Cranks but wont start - spark issue?

[a4andy]

Alright, I need some help for my GFs car!

When she first got it, it was all fine, then after a few days, the car wouldn't start. It would just crank and crank. And when it did start, the first few seconds the car sounded like it was gulping for gas or gas and would shake.

When I was troubleshooting the issue, I was able to hear the fuel pumps prime, there was gas in the tank, so I checked the sparks. All but one gave an orange spark, so I decided to change all 4 of them.

That worked great for a week, car was running fine and all, but now it went back to the same problem. I checked all spark plugs again and they are all orange/weak once again (these were brand new a week ago). Anyone know what's going on? I am about to get another set of spark plugs to see if it works agin, but even if it does, I have a feeling the same thing will happen in another week.

Car is an 03 Civic LX Coupe

Orange spark means weak ignition, could be coils. How many miles on the car?

[a4andy]

Car has 135xxx
I just replaced the plugs once again as a temp fix, made sure to test the spark and they all gave a white light just like last time. Car also started.

But I still think the same thing will happen within a few days.

Could it really be the coils even though it isn't giving a weak spark on new plugs?

All fuses seem okay, where exactly is that ground at?

Car has only been driven about 4 times and it seems to be having the old symptoms again. Tested the sparks and they are now turning weak, not white like when I first tested them brand new...

Any help on what it could be....?

What about swapping the coils around? See if the problem follows the coil?

O'reilly's gave us NGK Platinums (ZFR6FGP 7100)

No CEL codes, I have one of those bluetooth scanners and my phone isn't giving any faults.

I did that too, all plugs seem to be going weak together, it isn't just 1 spark plug that is doing it.

Is that even possible?
