Hi, bought a new fuel pump for 2003 cavalier old pump had a square plug on the harness to fuel pump new one has a GT280 flat plug, it came with a new flat plug harness to replace the square one wire colors don't match old plug. A is purple B is gray C is blk D is blk/WHT new flat plug is A is orng/blk B is try C is ppl D is blk I would like to wire it correctly any correct input is greatly appreciated

 

did the pump come with any documentation to tell you which wires are for what?

 

Hey mountainman, there is a small book that came with it. it has a couple different combinations but none look exactly like mine..I watched a couple you tube videos none were consistent some say don't worry about color combination just connect A B C D to A B C D and then some one says just the opposite?? And I really only want to do it once if at all possible!! Maybe I read to much and over loaded my brain which until recently I thought still worked fairly well!!

 

can you post the info please

 

Info from new precision fuel pump #

Info continued, # 2 from precision fuel pump new harness plug Gt280 let me know if this worked or helps, thank you for your responses DD4518511

 

This should be your existing plug.
(B & C are for pump motor, A & D are for the level sensor)

Sorry mountain man yes you did reply! I just haven’t been able to get back to it, have a lot on my plate at present. Been painting and helping a sister get moved into her new house 10 hr days with another 2 hour commute, am trying to get this fuel pump job changed for another sister thought it might be a half day job! Plus a few other unexpected things popping up all at one time!! So again thank you for your help and responses I do so much appreciate It… will let you know outcome soon as I can get back to it…

 

Not done helping one sister move yet but did get time to get new fuel pump rewired and all put back together!! Started right up fuel pressures all good! In fact my sister drove it away from my house this morning!! That makes me happy!! So a very appreciative thank you to mountain man for your help, quick responses and understanding of a couple replies when over tired! Again thank you...Derek
