busabuggy

Hello everyone, just bought a buggy with a Busa motor. cylinder 4 not firing. narrowed it down to possible low fuel pressure. checking pressure later this morning. my service manual is on order, can anyone tell me the normal pressure I should have @ my injectors?
Did you ever get this sorted out? I believe the manual says 43 psi, but I’ve been told between 43-50 psi. I’m having a similar issue and wondering if it is also fuel pressure related. Running rough and a lot of bogging down. I narrowed it down to the #4 cylinder by unplugging each coil while running and #4 showed no change when unplugged. All the coils test good and the CKP sensor and stator test good. I think it has to be fuel related.
