injectors not firing both sides 12v
Im really starting to hate this i should have just bought the ms new an built it myself. heres the problem i got spark to my leading coil. i was told the trailing doesnt start to sparkk till 800 on ms1. So i tryed firing the car an nothing but sprak no fuel.
Pulled my uim off an checked the power to the injectors with the key on. Both sides of the plug had 12v. no negitve. but heres the thing i turned the key on to power the ms with my dad outside touching the injectors the lights are dim an then they get bright an the injector clicks once. is this normal. Also how can i fix this i have everything set to aarons settings on programing ms1. the board i looked threw an everything is good as to what i had to do to run rx7. no burned out stuff nice n clean. so can anyone help me i have my injector 1 ran to pin 32 33 injector 2 34 35 on the db37 n i have the power ran off a 12v switch for the ecu

It's normal for the injectors to click once before cranking.
Assuming you have RPM and spark you should be getting fuel injected unless for some reason you're triggering the flood clear mode (should be an indicator at the bottom of the megatune screen that shows that).

To be honest, it is also very difficult to figure out what you are asking because of your writing style. I've been reading this topic since the 3rd and I can't figure out what tests you are running and what you are hoping to see.
Can you perhaps list your issues in a point form format?

ok i got it all good an firing all the stuff i need. the car fires but i have to stay on the gas to keep it alive. It start popping back firing like my timing is off. I checked my wiring i think my cas is wired correct. IS this correct
Board green 2.2v
G+ x14/pin 31
NE+ pin 24 on the db37
?G- pin 31
?NE- pin 7
igt-L pin 25
igs-t pin 27
igt-t pin 29
i also have pin 14 grounded. Does the negitive of the NE an G sensors matter were they are on the pin out can i just ground them to the Megasquit or are there specific pins.
