88' 245 w/ 125k wouldn't start this morning. Car is cranking great but no combustion. Tried starting fluid by taking out intake hose near intake manifold & squirting in. No response. Figured problem is spark. Replaced older cap & rotor w/ new. I have another 240. Tried switching coil wire. Tried starting with AMM uplugged. Unplugged then plugged back in ignition module (this worked once on another 240, apparently slight corrision on plug). Just to be sure, replaced fuel relay with known good one. Spun & checked fuses for corrosion. Coil is only 1 year old but will try switching with know good one (BTW, 2 coils bad on 2 different 240's within last couple years, first ones I've every replaced in 30 yrs.) I can look at plugs but they're only 25k old. I did check wire connections to plugs & they're all good. To be positive problem is spark I'll ground plug wire & look but if it is spark & coil isn't the problem, must be Hall sensor? This is in the distributor?, anyone have any experience here? Thanks.
