2002 start then doesnt. 45000 miles, auto. Did fuel filter, then went to mechanic and got 1 COP based on scan. Started again so replace relay and fire right back up. Now everyone other day it takes multiple tries an hour apart to fire up.

The COP definitely made a difference.

Is there ecu type thing? Grounding issue?

Thanks, this seems different than the last issue where cop was replaced, it ran rough before that. Was trying to say all what was done to it in the last month. But i guess could be a drip and another cop or the same 1 again.

I appreciate the help!

Could it be a fuse and not the relay?
