my wrx is finally together with a built short block. it started once but now it wont crank again.. the obd2 port dosnt work when the key is in the one position. The temp on the dash is maxed out hot. I check all the grounds with a multimeter. My car also has tgv delete and secondary air injection pump delete. Sometimes will will randomly work.. also I cant here the fule pump when it dosnt crank.
Thank you

There are multiple. To be honest i don't have the fsm handy and am not exactly the best with electric diagrams. Are you getting consistent power when you turn the key to accessory and not start it?

Intermittent cranking leads me to a few things to check. Ground connection is number one. Also a possibility is a security system issue, or aftermarket remote start. Some security systems will cut power to the fuel pump.

You could also have an issue with the wiring in the steering column.
