I’ve been working on a friends Jeep Wrangler that won’t start and am at a loss of what to try next. It is a 1993 Jeep Wrangler that is getting no spark to the distributor. I have replaced the ignition coil, distributor cap, rotor, and the crankshaft position sensor. Still no power. What is my next step to diagnose this?

See if it’s getting spark at the coil. If not, see if it has voltage at the positive side of the coil primary with the ignition on. If no voltage, find out why not.

Some dealerships (mine included) have certain techs that only do driveability concerns. Crank no starts are a driveability concern. To make money in this line your need knowledge of the system,experience(the best comes from failure) and a logical mind,along with your test equipment.You need more knowledge about the system your trying to fix.The skills that a auto tech has are valuable and hard won.A mans got to know his limitations.
