90 accord ex no fuel,or spark
 

fininishing up on a burnt valve and a damaged piston on #2 cylinder. Now no fuel and spark. Wondering why because it was running before work was done. Computer only blinks once,when keyed. "check engine" light does not come on when trying to start. Could get "check engine" light to activate only by pulling "ecm" fuse on "on'. Left fuel line at rail disconected to see if fuel pump runs. Checked all fuses are ok. Engine turns over nice . Can't pull any codes. I know FI honda 's do have bad main relays go out alot, gonna try a boneyard one soon. But if anyones got a tip to help me out please let me know ..I'm thinking there could be a special procedure to follow to get fuel and spark going. Thanks for any responce.

i think it's the efi too, or you might have forgotten to hook up some wires.

also the efi relay can be fixed just need to pull it out and take it's cover off, then you will have to solder 2-3 pins and it will be as good as new:yes:

Yes I did leave the black double ground wire located off the thermostat housing thanks Hondaman. Runs good. Smoked for a hour though. Cause residue oil that was in exhaust was burning off. Bye the way,when checking codes I just cut off connector wires and tied them together and a code 4-3 was going contiunliesly while I had it running at 4500 rpm's then it stopped whats a code 4-3.?

fuel suply system.
