No SPark Everything looks good and checks including ECU

[Seamus]

So my harmonic balancer broke and i replaced it. During the replacement the crank pulley DID NOT turn counter clockwise even 1 degree. Car will not start now-no spark. Every relevant sensor checks out and ECU looks good. All fuses are fine. Anyone got any idea where else to look or what to check? Thanks in advance for oyur help.

ohh a little more background, I replaced the pump and regulator with a walboro and aeromotive AFPR also today then i did the harmonic balancer, so fuel pressure shows 20 psi while cranking wiht vacuum connected. Idon't think this is an issue though, and obviously is not causing the no spark situation.

Check connectors on that side of engine could of unplugged something like your coil or ignition module while replacing HB.

Thanks for the replies guys. All that stuff checks out though. Car is a 90 GSXbtw.

Power transistor

Thats what i was thinking. Power transistor and ignition coil wires especially on a 90. Mine were brittle and the coating cracked and chipped away on most wires in the engine compartment. Doesnt take much movement for bare wire to be exposed and almost no contact for a short.

thanks guys it was the PT wire. Repaired, car fired up perfect which was a blessing because while it was down this week I upgraded the fuel system, turbo, clutch,and some other things so I was praying that the car fired making all those changes at once. Man this forum is great. I bought this all stock 90 GSX about two weeks ago or so. the car was all stock but the previous owner was an idiot and the car was a basket case that needed a lot of work. The car had a perfect rust free body and interior but under the hood was a mess. Seaching on these forums allowed me to fix every crazy problem and get this thing running in about a week. i only had to post one thread. I've been a member for a long time but rarely post, I don't understand how some of these guys cant find answers on this site and have to post all these stupid threads.
