If you have spark and it won't run then it might be a fuel problem. Look for 60 psi pressure on the fuel rail. Sensors in that era ran on 8 volts but zero volts is not good. Scan for codes. And there is a camshaft sensor, easy to reach @ distributor, that may control ignition and injectors. All these sensors are on Ebay for about $10.
