Trying to get started the RIGHT way
#21
Update: i change the igniter and put in new plug ngk bkr6e-gp and the car started
Then i put back the megasquirt with the original tune. I ajusted the req fuel for my 440cc the car running good except i aleays need to keep my foot on the throttle a little bit or i hear a relay click and the car just stop even if im at 3k rpm once i remove my feat on the throttle i hear that click an the car just stop

Is your MS built with the high side current driver outputting to 1C on the harness?
You need to understand that it requires a certain amount of silliness to get the fuel pump running on a 1.6L with MS. I can't remember if Blaen's unit had these nessecary steps taken on his or not.
Pull the ST-SIGN fuse is only useful if the unit has the high side driver cirucit built inside to run the fuel pump through 1C.
Otherwise, it may have been built to send a ground to 2O on the AFM connector and needs to be jumped to ground.
remember, you have a custom built MS unit, this is why you needed to maintain the custom tune loaded into the unit, just as the harness and wiring may not be built to any sort of standard. So these are important questions to ask you.

Brainy....Braaiinnnyyy.....Listen to his symptoms, not his theorized reasons why something is wrong!
Steven: You aren't controlling the IACV and are trying to idle with insufficient air - either you need to get the IACV working, or you need to increase how much air bypasses the throttle body via the idle mixture screw.
Fuel pump doesn't have a goddamn thing to do with why your engine isn't getting enough air, and the fuel pump stuff is perfectly fine if you removed ST_SIG

Hears a click, motor stops running, suggests to me the fuel realy is getting tripped off somehow.
I only wired maybe 2-3 units with the high side driver, I wasn't sure if yours was one when I fixed your harness.
Otherwise I wire the fuel pump through the AFM connector and it requires a jumper wire in order to work.
But, I was assuming the AFM was still acutally in place and allowing the fuel pump to run, and I was eventually, in a very long and drawn out way, going to get to lack of airflow causing it to close the flapper and the fuel pump shutting off.
i have method to my annoyance.

idle control algorithm is set to NONE, is that supposed to be like that??

Dude! I love you (dont take my words to serious ahhaha)
Guys seriously i searched , searched, read, re-read. Maybe i wasnt looking at the right place! I unplugged the tps and tada!! it worked!! I thank you so much to all you guys for your help!
