I have a 97 Chevy Blazer that will crank but not start. I can get the vehicle started with the help of starting fluid or gasoline put in the throttle body but throttle response while driving is poor. ...

if it starts with starting fluid. its not getting any fuel to engine. first check the fuse and relay for fuel pump. then make sure fuel pump comes on when you try to start it. its only on for a few seconds when starting. then when driving its on all the time. good-day ! fuel filter also if need be.

My 1997 blazer won't start unless primed in the throttle body it runs fine after when shut off for a day it needs primed again

This sounds like a fuel pump is starting to fail. The system is designed to keep, or at least prime rather quickly to allow for efficient starting. If the pump is begining to fail or, has a plugged fuel filter (which will kill a fuel pump), it may create this issue. One other item to check is the coolant temperature sensor. If it is reading warm when it is cold, this symptom will occur.

96 chevrolet blazer 4.3 when truck sits over night it cranks over for 3-6 seconds before starting. will start a little quicker if gas pedal is slightly pressed?

There are several common fixes for this problem. Fuel spider is one, fuel pressure regulator is another. However, the most common and likely is your fuel pump module assembly. The fuel pump has to be able to hold pressure from the fuel tank all the way to the regulator. It works just like a foot valve on a well. When it goes bad it let's the fuel in the lines & fuel filter bleed the fuel back to the tank when not in use.when you try to start it after it sits, the fuel has to flow all the way back to the engine. Although the fuel pump is the most expensive of these items, more often than not, that will fix it. Fuel filter should also be checked and replaced if installing a new pump.

My blazer has a new fuel filter, egr valve and

As a quick test,fill-up the tank and do not top off.

Monitor the starting problem.

If you're starting OK until BELOW 1/3 of the tank then it's a weak/failing fuel pump.

Mass air flow (MAF) senor provide air temp/density to the computer.

Buy a can of MAP cleaner and follow the instruction on the can.

Hard starting, excessive crank time

try changing the fuel filter and turn the key on and off several times before starting engine. once running check the vaccum line on the fuel pressure regulator.the regulator can leak fuel from that connection.
