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"
A 1998 Chevy S10 Blazer has a total of two oxygen sensors. One is used for the upstream and one for the downstream.
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.
If it is equipped with air bags of course it has sensors.
central port injection
It already has throttle body fuel injection.
I had a similar problem with my 95 Blazer. The problem I had was with the spider unit or the fuel injection unit. This went bad on me along with the fuel lines going to it. While I was driveing one day it just died. If you have gas in the oil this could be your problem.
A 2002 S10 Blazer doesn't have throttle body injection (tbi).
No, they will need replaced if defective.
yes a 1993 4.3 liter motor can have (cpi) centralport injection) (spyder injection) if your blazer has a (w) has it 8th vin letter then yes it does but if it has a (z) from a 8th letter on your vin number iz a (tbi) throttle body injection
if you have cpi injection 54=62lbs if youhavetbi injection 9-13 lbs.
It would bolt in but you would have fuel injection problems.
There are 4 sensors on the 1995 Chevrolet Blazer. The 2 front for the Disc Brakes is behind the rotors on the hub. The inside hub has gears and the sensors are above them. On the rear, where you have Drum Brakes, the sensors are on the back of the Drum Brake Assembly, next to the bleeder screws.
Passenger side, in front of the starter.
Assuming this is the 4.3L engine, one.
In back of engine, it can be reached from the top.
That vehicle has several O2 sensors and they are all threaded into the exhaust system at various points.
I have a 1999 Chevy blazer 4.3 v6 we just replaced them there is three two up stream and one down stream. If you get under there and look you will find them with no problem. I'm a woman and I found them with no problem. two on passanger side one on drivers side. unless you have two catalitic converters then there is 4
There are four o2 sensors on a 1996 Chevy blazer all on the exhaust, of course, there are three ahead of the convertors and one between the convertor and muffler. on the right hand bank. should be changed every 60,000 miles.
They are in the exhaust pipe system, There are none after the muffler.
how many oxygen cencors does the 1994 Chevy blazer have
trying to fix simular problem
I have a code DTC P0154.Bank 2 Sensor 1 no activity.Which sensor is this on my 96 Blazer?
probably no because Chevy changed the type of fuel injection and it probably operates at a different pressure.
