What could be wrong with a 1990 Geo Prizm if the coils are new but there is no spark?

Im guessing you have already checked the plugs. Make sure there is power and a signal to the coil. Bad crank position sensor can make the coil not fire. I found the the answer to my own question! Timing belt broke.

What is wrong if i am getting no spark on a Mazda protege 5?
Change the coils they should be two black blocks on top of the engine..the coils could have gone bad.
Whats wrong with your 1990 Chevy lumina if the spark plugs are not firing?
you are not getting spark. this could be from a bad alternator, bad spark plugs, bad spark plug wires, or bad engine coils. The spark plugs and wires are the cheapest so try putting in new ones of those first.

Your check engine light comes on when your car shakes what is wrong?
When the engine light comes on and the car shakes at the same time, it could be the spark plugs or ignition coils are faulty. Misfiring is causing the car to shake.
If the Air conditioner evaporator coil keeps icing up what is wrong?
Could be several things...It could be low on refridgerant or the coils could be dirty. Check the coils first as this is something you can do your self.
What could be wrong with a 1994 Olds 88 that has trouble starting when it is raining or cold outside?
check the coils .they might be bad I'd try plugs/wires and fuel filter first. If it backfires when revved up while running rough, probably a spark problem, plugs, wires, or coils. But could also be a fuel problem (filter or water in gas).
What else could be wrong if 2 cylinders are misfiring after getting water into the motor through the intake after the spark plugs and ignition coils have been replaced and it is still misfiring?
I really hate to be the one to tell you the bad news but it is possible that you have bent some valves. Take the spark plugs out of the missing cylinders and run a compression check on those two.
