Please help with a push button starter install
Can someone explain how to get the crank signal with my push button i ran the wire off the push button thru firewall and connected to heavy purple solinoid wire. worked fine but on cold start had to crank **** out of it. if i just connect to the heavy gauge yellow wire from ignition switch and connect that to the wire from starter button will that give the ecm the crank signal its looking for? I have the manual and it shows the wire diagram for ignition switch that the Ign#1 terminal on the switch is connected at the crank postion as well as during run position which I know is the heavy gauge pink wire under dash seemed to me if this pink wire was connected to the heavy yellow wire to get signal direct that it would still be sending power to the solinoid with key in run position and thus still have solinoid engaged while motor started and harm the starter and flexplate. I know the manual says the pink wire is unfused and crank controlled but i wasnt sure what that meant. so basically I got the wire that triggers the solnoid from push starter button but dont know which wire to connect or wires to connect it to so that car starts good cold as well as hot. one thing i tried was to run a jumper from the heavy gauge pink wire to the wire red hot wire powering the push button starter button which worked. i got the crank signal and motor fired up quick on cold start but when i went to turn key off to shut down motor it continued to run until i disconnected my pink wire jumper from the power wire on the button. I'm using the red lighted button pep boys sells although i got mine from summit racing. it is a starter button that incorporates the needed relays and all into one button package so i dont believe i should need to add additional relays to make this work correctly. like i said before my first attempt at hooking all this up worked fine except for the first start of the day when motor was dead cold and it had to crank long long time. I do understand that connecting at the yellow wire right at the ignition switch channels it through the neutral saftey switch and such and i noticed on diagram that the yellow wire and pink eventually appear to meet up down the line at a point but i may be wrong about that. Thank you for any insight you can provide I know I'm on right track but I'm missing some small step that will make it work correctly

Re: Please help with a push button starter install
The circuit you jumped was the run circuit, which is on in both run and crank positions. you need to power that and the start circuit at the switch to get it to fire properly. So you will need a switch for ignition/fuel, and a button for start. The reason it takes so long at the solenoid is that the fuel pump relay isn't on. The pump also has a power source through the oil pressure switch, so it won't get fuel until you crank it enough to get the oil pressure up to close that switch.

Re: Please help with a push button starter install
So are you saying that I can continue to use the key and be able to turn it to run position and have motor fire well when it is cold as long as give power to the lg gauge pink wire. The pink wire i spoke of being "unfused and crank controlled" I kind of need it simplified for me 2 understand. I know my wire that will trigger the solinoid off my push button is to be connected to the lg gauge yellow wire coming off what would normally be ignition switch crank position. Are you saying I should also connect that trigger wire from button to pink wire also or give the pink wire power full time? Thanks for your reply I been losing hope someone would
Re: Please help with a push button starter install
I don't have a schematic in front of me, but the wire you powered that kept the engine running is what the ign. switch powers in run and crank for ignition/fuel. The other wire (yellow?) will only be powered during engine cranking and will be wired to your start switch. If you are unsure of what wire goes to the starter, jump power to each wire at the switch and see what one makes it turn. Don't worry about shorting anything, there are no grounds going to the switch. If you want to use the key for ignition, just wire your start switch to the wire you found for crank and make sure the key is on. If you don't want to use the key you will need to have an ignition switch wired to your crank/run wire (pink?) and a separate momentary push button for your start. Hope this made some sense.
