I hired a mechanically inclined friend of mine to install the new fuel filter and accumulator in my home garage. Before I got home, he had removed the old filter and accumulator as well as the CDI. After installing the new filter and accumulator, we attempted to start the engine and got crank but no start. We then also lifted the air flow sensor during this process. My friend and I then observed that there was a blown fuse leading to the CDI. My friend then confessed that he accidentally caused a spark before removing the CDI, which ultimately led him to disconnect the battery. In sum we were obviously cranking the engine with no spark, which led to the fuel flooding. Fuel was in dripping from the exhaust. Quite an event.
A different friend has now assisted in removing the spark plugs and installing the new fuse and confirmed spark.
What to do now?
Thanks for your help.

Thunderroad,
We all make mistakes and learn from this experience. Nothing to be ashamed off. Sometimes, sharing this unfortunate bad experiences help others to be aware of the problem/s lurking ahead of us.
If you have a CIS pressure gauge install it and measure your cold control and system fuel pressures without running the engine. Just the fuel pump and your system will be primed and ready for start up. There is no need to use starting fluid because you are dealing with a fuel injection system particularly a CIS. There is sufficient fuel delivered by the 7 fuel injectors during a cold start. And this is one of the basic tests you have to perform before attempting to start the engine during troubleshooting.
Make sure you have a fully charged battery and able to crank the engine fast and strong. Three (3) important things to check and verify:
a). Ignition (spark, timing, etc.).
b). Sufficient fuel pressure for the injectors to form a uniform spray patterns.
c). Absence of significant air leak in the system.
You should have no problem getting a CIS motor to start and run. Your success in dealing with CIS is all about preparation and verifications of conditions. Keep us posted.
