Its getting fuel but has a very weak spark
SOURCE: 97 chevy 4.3 liter no spark no fuel pump running.
4.3 and 2.8 motors have a ceramic module in the distributor. if you have alot of miles on the truck, and there is no spark, that module is usually the culprit. easy to replace with a nut driver and some dielectric grease. mod is located in the distributor when you take the cap off look straight dowm and its right there.
also check eec relay and fuse. that will also cause the prob.
SOURCE: i replaced my spark plug wires and spark plugs and
check the ignition modual under the dist. cap
