2003 Mitsubishi Galant

Ok I am a fairly decent Mechanic and I am definitely not new to the game but i have one that has me completely stumped. This is my daughters car so I know all the history and this is the first time we have had a problem with it. 2003 Galant 2.4. Died on her as she is going down the road. My first reaction was great she ran it out of gas, but no she has just filled it up. So to make sure it was not the pump/relay I sprayed it with b12, no start. So we got it home and I checked the coils and I was getting no spark from them so I replaced those and the plugs. Still no joy. Tried the crank and cam position sensors still no luck. Ordered a computer and had it programed and still no luck. PLEASE HELP, I am ready to stick some c-4 under the tank and send it rolling off a cliff somewhere

Maybe you just haven't thrown enough parts at it yet.
Here's what you should have been doing
All "crank, no start" conditions are approached in the same way. Every engine requires certain functions to be able to run. Some of these functions rely on specific components to work and some components are part of more than one function so it is important to see the whole picture to be able to conclude anything about what may have failed. Also, these functions can ONLY be test during the failure. Any other time and they will simply test good because the problem isn't present at the moment.
If you approach this in any other way, you are merely guessing and that only serves to replace unnecessary parts and wastes money.
Every engine requires spark, fuel and compression to run. That's what we have to look for. Just finding it failed one of the tests isn't good enough. We need to see the whole picture.
These are the basics that need to be tested and will give us the info required to isolate a cause.
1) Test for spark at the plug end of the wire using a spark tester. If none found, check for power supply on the + terminal of the coil with the key on.
2) Test for injector pulse using a small bulb called a noid light. If none found, check for power supply at one side of the injector with the key on.
3) Use a fuel pressure gauge to test for correct fuel pressure, also noticing if the pressure holds when key is shut off.
Once you have determined which of these functions has dropped out,
you will know which system is having the problem.

Ok I tested the injectors and they are firing, I then tsted for spark and like I said in the previous post there is no spark. I have not had a chance to test the fuel pressure yet. But apparently there is no spark and that problem needs to be addresses first. Now like I said in my previous post. I have changed the coils and plugs, cam and crank sensor. Any ideas will be helpful.

Not if your going to lie about the testing.
Believe it or not, we do know what we're doing and we do have a reason for doing everything. I have a lot better things to do that argue with someone asking for my help.

Ok look if you aren't going to help then let someone else try and help me. IT ISN'T FUEL, IT IS GETTING PLENTY OF FUEL. No I didn't test it but I don't need to I know it is getting fuel. If it was getting even a little fuel and spark it would try to run. It isn't even trying to run it HAS NO SPARK! Now if you are done playing games and wasting my time and want to help then great and I appreciate it greatly, but if not then let someone else help please.

I just tessted the coils nd they are getting 10.74 volts. I don't know what they need to be able to fire off but I would think that would be enough to give a little spark but I am getting none through the tester I bought. The one that I got is an inline tester that hooks to the plug and to the plug wire.
