I filled my tank this morning and the guy topped it off after the nozzle clicked. car was fine then when i got to my freinds house i shut it off while waiting for him. when i turned it back on it read empty. i drove it and the low fuel message came on. tried to add more fuel but it was full. now as i drive the car it says im gaining fuel, almost if the sender is reading backwards. anyone had this problem?

 

do you still have a waranty?

 

kinda, got a stage 3 ecu, but they shouldnt look at that. could take it to the gmc dealer next to my job, but im a tech myself and would rather fix it myself....... dont like ppl workin on my car lol, but anything on this prob????

 

unplug your battery. this happened to mine but never again after i disconnected the battery. also tell that gas pump attendant to not ******* top it off! lol, in all seriousness when they top it off it could damage your EVAP system(depending how much they top it off) and get fuel into the charcoal canister which could mean that you would have to get a new one. make sure they dont top it off like that

 

thanks, ill try that. dont usually go to dat station, but i know bout the evap canister problems that can happen. thanks, ill try it right now

 

oh, i just read that your a tech. NJ sucks for not letting you put your own gas

 

hey how long should i disconnect the battery for? i did it for 10 seconds, but it didnt fix it

bump for an answer

bump

bump.......... any solutions?

 

You should let it sit removed for at least 15 minutes

 

Lol, I was in NJ two weeks ago, and I pumped my own gas.....

 

for rizziseal??

 

yea, its illegal to pump your own gas in jersey.......

 

I'm sorry, but really???

You're a tech and you have to ask that question?
