Sometimes hard to start after and then runs slugish

In order to help you, need a little bit more info here. Is the check engine light on? Did you recently disconnect the battery for any reason?

SOURCE: hard to start and smell gas
have 1994 4.3 cpi and the problem I had sounds same.
It was a leaky pressure line in pletium . easy fix $45.00 part $15.00 gasket.
the leak was caused from the fuel lines rubbing together in pletium.
take the vortec cover off ,then remove air regulator in middle and look inside . I turned on power to key and gas spray came from drivers side of pletium looking in hole.fuel line side. if gas spray on passanger side then gas regulator faulty. takes 5 min to check
After fixing truck runs runs great. no more gas smell in cab.
also you can smell oil for gas

check airflo sensor or potentometer,throttle pos sensor; if revs are to low when turning the wheel the power steering pump will draw power from engine, causing your other problems

Check the fuel pressure regulator. generally "failure" position is full open which will richen up the fuel mixture. also check vacuum line to the regulator for cracks and good connection.

Your vehicle as an ignition control module located on top of the distributor (under the cap and rotor) I would pull the ICM and take it to NAPA and have it tested if bad replace it (cost about $80). Sounds like a ICM problem or it could be the ignition switch located on the steering coloum which can't be tested but costs $20. Hope this works
