Default Starting issues HELP

Okay...

Symptoms...

-Car would start and immediatley turn off after I did something (don't know what, I think I hit the brake pedal)
-Afterwards, it wouldn't even crank over
-Then when it decided to work it would start.

Car ran for like two minutes, then I would turn it on and off and it was fine, so I thought it was just a weird fluke. No, maybe about an hour after it stopped being stupid, again...

-This time it would crank over but not start combustion
-I can't hear the fuel pump when key is on position jump the fuel pump through the engine bay diagnostic port (b+ and fp)
-fuel pump works fine, so I'm getting fuel at this point
-I check for spark and NOTHING.
-This is where I stand stumped...

At this point I'm out of ideas. The ecu has power. I also check for engine codes (te1 and e1), not throwing any codes.

I have a multimeter and I think it's crap due to giving me stupid readings and continuity not working, so I'm not trusting it, since I was trying to check the coils resistance, ignitor, maf, etc...

ALSO, this isn't the first time it's happened. This has happend about 2 or 3 more times BUT the car would start after a couple of minutes of randomly trying to diagnose it. It never made any sense.

So I'm confused and desperate since I need to use my car.

Right now I'm thinking maybe cam or crank angle sensors or ignitor. I really don't know at this point.

NEW SYMPTOM

The car ****ING STARTED!!! I didn't do anything different. However, this is what's currently going on...

-It'll turn on and it would die on it's on idle or revving
-I can keep it alive BARELY from stepping on the gas
-The car is missfiring like a ***** when it WANTS too, which is most of the time.
-OCCASSIONALY the idle is perfect and revs perfect, but then a misfire here and there

I don't know what the hell is going on...

ONLY thing I've done is change the spark plugs and that was 3 days ago. The car from factory uses laser platinum plugs and I used coppers. I doubt this can be the issue since everything is to spec. The plug gap is 1.1 like it's supposed to and the heat range is at 5 which is what it's supposed to be at.

CURRENTLY...

-The car isn't dieing but it is misfiring
-I have it running until it's completely warm

That's it. Please, can anyone chime in...

Figured it out, kinda...

My ignitor was getting a bad ground so that's why sometime it would start and it wouldn't other times. Also explains the wanting to die issue. However, it still doesn't explain the misfiring issue...

So went down to checkers and ordered factory spec ngk laser platinums and new spark plug cables...

Maybe the car didn't like the copper plugs I put in. Only way to find out is to replace them...

Stuff won't be here until 3 so I won't know until then.

In the mean time, any other ideas on why my car could be misfiring??

did you relocate the tire well harness?
I did, however, that shouldn't mess with anything since it's the body harness. It doesn't touch anything mechanically. Plus, the only wiring that needs to be cut and re-soldered is the wipers and that works perfectly.
hmm check coil?
I checked it according the fsm and the resistance is fine. So that wasn't the problem.

I had the same issue with it wanting to die. Ended up being the coil wire even though seeming like it was clicked down all the way it was barely good enough to start the car.

Turns out the starting issue was the igniter. It had a bad ground so that's why sometimes it would start, die, or not start.

My misfire issue was due to a TON of coolant soaking the plugs and cables. I don't know where the leak came from, but it's not doing it again.

Just removed my starter so going down to checkers to get it checked out and return the cables and spark plugs I bought for no reason.
