On the 4.3 vortec: to check for a leaking system, Remove plastic vortec cover, Then remove the round black thingy on the top and look in with a flashlight. It SHOULD be dry. If it is wet, you got a leak. Could be fuel pressure regulator (passenger side) or fuel line (driver side).
It already has throttle body fuel injection.
probably no because Chevy changed the type of fuel injection and it probably operates at a different pressure.
if you have cpi injection 54=62lbs if youhavetbi injection 9-13 lbs.
what is the diagram for a 4.3 Chevy blazer 1998 and the firing order vehicle is fuel injected
check ground first
It doesn't have a choke switch. The engine has central fuel injection (CFI).
No it does not.
Fuel pressure test.
Check under vehicle follow the fuel line from tank
On top of the fuel tank.
No there is not, Need to check the fuel pump relay and the fuse.
I had a Chevy blazer with the same problem. It had spark, fuel pressure, good battery & good starter. I sprayed some carburetor quick start spray & it started. They blazers have a problem with the fuel injection.
