Car was running/starting before winter. LQ4 swap with bigger injectors, 2.5bar MAP sensor. When cranking the commanded AFR is crazy low (3-5:1 ratio range) and the injector pulse is 30+ msec, and keeps flooding cylinders to the point that spark plugs won't even ground and spark.
Originally when I went to start it up a couple days ago, the MAP sensor was reading maxed out (210kpa), and I discovered the black ground wire in the MAP plug on the harness wasn't connected to ajune 8 no start on tune 56.hplTune56.hpt ground.
Also, this swap has had gauge output issues from the beginning.. tach/speedo outputs from PCM never worked when connected properly to Speedhut gauges. And MIL light test "on" has never worked.
Tune and scan of cranking are posted below. I'm thinking there's some screwy internal ground in the PCM that for some reason gave up the ghost over winter, however the car was running well with this tune the last time I drove it in October.
Thanks for any help/insight guys..
