Used etec one and changed fittings can hear pump run and prime. Once I start with starting fluid will run all day and start back if it isn't off too long. Im thinking its start assist circuit but dont how to check that.
Will only start on starting fluid and runs rest of day and rarely the next day. If it sits longer than that no Bueno. New fuel pump, all relays, starter and 2 new batteries im driving myself crazy with this one.
