3.2 MTX SHO
ok i checked it out and i got 543 for a CEL code and it says Fuel pump secondary circuit failure and it dont always come up its just randomly mainly when im lower on gas and when im low on gas it seems to once and awhile be a pain to start like dont kick over first tap of the key like it does any other time. does this mean my fuel pump might be going?
