Cheat Engine

[crashoverride93]

Hello I am aware that this is a pretty old pc game but none the less I am playing it and I have found the value for the damage var pretty easily but can someone give me any Ideas on finding the value for the fuel bar. I know it runs out of fuel after you drive long enough. I know that the damage bar was actually more of a health value for the truck as it was a float value and decreased as you hit things the damage bar actually filled up as the health of the truck decreased. But please help with the fuel somebody I cant find it.
UPDATE: Now I have actually found the value but have no Idea how to find the pointer too it. Also if anyone can someone also tell me possibly how to hack the noteriety bar.
Even Further update the reason I cant find the pointer is because when I try to do what the cheat engine tutorial taught about it pointers it seems to find the wrong pointer leading to a diffrent address. Another Update on this I have gotten the concept of pointers in the tutorial I think and have found two address pointers that seem to work everytime the game is restarted and those two are money and rig health meaning 100 on health means no damage to rig and I found pointers to other things to but they dident work on restart.
