280 GE motor reinstalled - won't start
 

I pulled motor from my 280 GE and did basic overhaul but now can't get it to fire up. I have spark, fuel pump kicking in. I'm sure it's something stupid I've overlooked. I still need to figure out a few vacuum lines under the intake but the engine should still fire without them. Any suggestions on where to look next would be great.

Thanks,
tony

We need more information. If you try over in tech help there will be more of a response. Information needed would include, model year and what exactly was done to the engine. A large vacuum leak would cause a no run issue. Check the basics again. Spark does not always equal sufficient energy to start combustion.
