SR swap running issue-you'll have to be pretty smart for this one.....

Blacktop SR20DET with 5spd into 89 coupe (auto to man conversion done).
Car will barely start, then runs on two cylinders(the middle two only). I unplug the MAF and it makes no difference, BUT, the RPM's WILL raise over 2500 rpm no problem.

I have:
- replaced MAF with known good one--no change
- replaced ECU with known good one--no change
- replaced CAS with known good one--no change
- chkd' continuity between sensor plugs and blue ECU plug--all seem good
- replaced wire harness with known good one--NO change!
- pulled valve cover and put CAS 180* off--would not start

I have pulled each coil pack one at a time and checked:
-spark across gap--all fire
-constant 12v to top of coils--all good
-ground--all good
-signal--something measured as it fired
-all gapped at 0.032

All grounds are attached in approprite places

I am at a total loss. Please help.

Thanks in advance
