Crank fuse ?

 

If that's ok , check purple wire at solinoid while cranking with a test light , check battery connections etc etc

Also make sure neutral safety switch is working properly. Try putting shifter in neutral and see if it cranks over. If you are not getting any noise from starter at all, it usually means the starter is not getting the signal to crank over(12v applied to purple wire at starter).

 

What happens to the dome light when you try to crank engine over? Does it dim, go out, or no change at all. You can also try turning headlights on and see what effect trying to crank engine has on brightness.

 

Do not fall for the "but battery is new" logic. New parts come with a warranty for one reason, sometimes new parts are bad. Verify voltages while sitting, while cranking(or attempting to crank), while head lights are on, etc..

 

As already stated, check all battery cables, at both ends, for connection tightness and cleanliness. Check the actual connection of the cable end to the actual cable. Sometimes they will corrode under insulation at the crimp, especially the aluminum or soft metal ends of cables.

 

When was the last time this engine ran? Does it turn over if you put a socket on the balancer bolt and turn engine manually with long bar and socket?

We have been driving this sub for a while, a few days back this started happening, we went out to eat and it had trouble cranking, finally started, with old battery, but then we came home and the next day nothing would crank, no sound no nothing, we already knew it was time for a new battery so we put one in, as we drained the old one to try to start it. I am no mechanic by any means but I just want to get this darn thing running again. LOL. it raining out today we live right by the beach so maybe something has corroded along the way, as it sits out in some nasty weather here. cant find where the darn starter is.?

I tried putting it neutral and nothing still, does not effect the lights whatsoever. ?

not knowing where the starter is means its got to go to the garage as there are to many things to guess at for you to tell your mechanic

 

sorry its what i feel needs to happen

      AUX switch install

      By SwitchBladeSierra · Posted

      Update for anyone following:    Installed everything as shown in diagram. Opted for 8 AWG from Battery Positive to a 50A resettable inline breaker. 8 AWG is tied into to 2x 12 AWG wires feeding a 6 way fuse bus in parallel (manufacturer’s design of what I purchased).    4 of the 6 fuses available for circuits are tied to terminal 30 of each relay. I tied a jumper from one of my spare circuits off the bus to terminal 86 of each relay. The trigger, terminal 85, was pulled from my interior by way of T-Taps from the X61A-X5 pins 10, 11, 17 and 23. This was the hardest part of the job. Even with the X61A unbolted and the X5 removed - there was VERY little wiggle room.  I added back up lights that I want to come on with my cargo lamp - but when I would check continuity between S48A-X1 pin 18 to its respective landing point on the X61A-X5 it triggers the factory relay… Instead I opted for a add-a-fuse on the passenger interior fuse panel (fuse location 10 - cargo lamp) and ran it through the boot on the driver side to my load. Did this to avoid introducing any electrical gremlins.   Note: Please check for continuity between the S48A-X1 and the X61A-X5. In my case wire colours were not the same as other’s who have posted. To do a continuity check you need a Multimeter. Completely disassemble the S48A-X1 and remove the brown face plate off the X61A-X5 by way of a flat head screwdriver - this was the only way I could get any results.   The outputs, terminal 87 of the relays, were fed into a junction box and landed at Individual studs and were labelled Aux 1-4.    At this point, all you need to do is run wire to your loads and bring them to ground. I created a negative bus in the engine bay, all my negatives land here.    For anyone having issues with all of your new aux switch lights coming on with the press of one - I noticed this only to be an issue when the battery wasn’t hooked up to my relays? No idea why, but it was quickly corrected by having my system buttoned up and functional.

Thanks GM lol

      Don't need the air tube but that's how everyone sells them. Most places won't remove that one piece and sell it alone. No money to be made. Hoping someone swapped theirs out for a CAI and no longer wants it. Not asking anyone to give it away. Offering to buy it but I don't need the tube. It's held on by a hex head screw and nut. Been all over eBay.
