MS3x Braineak '03 Miata Crank No Start
3 Attachment(s)
I have a '03 Miata that isn't starting. It cranks and i can smell fuel but no start. I am currently running no o2 as the narrowband sensor isn't hooked up. I have a lc-1 that I will get either tomorrow or monday.
I pulled a plugged and I didn't see the spark plugs sparking. The crank angle sensor is gapped to 0.040. I've never logged data before so i'm hoping what I uploaded for you guys to view is correctly done. EDIT: After many attempts, it started ONCE but then died the moment i let off the gas...Now i'm back to it never starting again. Just cranks. I do see rpm in tuner studio (about 180rpm) during cranking. Post#3 has newer info. |
How can you have any pudding if you don't eat your meat?
How can you crank an engine on a megasquirt if you don't have an oxygen sensor? Hook up all the proper parts and then worry about trying to crank it. |

Bump, did more testing and figured out i'm running lean when I crank. AFR is at 17, not sure if this is normal for cranking (I know that 14.7 is ideal for idle/cruising).

Usually you are slightly rich for cranking

Try bumping up your req_fuel value and/or adjusting idle ve.
I had a similar problem with my ms3x. |
