i will have to tell all the story so someone can give me the good answer
boat at the begining of the season runs great
then one day when i returned from the other shore of the lake , i was a great condition lake to try at full throttle the boat , the lake was a mirror
i was going very fast then , engine make a backfire and stalled
first i thoutgh that i blowed the engine
then i try to restart and it start good
but because i was affraid of brke the engine and not getting home
i go very slow to make sure that i go home safe
at home i checked the compression
210 230 230 230
230 230 230 210
its a 454 bbc crank 500hp
then one nigth want to go whit my girlfriend for a little ride
start the boat
go iddle to the lake
the hit the pedal and after a couple of seconds
it stalled again at high rpm whit a bacfire
went back home , look for electric fuel pump
the magnet were not good
so change the fuel pump
holley electric blue
check ground ..... wire .....
go for a ride and same thing happen
i have to mention
when i put the key switch to ignition i hear the fuel pump
then start .. the engine runs great at iddle
when hit the pedal and stall
the electric fuel pump is stoped at the same time
then i can hear the fuel pump getting powered again
can it be a short wire ?
the fuel pump is suppose to stop at the same time that the engine stall ?
im asking this because the power to electric fuel pump is suppose to be there even if the engine stalled
can it be a bad key switch ?
