Used 07 Road Glide 30K milesRinehart out, stage 1 in, race tuner, battery less than 1 yo, no codes or CEL, fuel pump and light come on then a few seconds later turn off consistently. Daily driver starts/runs fine going to work and at end of day going home, cold start. Recently after good warm up ride 20- 30 minutes short quick stop and go for gas, groceries etc. Bike won't run. Cranks ok, cycle main and ignition switch no joy. Try several times over 15 minute period and cranks fine just won't fire. Wait 2-3 hours it cools down and runs ok.
I can repeat problem and here is some of the things I tried. Used a multi meter that has an amp clamp and put it around the spark plug wire. Running it reads 27 hz, when it's hot and cranking it reads 20 to 27 hz but won't run also the tach is showing rpm. Also sprayed a little starting fluid and the bike ran for the few seconds but would not run on it's own. I'm assuming spark is ok at this point.
Removed air cleaner, cleaned and inspected IAC, it moves with switching ign. on and off both cold(when bike starts ok) and hot when problem occurs. Looking in intake and revving throttle I can see fuel vapor. While trying it during no start I don't see fuel but the engine is not turning over as fast as it is during normal revving. I'm assuming no fuel.
So, leaning toward fuel side for problem. Could injectors not be working electrically and not throw a code? Could injectors or any part of fuel system not flow fuel when hot? How can I test injectors pulse width, or duty cycle electrics both when it's running and when the problem happens? How can I check injectors mechanically of they are working? Looking into getting fuel pressure test gage but it does make noise whether hot or cold, don't think that's an issue. Is there anyway of checking ECM for ignition/injector signals that I can compare when running ok and when it fails hot?
Any suggestions, comments greatly appreciated and I hope I didn't put you to sleep after rereading this long winded story.
Thanks in advance
