Is there electric to the ignition?
Does it turn over at all?
Some more info might help...
If you don't get an answer from this forum, there are other places online to look...?

Also, you could try getting the codes from a code reader that pplugs into your dash. They're kinda cheap now-a-days and might even be able to be rented from an auto parts store.

I was driving down the road all is fine. Then i pressed on the gas and nothing happened nor raise of the rpm's didnt speed up and then i heard a large gunshot like sound. Then my car just lost power. Steering wheel locked up and all that like running out of gas. The car didnt shut off. It just idle and no rpm raise when stepping on the gas. Then i tried restarting it. When i tried it just cranked. It wont like spark and fire up the engine. It alll works when i turn the igniton it acts like its gonna start up but then just cranks forever!

Sounds like your transformer (AKA coil) blew. Check for spark.
It takes 3 things for an engine to run: compression, air/fuel in the right proportion and spark at the right time.
The only way you lost compression that quick on all cylinders is to break the crankshaft. If it ran after the gunshot, it is unlikely the case. Does the belt move when you crank it?
