take the coil negative primary wire off the coil terminal & set it aside(dont let it touch anything). key on, eng off. With a jumper w 2 alligator clips jump from this(coil pri) terminal to ground like morse code & see if you have spark from the coil secondary wire held 1/4" from ground. that's the coil check.In this case not likely dist pickup but if you have a spare dist plug it in(key on,eng off) & spin it by hand & see if you have sparks. this checks the dist pickup. the ECU, you can have your parts house check it but it really needs to be hot for a valid test so If you have another you could sub it in the check the ECU.
