How do I know if my flasher relay is bad?

Symptom of a bad or failing turn signal / hazard flasher is hazards or turn signal lights that do not function. If the flasher breaks or has any internal issues it can cause the lights to malfunction, or not respond at all when the turn signal lever or hazard light button are pressed.

check fuses and relays try starting car with a boost if turns over and starts have battery and alternator checked --if clicks check starter and wiring --if nothing check fusable link/master fuse ,key not worn or damaged terminals and connections

fuel pressure regulators are normally located in the fuel manifold. They are either vacuum controlled or electronic controlled to maintain the right fuel pressure for engine requirements and to shut off the fuel pump when the ignition is turned off
If your manually adjusted unit will not do all that then you are asking for fault codes to appear and all sorts of problems to occur
