... this misinformation:

"... what finally was the problem was the base of the ign coil was not sending the signal to open the injectors."

I believe some so-called "mechanic" told you that, but it is total BS. There is absolutely no connection between the ign coil ("base" or otherwise) and the injectors. This bogus tip could send readers off on a wild goose chase. It sounds like a screwed up version of what can actually can happen...

If the ignition Control Unit fails to send timing pulses to the Fuel Injection CU, the injectors won't open because the whole FI system is dead without those pulses.

If the Ignition "Amplifier" (in the coil "base") fails, there will be no spark. But since the Ignition CU has no way to know about it, its timing pulses still go to the FI ECU, allowing the Fuel system to run.
The result is no spark - no start - and wet plugs.
