Got everything ready to go yesterday, bumped the starter and got a click, then a thunk; then nothing. Swapped batteries with the one in my 2000 Chevy, same result. Went to O'Reilly's and got a new starter, the one speced for the '98 GenVI 454. It's a high torque, miniature lightweight; much better looking little spinner.
It also uses bolts that don't fit any other starter - I had longer and shorter. Back to O'Reilly's for the bolts - which they didn't have. But, there got to be confusion as to whether they were metric or SAE. I had to go home and check (they are 3/8-16). This am went to Ace and got grade 8 bolts, extra thick washers and AN washers.
Starter works, engine turns over. So next I hit the fuel pump switch - no noise.
Got out the volt meter - it has juice. There's 2 bolts on the top of the pump - so I took them out. It looked like one of the brushes was not in it's socket - but maybe it fell out when I took the cap off. I turned the armature (or is that a rotor) and it seemed jammed up at first then turned freely. It was a real trick getting the brushes back in and the cap back on. But, then the pump worked.
Set the fuel pressure regulator and cranked the engine over. It's got spark and fuel, but apparently the spark is not talking the same language as the valves. Ran out of time. I am now armed with new info about setting the correct timing and ready to give it another shot tomorrow afternoon.
Oh, did I forget to mention there was fuel dripping out of the secondary throttle shaft? I'm ignoring that for now.
