Main Relay Problems...
I already searched a hundred threads but none had my symptoms...I just picked up another relay and plugged it in and now instead of clicking really fast like my old one, this one makes a quick static type sound when I turn the power on...WTF is going on???????
i had the same problem like you its a quick fix...your battery is not giving enough charge to you starter to start your car..i took my battery to o'reillys had it checked and the battery had not charge to it..
Ok got the relay to work normally, fuel pump primes and everything without any strange noises...but now the check engine light does not click off. Oh yea do the two black wires that go into the relay grounded? Or do they carry power?
i had a problem with my main relay wiring...it works fine...but i had a CEL for some reason.....no idea...+ it was reading 10? or 1 or 0...and i dono why everything was wired...

Yes, the PGM-FI main relay is connected with the black wires coming out of the ECM, going through the main wire harness, into the engine compartment wire harness, then terminating at the main engine wire harness.
ECT, VSS, O2, ECM, and the main relay are connected together, via the harness, to the same ground.

Dude, your car has soo many ******* problems, it's not even funny. You don't even drive the damn thing. See, stock is better. No problems here.

As far as the problem goes, unless there is voltage being enduced into a ground wire, there shouldn't be any voltage there. Voltage gets enduced into a ground wire, only for a fraction of a second until something trips (in this case, a fuse). But you have constant voltage there, which I don't udnerstand. Unless, something was done to the relay, internally.
What color wires are coming to and from the relay, be detailed.

this is for a 92-95 civic, so the colors should be the same for a DelSol. But I'm not positive.
