I have a 1989 gtu na fc that will not start. I am thinking it is a vac leak but I know for sure it is not injectors or fuel related, not AFM related and the only code I am getting is for fuel pump resistor relay which I removed and bypassed. It starts and revs to like 2k and dies. If I push in the AFM it revs higher but will not idle still. I got a new AFM as i thought that was the issue but the new one does the same. Might be CAS if I have set it wrong but it does start so idk. Any advice will help. Thanks lads
