Why weak spark or no spark

SOURCE: 4wd lights flashing

I know the 4wd lights flash a code and I have replaced a transfer case control module on one before but as for the clunk and engine dying maybe it is a combination of more than one problem

Start with changing the fuel filter. If that doesn't do it, then change the fuel pump.

If you are getting power to anything else (such as the interior light) then this isn't your fix but, I had a similar issue where by 88 Raider ran fine but then would quit. I tested the battery and it was fine. However, the connectors for the battery were bad and weren't holding tight. I found it by pushing on the battery and one of the terminals just lifted off. Lucky is better than good sometimes.

These sometimes have problems with the magnet on the distributor shaft loosing magnetism. This causes the pickup coil not to be able to produce a strong enough signal for the ignition module and the engine dies because of no spark.
