EFI fuse keeps blowing

[majic]

I have a 04 v8 and the 10amp efi fuse keeps blowing causing the engine to die. I replaced the fuse with another 10amp fuse and it lasted about 2 weeks and it blew again. This time I put in a 15amp fuse and it didnt last but 10 seconds. Any idea?
Thanks

I would check all connections to this circuit for water/corrosion and start disconnecting all additional consumers but ECU and and check resistance of all related wiring to this circuit also.

Fuse

I would use a multimeter to see if that circuit has any continuity to chassis ground. Basically, put one lead on a grounded bolt and the other on the circuit. If you DO have continuity then you have a short in your wire.

Thank you for the replies, ill try those out when I get home tonight. This is extremely annoying, I thought I had the problem figured out about a week or so ago and now its back to blowing fuses again.
