Have a 98 chevy 1500 5.7l, 2 weeks ago it stalled, after several tests I noticed the rotor button had marks on it from where it was rubbing the cap. I pulled the distributor and noticed the gear appeared in good shape, but of the two steel washers between it and the composite housing only very little of the stationary washer was left. I replaced the distributor, the cap, and rotor. It ran for 2 days, then fuel pump quit, replaced it, it now gets 65 psi and 70psi while cranking. It does have spark, but no start. This engine has 45,000 miles since rebuilt a year n a half ago.
Ok so I would stick with the no spark issue to keep it simple and not worry about fuel till we know we have spark
remove dist cap and number one cylinder spark plug
turn engine by hand till number one piston is at top of compression stroke you can check by inserting screwdriver in spark plug hole and turning engine checking for top of stroke when it is at highest point take a look at distributor rotor and see if the rotor is lined up with the "8" that is stamped into composite housing and reply back
