Hello, my name is ***** ***** I will be glad to assist. Please allow me a moment to gather some information.

Expert:  Roy Belding replied 13 days ago.

ok, from your description, it sounds like you may have a fuel pump that does not work at times. I would try checking the connection at the pump to be sure there is no damaged pins or corrosion.

I would also check the pressure even though it runs now. if you do not have a tester you can rent one at a parts store.

Expert:  Roy Belding replied 13 days ago.

possible but would have more issues. also, it would code since it is a fuel control component.
