Well...this may sound simple, but it really is true. All an engine needs to run is spark, fuel, compression. Pull a sparkplug out and see if it is firing when resting on the block. If it is, then check timing and/or see if it's 'flooding' with gas. If it is ok, then you should at least be getting some backfire or misfire. Try some starting fluid, it has a better 'flash' rate than gas. Oh.. and make sure that the coil is actually putting out enough of a 'pulse'. If the sparkplugs 'spark', they should have a blueish hue to them and be quite bright. If the coil is weak, it will look orangeish or yellow. It _will_ make a difference, so don't be fooled by the fact that it has a spark, it must be a strong spark. Let us know how it goes, Cheers, Brandon Thomas '88 C900t16v SPG
