make sure your cap and rotor timing is correct double check spark plug routes (mistakes happen). maybe your timing is off in general.

This is kind of a long shot but if it is difficult to start after sitting all night but then starts just fine during the rest of the day then you may be just a pound or two low on fuel pressure. This engine needs a minimum of 60 psi of fuel to start properly. If you have only 59 psi it will crank and crank and finally start but will behave all day long as if nothing was ever wrong. You could also have a leaky fuel regulator or injector that is causing it to be partially flooded when you attempt to start it but usually those problems bothers more after the engine is warmed up. Even some new fuel pumps won't put out the needed 60+ psi and sometimes the fuel pressure regulator can go bad and not allow the pressure to build up to the 60+ psi range. The only true way to know for certain what the actual pressure is to have someone test it with a very accurate test gauge. Hope this helps out a bit and good luck.

hi there
If you have fuel pressure the next thing you need to check is if you have spark if there is no spark it will not start hope this helps you thank you and have a great day
