I was driving, and all of a sudden the engine started bogging really bad. I was just taking off with a bit of gusto, so I figured I must have put in 4th instead of 2nd (I didn't), and tried putting it back in. The tach moved, so it was still getting a bit of fuel at that point, but immediatly after that, nothing. I coasted into a parking lot, Tried to crank the engine... nothing. Turned it off, turned it back on, nothing, and I noticed the main relay wasn't clicking over. Swapped the ECU for my spare one... nothing, and main relay still not clicking over. Opened the service port on the fuel rail, turned the ignition to on, no fuel came out. Whatever the problem is, it has to do with the main relay, but this one is brand new, so I'm thinking it's indirect, something else not telling the main relay to click over. Where should I look for this something else?
