Im running an alpine amp for my rear speakers, all i can hear is my fuel pump noise, when i run gas, it doesn't make that noise, any ideas how to get rid of it?

I have similar problems with my Pioneer (unit and speakers) when I am out whoop whoop and attempt to use the FM radio all I get is interference. With the accessories (not ignition) on it recieve it fine, as soon as I click it once more I loose it all (if i disconnet the fuel pump relay the problem disappers).
I tried a number of different "cures" with no luck (the car dosnt run all that long with the no fuel), maybe the pumps motors simply generate excessive interference (there must be some way to isolate this???)
Sorry I cant help.

see im running it with my amp, could also be earth reading aswell.... now my factory front speakers are playing up when the car drives or moves, anyone can help me out?

Some one suggested that I should check the earthing of the system, which I did, with little luck (I attached additional wires) however this may work for you?

people been telling me to re earth it, ive also got rid of the fuel pump noise by placing the rca cables on the other side of the car, now what you hear is engine noise, im gonna give the earth cable a go tomorrow. Anyone got any suggestions?

there is a supressor for engine noise located on the coil (I think or maybe it is the distributor..). This may warrent replacement in your application?

i just replaced my power cable with a 6ga and also rewired my earth but still get thesame engine noise!, can anyone help me out?
