When you say it won't start after a couple of days do you mean it will crank over but fail to "catch" if so you then have got to determine if is fuel or spark you are loosing.Or do you mean it fails to start because it won't crank over like a defective starter, battery or ignition switch circuit problem?
it cranks over but wont start up like i said I replaced fuel pump fuel filter crank sencer and both oxygen sencers. could the computer be bad??
