90 eclipse not running

1990 eclipse 2.0 dohc distributorless, car stopped running, replaced plugs, wires, coil packs and controller, yet still not starting, spins, no fire or fuel inj pulses, thinking it might be the crack position /cam sensor was told by dealer could be good thinking but to replace it is over 500 dollariniez, can i get just the elecronics for this or do i have to replace the whole thing??? car ran great till it just wouldn't start one morning/ wife daily driver not a racecar driver.

Try and get a junk yard one........sorry to tell you, you'll have to get the whole thing, cant just get the internals.
