thats good to know. a friend of a friend can help me out with the scanner. what sensor did you end up having to replace?

 

Fuel tank pressure sensor. Located on top of the fuel tank on the pump assembly. Yours is acting just like mine did. The code mine threw was TPS input low. I dont remember what the number was. SWARTLKK is right! dont replace the sensor unless you go through the troubleshooting sequence. I threw a TPS code but the sensor wasnt bad.

 

i also had the tps code but i recently replaced it and its now gone. i am gunna try to get it hooked up to a scanner tonight, if i do i will post results.

 

My TPS input low code popped up as soon as the truck started to lose power going down the road.

 

welll.... i still havent gotten to do anything with the blazer... is there a way i could test my fuel tank pressure sensor without getting it on a scanner??
