recently been having some problems with my truck. first the gas gauge didnt work so i replaced the fuel pump and after that the fuel gauge has a mind of its own and i know i connected everything properly. also it will sometimes sputter when im doing about 45 coasting then hit the gas it will buck back and forth then finally get power. just recently changed the purge solenoid so hopefully that fixes that since i got the p0440 code. also i was told i could reset them pcm by removing the ecm1 fuse and ecm b fuse but i cant for the life of me fint the ecm1 fuse!!! any ideas?

 

Not sure what model and year of truck; however, just pull the negative battery cable, it will do the same as removing a fuse.

 

ive got it all reset. now my main issue is the gas gauge. ive got a new ac delco fuel pump with new connectors and it seems like the gauge responds to me pressing the break. when i do that it will go from full to e. gauge will also do that randomly. any ideas?
