What is CSFI?
Central Sequential Fuel Injection (CSFI)
Where is the fuel pressure regulator on 4.3 V6 with central multi-port fuel injection?
It is under the intake manifold.
What is the fuel pressure suppose to be on a 1999 Silverado truck with a V6 engine?
The CSFI (Central Sequential Fuel Injection) system calls for 56-62 psi.
Where is the fuel pressure regulator located on a 1996 s10 blazer 4.3 vortex?
If you have the central injection system, you regulator is inside the plenum, next to the spider assembly. Takes about 20 minutes to get to it.
Fuel pressure 1996 Chevy 1500 4.3L?
There is 3 types of fuel injection TBI (Throttle Body Injection One Injector) 9 to 13 PSI CMFI (Central Multiport Fuel Injection) 58 to 64 PSI CSEFI (Central Sequential Electronic Fuel Injection) 55 to 61 PSI
Where is a fuel pressure regulator on a 5.7 vortex engine?
Vortex engine? Got me. I thought Vortex was just a brand of supercharger. I believe you mean Vortec engine.. GM also called this the L31 (they use 3 letter/number codes for everything) This system used a SCPI (Sequential Central Port Injection) system... and the fuel pressure regulator is on the central unit, which is INSIDE the intake manifold- you have to remove the upper intake manifold to get at it (plastic part), and the Fuel pressure regulator will be on one side of the central unit where all the fuel lines go to, it has a tube on it open to the intake manifold (to read intake vacuum)
Where is the fuel pressure regulator on 96 Chevy 4.3?
This engine should be CFI (central fuel injection) and the fuel pressure regulator would be under the upper intake manifold, attached to the "spider" (bank of injector poppets). The upper intake manifold needs to be removed to gain access.
What do the letters csfi stand for when used with a 4.3 L vortex Chevy engine?
constant ? fuel injection CENTRAL SEQUENTIAL FUEL INJECTION (LOOKS LIKE A "SPIDER")
What IS scpi fuel system?
From Drag Times, "Sequential Central Point Injection (SCPI)GM refined the CPI system into a sequential central port injection (SCPI) system in the mid-1990s. It used valves to meter the fuel to just the cylinders that were in the intake phase. " By all acounts, as much use as a cat-flap in a parachute, apparently .
What is idling fule pressure for a 1995 s 10 with 4.3 vortec?
With key on engine not running pressure should be 9 to 13 psi Engine at idle pressure should decrease by 3 to 10 psi on a throttle body. On a multi port injection key on engine not running pressure should be 41 to 47 psi. Engine running at idle pressure should decrease 3 to 10 psi. Central multiport fuel injection key on not running should be 58 to 64 psi. Engine running at idle pressure should decrease 3 to 10 psi. Central sequential electronic fuel injection key on not running pressure should be 55 to 61 psi. Engine running at idle pressure should decrease 3 to 10 psi.
Where is the throttle body injector on a 1996 Chevy Silverado?
The 1996 Chevrolet Silverado no longer came with throttle body fuel injection. It probably has the central sequential fuel injection system (CSFI) where each cylinder has its own fuel injector.
Where is the fuel pressure regulator in a 1994 Chevrolet S10 Blazer?
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.
