More then likely its the Canister Purge Solenoid. you can find it online at www.autozone.com the part number is PV140. And to replace it on blazer you have to remove the spare tire. Alot of people don't know where this part is so I hope this helps you and good luck.

SOURCE: my 96 chevy blazer has a code

my 96 blazer would have random missfires.... sometimes more than one cylinder at a time... there are a few things to try.... 96 vortecs still used distributor caps... but they had such a high intensity spark that they were well noted for frying distributor caps and ignition coils... i would start there... also a few times i had to replace the crankshaft timing sensor.... it could be something as small as a spark plug wire... i would start with the ignition before spending money to check the fuel system

I had that exact code a couple weeks ago. Mine needed new oxygen sensors. They(there are 2, only one was throwing a code, but I had both replaced) cost a little over $100 to have replaced.

P0440 - Evaporative Emission (EVAP) System .The most common cause for this code is a loose or bad gas cap.The running issue is unlikely caused by this.Is that the only code present?

SOURCE: if the p0440 codes come up is the car still ok to

Hi, P0440 indicates your computer is not getting a drop in fuel tank pressure when opening the evaporation system purge valve. This is not a safety issue, as the gas cap will release any excessive pressure, so you can still drive the car. The problem may be a leak in the evap system or a failed purge valve. Please let me know if you would like some troubleshooting steps or if you have other questions, and thanks for using FixYa.

How do you clear code P0440 after you change gas cap


if the gas cap was the problem it will clear it self in a week or two .Or you could take to the auto parts store and they will do it for free .You need need a reader or scaner to clear it I also have a 96 chevy and get this code from time to time it means that there is a small leak someware in the EVAP system or some times it sets off falsey . This system runs 8 differant self tests everytime you start the vehicle . But P0440 isn't a code to worry to much about it won't damage your vehicle in any way

P0440 trouble code 98 chevy blazer


This code indicates a leak in the fuel vapor system know as the evap system this can be caused by several things. a faulty purge valve, a vent valve, any one of the fuel vapor lines or even a gas cap that is lose or the seal is bad on gas cap. to isolate the exact problem requires a high end scan tool and a smoke machine to find the problem. on this vehicle the two most common problems are a gas cap, or a bad vent valve
