I have a 2000 GTP with 171,000 miles on it. I had a strange thing happen the other day. I was low on fuel so I stopped at the gas station and turned my car off to get gas. The pump's card reader wasn't working and I had my dog with me so I didnt want to run into the station to pre-pay for the gas. I thought I would just move to a different pump, but when I went to start my car it would crank and act like it was going to pop off but wouldn't fire up. About ten minutes of sitting there I decided to try again and it started right up. I let it idle for about 15 minutes while waiting for my brother to stop by to follow me home. I drove home a couple of miles with no issues. I checked the codes and had a 0440 and 0128 which have been there for a long time and come and go.
Any ideas of what could be going on? I changed the CPS, fuel filter and MAF about 2 months back so I have pretty much ruled them out. Could my fuel pump have overheated or vapor locked due to low fuel level in tank? Could the fuel pump be going bad? When I turn the key on I hear the pump start and it sounds normal. I was going to test the fuel pressure this weekend. What would be a good pressure range?
Thanks for any help or ideas. I am hoping someone has had similar issues and can point me in the right direction. It could have been a one time thing but I want to make sure since I am often hauling my kids and it can get cold during a Minnesota winter.
Sorry for the long explanation, but I wanted to get it all in right away.
Thanks, Chad
