Push button start
Need help hooking up push button start swapped 01 Blazer to 5 speed and has sat for about 6 months not a daily just a project. Typically I go-to start it and get a click from starter if I turn the key and try to start on the 20th try it'll start. Cleaned connections at starter same click. My plan was to just jump the starter with key in run position with a push button. Tested that method and it started and ran. Tried it the following day and it will start and die in about 5 seconds with push button. Does anyone know why the push button now won't work as it was. Or if I possibly just have a bad ground somewhere causing the starter click when I use the key. Starter still works fine every time I jump terminals Blazer just stalls. If anyone has any input I'd appreciate it
I'm not totally sure what IOW means sorry lol. No I was trying to add one as a work around because sometimes the key doesn't work just clicks. Not sure if it's a ground issue or what. The key does still work but not consistent. Jumping the starter works Everytime but it usually kills fuel pump in about 5 seconds run time. I just want a consistent startup, I also had to connect 2 purple wires at the old 4L60 plug tricking it into park not sure if that's a issue. but it never was before winter when I did the trans swap, I had consistent key startup then. Just trying to do it as cheap as possible I wouldn't mind a button wired in even as a backup for the key click. Thanks for any help
I am going to assume that what you want us to put this back the way it belongs and get everything working correctly which we can do no problem.
The first thing you need to do is takeoff the battery cables from the battery, wire, brush, and/or sand, all the connectors, and then tighten everything back down. Then get a meter on those battery terminals and tell me what the resting battery voltage is and what the voltage is when you turn the key to start and the starter will not engage.
How do you know that the fuel pump dies five seconds after the engine starts? George .

Im assuming it's the fuel pump that cuts power when I jump the starter with the button when key is in run position figured it had to do with anti theft. And by push button as of now it's just a push button with alligator clips from harbor freight. That was just for proof of concept was going to wire it in straight to the starter in the future and it did work two or three times the first few tries I tried but after that it would start and then turn back off that's what made me think anti theft cut the fuel pump power or something I'll have to run to the store later to get a new meter cant seen to find mine
If it is a theft deterrent (pass lock) fault then the fuel injectors are being disabled not the fuel pump. After you perform the tests in post #4 then the next time you can’t start with the key, pull the crank fuse and measure the voltage at each fuse socket, meter black lead to battery ground.
