Car gave engine light when driving down very muddy road, but was fine. Then next day was driving the same road to work and the engine shut off and gave engine light again. There is no spark at all. Still getting fuel, air and cranks fine. Changed ignition coil and ckp. Checked ignition relays and main power relay they seem fine. I think it had a code that said p210. Anyone know what might be a good option to try next. Thanks
