I'd take a look at your timing chain...normally there is a "silent" cam responsible for the spark~


Your timing chain has broken. To conferm this, remove a valve cover, crank the engine, and watch for movement of the rocker arms. My guess is you'll see no movement which means that the camshaft is not turning which means the timing chain has broken. HTH. -Jim

check the distributor itself but like said before, probably the timing chain broke. Which translates to $$$
