Sunday my 85 Si died at a red. That ended up being the 15 amp ecu fuse. I don't know why it blew. But I popped in another and we were good.

Up until yesterday we were good all day until right after I gased up (I don't think it's related) A few miles later the car died while driving but I was able to start it back up again. A few minutes later she died again and I pulled to the side of the road. She would crank but no start. I let it sit for a while then she started right up. And the same thing happened once more before I got her home. And this morning everything was good until after a few short trips. And now she won't start at all.

I was thinking ignition control module but I just checked with an old plug and there was spark. Pump is working. Fuse is still good. On Monday fuel pressure was at 41 psi I don't know if anything has changed since then.
Tomorrow I will check everything over. But any ideas on where to start?

Main relay intermittent failure.

My B16 EF had terrible main relay issues which were almost exactly like you are describing.  They're known to go bad in older hondas and just to be intermittent.  I ended up keeping a spare on me at all times.

My relay is jumped.

My relay is bad. But it's jumped so I don't think it would be a problem?

Bad contact at the jumper?

I haven't checked yet, but the pump is coming on.

I was told this could be the ignition switch.
Is that possible if I am getting both spark and fuel when cranking?

Definitely worth checking the ignition switch.  The contacts get eroded, and you get intermittent and then permanent failure.  I had IGN1, IGN2 and the start on manual switchs on a 400,000 km prelude, and I;ve seen ignition switches fail while actually in motion.

My problem is actually my injectors aren't firing. Dead ecu? Would explain the ecu fuse that went.

[andrew.rios94]

Got it! The connector for the resistors for the injectors doesn't lock anymore so it just came loose.

Good easy solution.
