Pennyman after seeing that I found a 75amp for $37 shipped on ebay was rather ecstatic lol

But it seems my truck is having a new issue every week it's something else acting up or failing for 3 days now I've just fought threw it I can crank and quickly let go of the key the truck fires right up sometimes it won't even do that and I'll have to leave the truck in the run position get out push it jump in dump the clutch and it will start but won't start via the key? All it does is spin over and over so I'm assuming with the key in start position I'm loosing spark? Or somthing is messed up with my ignition switch......

From what I could find via Google everything aims to my ignition switch but I couldn't find a replacement anywhere.So I'm kinda out of ideas at this point I can't keep bump starting it everyday it gets rather exhausting lol.
