punkypete - I don't know if you have found anything out yet, but I had been having somewhat of an issue starting my '04 daytona. I went through the plugs, plug coils, gas fittings, checked the injectors for resistance and the injector wires for resistance. I also checked the tip over sensor, crank & cam position sensors, all the relays, the starter, and had even taken mine to a "mechanic" shop who told me that I had seriously low compression (60/80/60, in the cylinders respectively). Turns out, I have a messed up battery. I have had my 'cycle torn apart for the better part of four months trying to figure out the issue, and it was a battery (which I had bought new and even had tested to ensure that it was holding charge before I put it in the daytona!) - Not to mention the "mechanics" I had taken it to, after doing the compression test, was trying to convince me that I needed a top end rebuild - all b/c of a stupid battery! The moral of the story, go get yourself a battery charger that has a microprocessor which can check your battery's voltage and your alternator's voltage as well as charge your battery (I bought a sears die hard charger for about $70 new - here in the states) and it worked like a charm! Also, for the future, I wouldn't use starting fluid any more. That stuff can really burn up your valves if your not careful. Just get yourself a plastic spray bottle and pour some gasoline into it and do the same thing - gasoline engines aren't designed to burn ether. That stuff is used mainly for diesel engines that won't start during cold weather.ok,1stly,fanx to every1 who has helped so far,daytona still wont start,just got a dealertool diagnostic kit,plugged it in an it reads that there isnt any fault with anything,no faults found,still wont start,any ideas out there?
