now that I installed a walbro 255 my fuel pump doesnt come on all the time, does this pump put more stress on the main relay?

I had main relay problems when my car was stock and it was hot outside, so i should replace it anyways, but has anyone had this problem?

I had the same situation , stock pump, when it was hot my fuel pump would not prime. so I put a new main relay in, no fix, put a new walbro 255lph pump in ,no fix. eventually it would not prime hot or cold. checked for voltage coming out of the ecu and thats what it was, the ecu was slowly crapping out on me. not trying to scare you but it sounds like my situation dude.

maybe the ground on the thermostat housing is bunk

where is the ground on the thermostat housing?

plus it is the main relay, becuase on the 92 civic it was always a problem, there was not enough room in the relay to dissipate heat and they became heat soaked
