might be a clogged fuel filter
Try cleaning out the walls behind the throttle plate and cleaning out the injectors. ------------------------------------------------------------------------------------------------------------ Or you can try changing out the MAP sensor, or IAC (Idle Air Control Sensor)
central port injection
you need at least 50 psi to run and 55 or so to keep it running thats with cpi engine the others use less pressure and a different fuel pump....
There is a fuel diagram for a 94-95 Chevy Blazer with a CPI 4.3 Vortec engine in the service manual. It shows the path the fuel travels from the fuel tank all the way to the injectors.
Next to the distributor
1,6,5,4,3,2 same cpi engine as an s-10 blazer
if its a cpi it would be in the the middle of the intake as part of a injector assembly on a 4.3L
It should get both air and fuel.
if you have cpi injection 54=62lbs if youhavetbi injection 9-13 lbs.
THERE ARE TWO MOTORS FOR THE 1994 S-10 BLAZER. TBI (Z MOTOR) AND CPI (W MOTOR) Central Port Injection Throttle Body Injection. IF IT'S CPI THEN IT'S UNDER THE INSIDE OF UPPER INTAKE MANIFOLD. IF IT'S THE TBI MOTOR THEN IT'S ON THE THROTTLE BODY.
Chained CPI is 0.3% less than the Normal CPI.
If the CPI or Consumer Price Index rises the prime rate will stay the same, but may be adjusted to reflect the state of the economy. An instant rise in the CPI does not equate to an instant rise or decrease in the prime rate. The prime rate is adjusted after several economic factors are reviewed.
