Car: 95 civic w/ built gsr swap less than 5k on motor

Problem: Car wanted to overheat while sitting in traffic. Checked fan and it was on, and with less than 5000 miles im sure the water pump is still good. Changed thermostat and filled and burped system. Car ran fine sitting in driveway for 20 minutes or so with no overheating. I later went out to the car to start it and it starts and immediately dies. I give it gas and it starts again and stays running while i nurse the gas pedal. When I let off the gas it dies again. I try to start it again and it will not start. When turning key to ignition position the main relay clicks constantly and the check engine light is dimly lit and flickering to the sound of the main relay and the fuel pump will not cut on. I tested the main relay and it works fine outside the car. The light on the hondata is on as well but blinks slowly. I also checked all plugs and connectors underhood and all appear good. Anyone have any ideas what could be wrong?

Sounds like it could be the ground on the thermostat

 

I checked that. Its good and tight and theres no corrossion. The fuel pump and injectors are not getting power. The main relay is clicking when it is in the car but outside of the car it tests fine. I had an ecu go bad before that caused the same problem so I swapped ecus and its still a no go. Thanks for the response though.

 

well i know i said i checked it and that there was no corrossion and it was good and tight but that was what the problem was. i ended up running a ground from where the thermostat was directly to the battery and it started fine.

 

you over heated it do a leak down test

 

it soundslike a power supply issue.check all the connections

 

If you over heated it, might be a head gasket or warped head. Honda's (or anything with an aluminum head) are bad about that. Do a block test.
