Doubt it.
Sounds more like a leaking injector or fuel pressure regulator.

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

Take off the distributor cap. Check the star wheel that is splined to the distributor shaft that the pick-up coil uses. Make sure this wheel is not loose on the distributor shaft. It is right above the pick-up. If it is loose, replace the distributor. This is a common problem. If it needs one, all the part stores stock the distributor.

Check the injectors. They are really bad about leaking on the 4.3's.

After hot engine wont start and smells like gas


Most likely causes are bad engine coolant temp sensor OR leaking fuel injectors. Bad engine coolant temp sensor will give computer false reading and computer provides wrong air fuel mixture. Leaking fuel injectors will load the engine with raw gas--just like flooding it. Try pushing the gas pedal to the floor and holding it there when cranking when hot. That forces the computer into "clear flood" mode and it shuts off the injectors. If it starts up with pedal down, that would be a sign of leaking injectors.

Sounds like it was flooded. Next time it happens. keep gas pedal all the way to the floor and hold until it fires. water in the gas, or just bad gas can do this. But if you pumped it at all while trying to start it if fuel injected can flood it. Let it sit and try again, or keep gas pedal to ground and hold until starts.

I think you need to get to a mechanic. If you smell gas, then your fuel pump is pumping it out, gas is not getting burned properly and it is being dumped either via a leak or incomplete combustion. You have some type of problem with your intake or combustion system which needs attention.

Not sure about the idle speed thing, but it sounds like one or more injectors is dripping (not fully closing). That would cause the smoking/gas smell. You should take them out and have a specialized shop like RC Engineering clean them. Might also be the idle issue.

1987 k5 blazer dies during driving


Make sure your battery is secured by a good battery hold-down system...if the battery shifts in the tray and the positive terminal touches the fender, the dead short will immediately kill the vehicle.
Also, take the alternator to a parts store and have it tested if your battery is held down firmly. The whining noise can be bad alternator bearings. On a vehicle of this vintage, this is a possibility for the noise. It is furthermore possible that the alternator has died electrically, and during a lengthy drive, the vehicle's own electrical consumption will drain the battery and the vehicle will die en route.
When you jump it off, it gets enough charge from the donor vehicle to drive, but if the alternator is dead, it can't keep the vehicle supplied with enough energy to operate.
