Depends on the level of failure. A weak coil may give a spark but not be strong enough for sustained operation. But don't jump around with your diagnosis. Test the engine in the logical order I described until you find the problem. Playing a guessing game will cost you more time and money.
Also, you must be specific with your questions in order for me to help you. Just because there's "Spark" doesn't mean all cylinders have spark or that the spark timing is correct. If you did a complete and thorough check of the ignition system, then I have to know this. I get a lot of questions and I can't guess as to what someone has done or didn't do.
Also, you said you have "Fuel", but you didn't say what you did to determine this. Did you do a fuel pressure test? If so, was it while the engine was cranking or just with the key in the "On" position. And if there is good fuel pressure, that doesn't mean the injectors are giving it to the engine. Did you also check the fuel injectors for firing and spray pattern?
What ever you did during your diagnosis, I need to know in order to narrow things down.
