I have a 87 Irocz, and when i turn the key to the ON position the fuel pump turns on for a second to two. THEN if i hit the brakes the fuel pumps turns on for a sec or two. It does this every time i hit the brakes. Is this normal????? Thanks Shane.

Sounds a bit goofy but probably nothing to worry about...

Theirs alot of ways to make electronics do funny stuff from feedback.

Back in school we had a chevette that i figured out how to make the windshield wipers move with the turn signals by turning on certain combinations of things...

Re: Is this normal???

Well the only thing i can think of is: i took aout all the lights behind the gauges because i instaled glow gauges, code alarm about 4 years ago, and 2 auto meeter gauges in the A piller also about 2 years ago.



I FOUND A BAD GROUND. THIS IS WHAT IT DOES NOW: TURN THE KEY TO THE ON POSITION, FUEL PUMP TURNS ON FOR A SEC. OR TWO,

NOW IF I HIT THE BRAKE IT TURN ON ONE TIME, IS THAT NORMAL TO DO THAT ONE TIME??? BEFORE THE FUEL PUMP CAME ON EVERY TIME I HIT THE BRAKES.
