Default fuel problem works then dont HELP !!!!

yes , i have a 93 delsol with a b18c in it

my problem is that some times when i go to get in my car for the frist time for the day it wont start turns over but no fuel ive narrowed it down to its not the fuel pump and not a relay no short or grounding going on

the fuel pump just wont prime if i sit there and try turning the car off and to the on postion over and over again it will prime but wont work all the time

it happens the most when its hot outside and when i go from my house to the gas station put gas in or just getting somethin from there it wont start after

i had the same problem with my 90 crx i had but i would play with the relay under the dash and it would start

The ignition switch may be bad.

Do you also lack spark? If so, check the important ground wire on the thermostat housing.

its going bad or grounds are all corroded, loosen your grounds and clean them up.

just had a problem like that in my 92 eg hatch. one day it wouldnt start then it finally did i noticed the fuel pump wasnt priming until the last time before it started. then about 3 days later it completly died. i replaced the main relay and the fuel pump has been working good since.

stock motor? do you have an adjustable fpr? check for any leaks on the fuel rail and the injectors.
