1996 chevy blazer heavily misfiring

I have a 1996 chevy blazer 4.3l v6, the fuel pump went out and i had it replaced as well as the fuel tank , and fuel filter. it ran fine for about a week and then just wouldnt start after parking at work. i had replaced the MAP Sensor and the mass air flow sensor before it would start again. once it started it runs really rough, and is undrivable due to absoluetly no power.. the computer read that cylinder 3 was misfiring. i checked for spark and changed the plug in that cylinder.. no change.. someone told me it may be the coolant temp sensor so i replaced it. a noticable change in idle, not misfiring as bad but still undrivable due to no power. when you put into gear the engine begins to stall.. the plugs were changed approx 3-4 mnths ago. it is not driven heavily.. if anyone has any other suggestions on how to resolve this please help. since it is undrivable i will have to have it towed anywhere to get a diag done on it. i am trying to avoid the extra cost.

Check to see if the oil cap is on tight,it wont run well if it is off or not tight...if it smells of strong gas fumes then replace the fuel regulator,the catalytic converters could be plugged,let it warm up as much as you can and use an infrared thermometor with the laser light(you can get at Home Depot for about $30.00)and check the temperature of the converters by aiming it at it and the temperature should be no more than 1500 degrees...or pull the distributor cap off and inspect for cracks and corosion..

I always tell people to start with the basics when trouble shooting problems this difficult to repair. #1 get a note pad/book to log everything you do Date, Part, Test, Results, Notes, Etc. and keep all of your old parts until you are convinced that this repair was 100% successful. #2 Buy a service manual for your vehicle at the dealer, it will help you with details of how to do every fix on your truck. #3 Start testing by doing a compression test, if it has no reading or leaks down, put two squirts from an oil can into the cylinder and test again, if that helped you have bad rings, if it didn't help you have a leaking valve, #4 set the timing and check if the advance is working right, #5 Empty the fuel tank and put 5 gals fresh fuel, Test your fuel pump to empty your gas tank. #6 Check your fuel injectors to see if they are clogged up from the first problem you had. #7 Check and replace all of your vacuum hoses #8 Check your coil for proper output. #9 check your plug wires, rotor, cap, replace parts that look suspect, check timing again. #10 Check for oil in your radiator if the compression readings were low on one side. After doing all this come back if you still have the same problem.

Changing fuel pump for 1996 chevy blazer


Whats the problem? To change the pump you must drop down your gas tank. Make sure it is as empty as you can get it though! Once the tank is dropped you need to twist the retainer ring (usually with a screwdriver, and make sure its got some tape on it so it wont spark. then you can replace your pump.

Hello,
Replacing the sending unit / module is optional when its a metal top module. If it's plastic I would replace the whole thing reguardless.

The fuel pressure valve is draining the fuel back into the fuel tank when the Blazer is parked.

They should be on seperate circuits. Tyour key on and ck to see if you have any fuel flow. Fuel pumps in tanks do **** out. chk to see if you have any fuel flow by loosening a fluel line. No fuel, no pump. good luck
