So... I did what was highly recommended to me. I redid some main grounds (main engine ground, fuel injector ground, & grounded both coils). I used to get absolutely no spark from my leading coils, but they were reading at a resistance of 0.6 ohms, so they seemed to be good. After doing all this, I finally started getting some spark, but what is strange is when turn over the engine, I get 3 quick sparks from the leading coils and after that, it's nothing. What's happening? Is there anything anyone thinks I could try to solve this? Is there any other way to test if your coils are good (even the igniter as well)?

 

When coils or ignitors go bad, it's either they are working or they are not.
It's very rare to see intermittent problems like you described.

Try and do an ECU error codes scan?

Okay. Would it be smart to also do a better ground for my ECU?
