Integra: Integra 97 gsr won't start, has spark, fuel pump working

Customer Question

Integra 97 gsr won't start, has spark, fuel pump working roughly 55 psi, I checked the main relay with another running integra still won't start. Sometimes it turns on sometimes it doesnt. It's turning over strong changed the distributor, but not the cap since its MSD. I am running out of things to check. Is there something else?

Hi there.Does it start on starting fluid?
Customer: replied 7 months ago.
I was going to try that but I don't have any available at the moment do you think it may be injectors? I have heard of people testing injectors a poor mans way. Is there anything else I could try
Expert:  Juan Crespo replied 7 months ago.
It could be the onboard computer not providing injector pulse. Do you have access to a scan tool that can read engine/sensor data? Voltmeter that can measure DC frequency? Scope?

Damn, I do not and it has an odb2 to odb1 conversion harness. My Ecu is tuned turbo 310 injectors, walboro pump. If I get a voltmeter should I be measuring current via injector harness clips? What should it be reading? I am guess buying starting fluid bypasses the need for a voltmeter. But why would it run great sometimes and won't start at all other times?
Expert:  Juan Crespo replied 7 months ago.
Intermittent operation is usually caused by poor connections. Without the tools I indicated on my previous post, there would be no way of knowing what's going on with the system.At this point, i don't think I'll be able to help you. I'll opt out to let others try. Please do not respond until another expert responds or the site will cycle your question back to me.
