hey folks my 5.2 is having some starting issues will not activate at the relay to turn the engine over. new relay and starter. as of now AutoZone thinks its the wiring between the switch and the relay. I'm praying its not that because I really hate doing wiring. if anyone has any simple solutions short of running an auxiliary push button please share. right now I'm starting it by running wire straight from the battery to the positive side of the relay. also windows wont roll down... not sure if its a connected system or not.

 

Might want to check the neutral safety switch.

 

With key on, should be power on two wires at the relay. Is there?

 

is there a way to test that without a voltometer?

 

You can get a cheap test light. ...the kind that looks like an icepick with a long wire and an alligator clip. They are very useful and might be enough for your adventure here. But a voltmeter is a very good investment. I use one professionally. Along with a couple of expensive ones, I got one from harbor freight for around $35 and its totally adequate for anything related to automotive repairs and home wiring.

 

so I picked up a voltmeter and have no idea how to use it or even what numbers im looking for. I found the diagram saying what should have connectivity but it doesnt say what the numbers should be or what setting Im putting my voltmeter at. any helpful hints?

 

 

the window thing is what made it a little odd for me almost makes me think ive got two grounds conecting somewhere also what does the connecter on the side of the switch run to?

 

Check out Jaw91097's thread for pics of the PDC under the hood, and which terminals on the starter relay are which.

Also, apparently, I was incorrect, depending on the year of your truck...... The ignition switch sends power TO the control side of the relay, from there it runs to the neutral safety switch, and then to ground.

 

I second the neutral safety switch test. Pop the truck in Neutral and try starting.
