i don't know what kind of "electric gun" you are using. i have the new snap on half inch electric and it gets mine off most of the time and I have used the breaker bar and bump the starter but the best way is to use air impact or get a chain wrench and a big breaker bar. All the V8 TIMING BELTS WHERE YOU CAN'T GET A IMPACT IN WITHOUT PULLING RAD OR CONDENSOR i ALWAYS USE BREAKER BAR AND CHAIN WRENCH NO PROBLEM
I assume you put the pulley back on to put in the chain wrench, right. I might need to try this technique.
Please note that if you do this, you may damage the harmonic dampner.
The outer ring is bonded to the inner hub, and applying that much force to the outer ring may partially shear the bond. If you do use this technique be sure to put all the stress directly in the rotational plane of the dampner. Any side load will dramatically increase the chances of shearing the bond.
Nothing good ever comes from a harmonic dampner seperating at 7ooo revs, so I usually avoid doing anything that may compromise the unit during a t-belt service.
I posted the breaker bar technique quite awhile ago. While not *exactly* OSHA approved, many techs have used this technique with great success for years.
I like to set the motor up just after tdc when doing this to give maximum valvetrain clearance, but it probably doesn't matter much... /ubbthreads/images/graemlins/dunno.gif
As Turbowop points out, make sure you have a good bite on the crank bolt, and then lay the bar against something solid and then just *bump* the starter.
It'll break it free, everytime. /ubbthreads/images/graemlins/smile.gif
