Have a 1990 accord of my mother-in-law's that has fuel pressure up past the fuel filter but for some reason it never makes it into the head. It is a 4 cylinder with programmed fuel injection. If I prime it through a vacuum hose it runs until the prime runs out. I put another ecm out of a junk yard in it because the other one had been wet and was stuck with cel 14 and wouldn't reset or transition with new trouble codes as i was under the hood unplugging stuff. Now the new one does register new cel's, but I don't think any fuel is actually being injected. I haven't troubleshooted the injectors because I'm sure they didn't all go bad at once (not to mention I'm by myself and don't have anyone to turn engine over while I check) and btw the fuel pump does run consistentantly like it should. I bought a chilton and what a piece of crap. It tells how to remove components but no troubleshooting at all. No chronological sequence of fuel being delivered into the motor so you can see how it's delivered and what controls this sequence (ecm?) of events and how it knows how to react.
I did clean the idle control valve but I don't think that would keep it from starting at all. It probably just would idle right. Thank you in advance for any help you can give me. Also have fuel pressure at fuel pressure regulator but I didn't have a good enough connection so it would leak out of my cobbled together pressure checker pretty fast but I did have presskure (30 or 40 I think) so I don't know if it really holds pressure like I assume it should, but once again, it won't start or even hit at all unless I prime it.
Please any diagrams, schematics, flow charts, or even if you want to talk about my mama, would be greatly appreciated.

 

It's possible the fuel pump is leaking down. Or could be a fuel pressure regulator.
