1993 Chevy S-10 6 cyl Four Wheel Drive Automatic? Miles
I bought a 1993 s10 Blazer 4.3 cpi, that was not starting by itself. The fuel pressure shows 55psi when you turn key to on and does stay there. When you crank it over, the fuel pressure drops to a few pounds and the engine does not start. It has had a new distributor with a new module installed, fuel filter changed, and all of the fuses checked and are good.I found that the engine will start right up if it is primed manually. Also what I found is that after running the battery down and attaching a battery charger, the fuel pressure shows to be at 60 psi with the key turned to the on position and will start right up with no priming involved. The previous guy who owned this told me that the only way it started with him was to jump start it. After it is started and the battery charger removed, the engine will start again right away. With the battery charged, the engine will start every time for about up to 30 minutes after the battery charger was installed with 60 psi still showing on the gauge with key to the on position.I can wait about 2 hours later and try to start, and I'm back to no start without a prime, or by simply hooking up the battery charger and seeing that the fuel pressure was at 60 psi. I, m lost.
