My car wont start up after it is driven around for a while and sometimes it won't start up at all. I'm not sure what could be wrong.

Hi Sleeping Forest,

When it did not start, did you check if the Check Engine Light goes off after 2 seconds when ignition is turned to ON?

When it does not start and the CEL does not go off, it could either be a faulty PGM-FI main relay or a faulty ECM. Remove the PGM-FI main relay and check the circuit board for cracked solders. If any fould, resolder them and retest.
