I have a 1997 Gmc Sierra k1500. On the way home from work it drove fine. I backed it into my driveway then shut it off, got out and decided to back up some more. Went to turn the key and nothing happened. I have battery power but engine will not crank. I checked fuses thinking that may be it. I found one of the 40 amp ing. Fuses blown under the hood. Changed it out but still nothing. I also changed the starter relay thinking that may be it but still no luck. Any help would be appreciated.

The purple wire at the starter solenoid should be hot with the key in the crank position. If it isn't, check the circuits at the starter relay. Any starter testing, make sure the tranny is in park or neutral and the e-brake is set.

Ok, that is a little above my talents. I was hoping for something simpler.

Will the vehicle crank in neutral? You could use a testlite at the starter solenoid S terminal, purple wire, while helper turns key to crank. If there is voltage, the test lite comes on.

You can pull the starter off, some of the national brand autostores will test it for you. Also could be issue with neutral switch? Hate to see you throw parts at anything, need to test.

Whats the easiest way in noob terms to get access to the starter. Right front fender well to the rear of the engine block? Is this the correct location? Hard for me to get to it if this is it. Can someone break down the easy method of testing. Please and thank you
