Does a '96 GMC safari have a fuel pressure regulator?
yes it does! It inside the upper intake! It conected to the cpi!
Where is the fuel pressure regulator on a 1995 Chevy 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
Where is fuel regulator on a 1994 s15 4.3 liter cpi engine?
The fuel pressure regulator is located under the upper intake plenum, attached to what is sometimes referred to as "the spider". It is not uncommon to find one or more of the individual plastic lines have cracked due to being exposed to the heat under the upper plenum or for the regulator to leak, flooding the manifold.
What is a Blazer fuel pump start up pressure and engine running pressure?
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....
Where is the fuel pressure regulator on a 2000 Chevy blazer?
If your engine is a 4.3L V-6 with CPI (central point injection) it is inside the upper intake manifold. The upper intake manifold is bolted on top of the normal intake manifold. The throttle body is mounted on it and your fuel lines terminate into the center of this.
What would cause a 1991 blazer with a 4.3 tbi to DUMP fuel into the engine?
sounds like a bad M.A.P. sensor I would like more information. There is many causes for this yes a MAP sensor or a problem in the MAP sensor circuit is possible. If this is a TBI fuel system and NOT CPI fuel pressure is regulated by a regulator in the TBI unit. If it is a CPI they have a totally different problem fuel supply or feed lines a usually cracked inside the plenum. If you want to E-Mail me at hytec9@charter.net and I will try to help after get more information Thanks
Is there a fuel diagram for a 94-95 blazer with cpi 4.3 vortec?
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.
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.
What is the most common failure of the 4.3 fuel system?
weak fuel pump or fuel lines leaking under intake penilum or fuel regulator or injection unit (spider itself) and or plugged injector tubes. (94 safari 4.3 CPI injection)
What would a 1993 S10 Blazer 4.3 vortec cpi not start checked fuel relay works fine checked fuel pump works fine replaced oil pressure switch started good for 3 days ran good now will not start?
got spark?? Need to check fuel preasure with a gauge, it should have 9 to 13 LBS of preasure no more , no less CPI needs 55-61 PSI fuel pressure, 9-13 works with TBI
Is there a common or frequent problem with fuel injection or sensors on a 1994 S-10 Blazer?
Absolutely. The problem is common with all the GM vehicles made between 1992 - 1995, that have the 4.3L Vortec vin code "W". The 4.3L Vortec has a CPI (Central Port Injection) system that has proven to be quite problematic. These injection systems consist of a large fuel injector that has tube going to each cylinder (six total). This injector is located in the plenum. (must remove upper intake to see it) The problem with these systems is that they develop leaks, these leaks occur in either the FPR (fuel pressure regulator) mounted on the side of the injector or the internal fuel lines leading to the injector assembly (GM has decided to refer to these internal fuel lines as a "Nut Kit" for some reason). The FPR is located on the passenger side half of the intake, and the nut kit is located on the driver side of the intake. The cylinders on the side that develops the leak, get flooded by fuel causing a rich condition. This rich condition can cause the engine to run rough, create a strong smell of raw fuel, set O2 sensor codes, cause excessive carbon build up that plugs the EGR valve, set EGR codes, and/or cause raw fuel to enter the oil which destroys the engine. I will add links to the right that have more information about the problem, and detailed instructions on how to fix it. Look for "92-95 4.3L Engine info", "4.3L Vortec CPI and Nut Kit Replacement", and "4.3L Vortec Fuel Pressure Regulator Replacement"
Have s 10 blazer instead of fuel it get air. fule sometimes cpi fuel inject?
It should get both air and fuel.
