Hello AF community!
I have been given a 95 S10 Blazer 2dr because the owner could not afford to have it put into the shop. Literally, GIVEN. Anyways, to start off the battery was as dead as it could be so I gave it a good 2 day charge and started troubleshooting. Here are some symptoms:
Problem cranking (acts like its not getting proper fuel, or maybe too much? However, I don't smell fuel like its flooding out)
IF, it cranks, it will idle very rougly and usually die shortly after
IF it doesn't die shortly after cranking, any attempt at using the gas pedal causes a rough/irregular throttle response usually followed by it dying.
The VERY first time I cranked it after charging the battery, it cranked perfectly and drove/idled as smooth as ice. I let it idle for about 30 minutes making sure it wouldn't overheat or anything else. Everything did fine, I killed it and cranked it again later THEN encountering the problems described above. It's been the same since.
So, some of my guesses (keeping in mind I'm not very familiar with these vehicles) some type of sensor (crank/idle), bad vacuum leak or a loose connection somewhere in the electronics. Looking for some type of confirmation before I waste money throwing parts at it.
Also, included a short video of what it's like trying to crank and running.
