Angry '89 Caprice - no spark. Hmm....

Howdy, ya'll.

Here's today's dilemma: after a long rest down south, my '89 Caprice came back last night, and this morning I find it won't start - getting fuel, but no spark. Curious, with 108K on her clock, if it's time for a coil .. or something else?

I'll have to have my buddy 'scope' it tonight after work.. Any guesses from our resident techs ?

Have a good day. Mitch.

Like Larry said, or moisture in the cap. I've also seen the carbon button under the coil of the HEI that rides on the rotor fall apart too. Sounds like a tune up might be in order.

I'm betting on the ignition module, too... I thought of that after I got into work today. I guess she doesn't like being relegated to sitting over the winter as our "back-up" vehicle down south... poor old girl!

(and yes...I'll add pictures soon.. LOL)

O.M.G! "They" can say what they want about how good the Asian crap is - I've just discovered an original 1989 distributor cap and a set of wires that finally quit... after 108,000 miles. DANG!

Apparently it was all of the above - and I decided to just replace the entire distributor, since mine was disintegrating and the replacement was less work than replacing the module and the rotor that I couldn't get off. Not to mention the coil pick-up was rusty and disintegrating. Wow.

I've never seen a cap this bad in 30 years .. shame on me, and my Aunt Judy who had this car it's whole life before we got it... it just never ran 'bad enough' to warrant looking under the distributor cap! The dang electrodes are nearly burned off!

Good ol' American Chevy. That's all I could say..
