Re: 1987 suburban no crank or start
Does the Check Engine light come on with the key on? If yes, check for spark at one plug wire end and check for injector pulse (you'll see it spraying fuel on top of the throttle plates while cranking). If no Check Engine light, look into a loss of power to the ecm. These bad boys are pretty bullet-proof. I've also seen the rotor worn completely through and the spark then kills the ignition module. Let me know what you find and we'll go from there.
