Question for the sr gurus out there, zenki s14 sr in an s13 chassis cranks perfect but won't start. Pulled the cas(lined up with the marks on the housing at tdc on compression stroke beforehand) and rotated it by hand and I hear all 4 coils firing with every one full rotation but only 2 injectors pulse for every one rotation. Also no injectors will fire unless I spin it pretty quick. Bad CAS or am I chasing another problem?

Opened up the CAS, and the trigger wheel inside was slightly bent and in one spot touched at the bottom of the receiver in the CAS. Carefully straightened that out and it seemed slightly better.

New swap, factory internals, 160-170psi on all 4 cylinders, ecu, 370s, supra tt fuel pump, tomei fpr, factory maf, ngk bkr6e, wiring specialties engine & trans harness.
