I have a 2001 F15EHZ 4 cyc. It was running fine. Went to restart and would run only with the choke out. I pulled the plugs one was fouled. The other nice and tan clean burning. I cleaned the plugs and it does not start. I pulled the plugs again and grounded them to the block and turned the motor over no spark to either plug. The dead man switch laynard was in. Would it be the coil,and how do you test it???
