You say no power, is that no power on both sides are just one? + side should have power with key on. If not check all fuses and relays. If no power on - side that comes from the distributor if it has one. if now power on the - side it is probably rotor or stator inside the distributor
Always check for the basics before replacing stuff to avoid time wasted and costs. Check for spark at plugs while cranking,use a plug with a gap stretched out wide to work coil and module.It should be a healthy crack when it sparks. Check for lack of fuel by spraying a carb or brake cleaner into open aircleaner while engine is being cranked.If it starts you will need to test fuel pump and power to it. Check compression,nil or very low indicates broken timing chain/belt/keyway or internal damage. I hope this helps,let me know your findings and we can work towards a fix.
Replace the sparks plugs, if the car is failing on one cylinder it will be hard to start. Check the air intake and the air filter, if air filter is dirty replaced, only to test the car try starting with intake open and no air filter, if it starts it is an air intake problem. Check the fuel filter and check that fuel have pressure, if fuel has no pressure it is either a faulty pump or an obstructed pipe.
Common cause for car not starting is distribution, with distribution rotor you often have to replace distributor cap or coil. If it is electronic distribution you have to scan distribution module.
If you have an anti theft system, this can also cause the car not to start, usually you unlock anti theft with car key.
If it is none of the above, it can be a car computer problem, the car computer module (ECU) can be scanned using a code reader at any good garage, in this case the mechanic will get error codes from car ECU and be able to troubleshoot further the problem.
