I have a 96 honda accord ex which had a blown engine. I swapped over another engine and was able to get it to run twice, but since then, it just cranks over and feels like it wants to start up but then dies again. I'm getting spark, timing isn't an issue. I'm getting fuel to the fuel rail but it seems as though the injectors are not injecting fuel into the cylinders. Someone told me that it may be the fuel injector relay on the passenger side of the car, on the firewall underneath the fuse box. Would this be the culprit to why I'm not getting fuel to the engine? I know the vehicle runs because it did run, twice. Would anyone know what the problem is, and how to fix it?

Bravo

I'm having the same problem but I've tested a few more things than you (possibly). Have you tested the main relay yet? That sounds like it could be right up the main relays alley. I used an online manual to test mine, do you have a manual? It'll tell you which terminals to check, which ones to ground out, etc.
