Since our 1st post on 12/28/06, my husband and friend have checked most everything that was received thru replies. Apparently there is no longer a fuel problem, now it's a starting problem. It will only start if you put gas into air horn. Igniition problem eliminated. Pulled off electrical fuel injectors. Put a 9 volt battery to injectors. Fuel is fine. Plenty of fuel both sides. Hooked electrical back up -- no fuel, no spark, no nothing. We assume that fuel delivery system is fine. Problem lies somewhere in electrical system that tells injectors what to do. Also changed TBS, it doesn't work. Any additional replies are most appreciated.
