Picked it up from the shop. Havent drove it all week, been driving my F150. Couldnt figure out where there noise it was making was coming from. Turns out both u joints on the front shaft were shot. Doh! Could have fixed that my self. Oh well..
It always ran kind of weak, compared to other Vortec trucks ive driven. I just blamed it on 291k miles. The morning i was going to drop it off at the shop it was very humid out. It would crank and crank but no fire. I thought for sure the fuel pump was dying or the crank sensor went bad. My old man said he bets moisture got under the distributor cap. Sure enough. Turns out whoever replaced the cap and rotor broke the pot metal ears off the distributor that hold the cap down, only one screw was holding it on. I cleaned the points off, and used a tiny c-clamp on the broken ear and now it runs stronger then ever.
