hdi wont start!

Sounds like a worn-out battery to me, that or she's struggling for fuel pressure. Towing it ten miles with the hazards on shouldn't flat it, not by a long shot. Do you have access to a battery tester?

If you can get it to someone with diagnostics that would be ideal, see if you can find anything out of normal parameters - fuel pressure at cranking should be ~280bar.

i got a lad with diagnostics and it came up crankshaft/cam shaft sensor. so i got a new crankshaft sensor and it didn't fix it so have been looking around for broken wires. even tried easy start and that didn't work! we checked the timing and that was all fine, it goes to fire but then stops and i turn it over and the speedo goes to 120mph for some reason
