Starts up but dies right away
Hello everyone,
I have a 92' Miata with a 90' Miata 1.6L Boosted with Megasquirt PNP 2.
I was driving back home from work a month ago then I started getting misfires and my car even shut off but I got it back up and running again and barely made it home. I knew it was my spark plugs that were going bad so I replaced them all and ran like normal again then I did my ignition timing on Tunerstudio got it lined up at 10 degrees and this is where all the problems started happening.
I believe after 1 or 2 days, I tried starting the car up but it would start up then die right away and I looked on the forums and did everything everyone suggested but no luck.
I replaced
-spark plugs
-spark wires
-fuel filter
-coil pack
-CAS angle sensor
-cleaned throttle body
-cleaned idle air control valve
-I checked the grounds below brake booster and pretty much everywhere else and cleaned it and sanded the frame
-cleaned the pins to the CAS angle sensor
-checked vacuum lines but seems to be no indication of any leaks
-checked boost leaks
-fuel pump works
I can't think of anything else to do so if ya'll have any suggestions that would be awesome.
I also did mess with WUE ENRICHMENT and AFTERSTART as well no luck.
I noticed however, I bumped the fuel table values around where I usually idle way up and it started and idled for awhile but then stalled. The values are really high that would make the Miata run SUPER RICH.
Almost forgot but as soon as I try to give it gas, the car would die in an instant.
I'm also running IAT and already checked timing ignition timing again after replacing CAS angle sensor and everything was lined up perfect.
I've been stumped on this car for over a month now and hoping someone can lead me the right direction
