ive been having problems with my lude starting but in the past it would have charge and make the sound of ignition,, but a faulty fuel pump or relay would have me thier for a while trying to start it.... but now it wont even make the ignition sound all that happens is the dash light turn on and power windows work but the charge is not thier...i think it might be an old alarm system that it has that hasnt worked in a while ..but not sure what to do.... the lights blink out of control like thiers a short ....any advise??
