hey,

so the situation is my fuel pump fuse keeps blowing on me everytime i turn the key on since i have swapped out a ka24e for a lower mileage one. before the swap it occasionally blew the fuse but now it blows it when the key is turned on. it blows a 10amp right away. and a 15 lasts long enough to start it but then it burns out and dies.
any ideas anyone? i have checked all grounds and they all are tight and look good. and i don't know where else to check

thanks for any advise in advance

 

have you check the engine or the motor?Maybe there are some rusty parts...

 

rnThis new fuel pump that I have requires a 5 amp fuse. Ive wired a relay so that the pump only gets power if the key is in ignition. Like this:
rn
rnrelay: use a 30amp-40amp relay
rn30 - battery - 20A fuse
rn85 gnd
rn87 to pump
rn86 ig feed make sure its full12v when starter motor is cranking
rn
rnDo I wire in another 5 amp fuse between the 87 and the fuel pump, or can I change that 20 amp to a 5 amp fuse from the battery?rn
