum regulator not the fuel pump output capability. Your question might apply if you were building a higher horsepower motor with say a turbo or blower and needed more fuel volume and then you would need new computer maps, etc.
Welcome to the forum but watch the insults or you won't get the benefit of the knowledge here. I could use the same attitude regarding not providing enough detail in the question to be able to give a proper answer.
