2003 TB (200K) some times won't start cold or hot but switch relay with others and it works, sometimes these relays have been used for the fuel pump and it works
Thoughts, comments, concerns?
Thanks all

How does the wiring look?

Could the bad wiring cause other minor issues like the power window control, drivers door, and interior lights not working. These are minor inconveniences because a good jolt will get the window control working.
Any way will look at this on Saturday and report my findings thanks again

If your having fuel pump issues It would be more of a stall issues, which is what I was experiencing. They have since not occurred since I installed a new unit. I'm at under 100k miles but I'm learning that key parts like fuel pumps need to be changed out if any issues occur with the fuel systems
