| some pictures showing the whole construction and some of my comments: This one was totally dead (#4 cylinder) - infinite resistance reading. Here's what they look like - for those not familiar
 An exploded view -- all the top plastic broken away.
 A second shot
 Here's a how things fit together
 The metal cap and other parts
 A better shot of the cap and o-ring from the perspective of what goes inside the body of the injector
 My observations.... - The coil assembly DOES NOT fit tightly on the metal tube that attaches to the metal top cap. Gasoline is easily able to contact both the cap o-ring as well as the grommet wire insulators. - The grommets were NOT in real good shape. Since they were not embedded/molded into the upper Red plastic cap -- pretty sure I didn't damage them (more) when things came apart. - After passing thru the metal top cap + grommets the connector wires go right into the plastic coil assembly can. The can's opening for the wires was pretty large (elongated) - hard to tell how well they were sealed up? My impression is not real well -- looks like those grommets were suppose to press down into the plastic as well? - Seems possible that if the wire grommets leaked a bit that gasoline (+ ethanol) would come into contact with the injector's electrical terminals. Can't say for sure if some of the gas could eventually make its way into the coil plastic can? - It also seems possible that some kind of electrolysis reaction could occur to the injector's metal parts (since body is well grounded) -- but visual inspection of the internals showed everything looking clean! - Later, I did get the coil pack housing apart and found that at least one part of the coil's wire was separated and another part very brittle - breaking easily. The rest of the wire was in pretty good shape? This seems consistent with the coil windings shown in the first message posted for this thread.
