Hi, if you have that spider fuel system, that is always the first thing I suspect, if there is any kind of spark. Can you check fuel pressure?

Did you check primary voltage to the coil, the primary circuits are the small wires. The pink wire goes hot when you turn on the key, use a voltmeter, does it show battery voltage?

Did you clean out the dist. Cap and check the rotor? Can you check for codes?
