Re: 5.3 Ignition starter wiring

I suppose that's possible, but I wouldn't know why it wiuldn't be putting out enough power, since you said you didn't do anything to it and it has been starting the truck for 40 years? Put a voltmeter on the purple wire and have someone crank it and see how many volts you're getting. Maybe you've got alot of resistance in your ignition switch?
