The ground bolted the the thermostat housing.

 

oh shit i dont have a ground 2 it could that be my problem?

 

the fuel pump has its own ground so i doubt it. assuming ur battery is grounded to the chassis good then thats not the problem.

its the relay....... did u actually test it or u just saying its good. u have to make a jumper wire and check it manually to make sure it clicks on, its actally 2 relays combined into 1.

so the ignition part of the relay could still work while the part that turns the pump on is shot to hell.

 

OF COURSE that would be your problem! The main relay is the switch for the fuel pump. the pump could be perfectly grounded and still wont kick on because the relay wont without a proper ground.

 

as long as the chassis is grounded with the battery the relay will work. the thermo ground one dont matter for that.

relay is easy enough to test but i doubt he knows how he didnt even know how to check for codes

 

Without my thermostat ground attached my main relay chattered and buzzed...and wouldnt kick on. Just saying.

 

^Definetly correct
The ground that the ECU supplies to the second relay isn't anywhere near the ECU. It is in fact way up front on the engine! There are several wires originating from the ECU that are grounded on the engine block (probably so there won't be problems with bad engine to bodywork ground straps). On the CRX these wires are attached near the thermostat housing. Other models may differ. If the connection of these wires to ground is loose or corroded, you can get symptoms similar to a bad main relay.

 

damn so that's probably what I have to check for too?? Cause I tried another main relay and it still wouldn't activate the fuel pump....

 

lol now my fuel pump wont work........... it worked a few times now nothing. jumped it to the battery works fine, checked relay works, just incase tried 2 other relays i have.

jumped the wires on the relay to turn the fuel pump, turns on. but wont turn on with the key. god damn hondas

im tryin to get my fuckin swap running and then this shit happens
