Push button start help

[YungICY]

I just finished installing a push button start in my 85 2.3 ranger. Everything seemed to be working good until I drove around the block.



Air fuel ratio gauge shows a lean condition and the motor is being a little sporadic.



I have everything hooked up as follows.



1 on/off 20 amp toggle switch. Hooked up to all "run" wires (1 black, 1 blk w/grn, 1 brn w/pnk, 1 red w/grn, 1 prpl w/wht, 2 red w/wht, 1 gry w/yel, & 1 yellow power wire.) There was also one more grey with yellow wire that I did not hook up. All of these wires are crimped together with 1 10 gauge wire hooked up to one side of the switch minus the power which is hooked up to the other side.



I assume somewhere in that mess is my problem.



1 20 amp push button starter switch with 1 red w/ blue wire and 1 yellow power wire.



If you have any idea why it leaned out and started acting up please chime in.



Thank you.

I just hooked up the other grey w/ yellow wire and that seemed to do it.

wired

I would have put a load reduction relay in instead of clumping every thing together , unless there is one already being used

Could have been the Air Temp sensor was unhooked, assuming cooler outside air, engine would be running too lean.

I think that grey wire had something to do with the ecu. The other grey wire lit up my coolant temp dash light when I put power to it.



Also what is a load reduction relay? That's sounds important and I put everything in an easy to work on spot.

You need to fix that mess of wiring and change to a relay based product with a fuse. That sounds like a fire waiting to happen.

Thank you for your advice. Burning down my truck is definitely the last thing I wanna do.
