Truck starts right up, but only at a super low idle for about 4-5 secs, then kicks up to a normal idle. Drives perfect with quicker response than before – but only if slow acceleration (bogs if laying on pedal) - until braking or slowing down, then stalls out and dies completely. O2 sensor not swapped out yet because passenger side manifold needs replaced and y-pipe disconnected from manifold on that side. Vacuum lines are either good or new.
EGR was so clogged, it was SOLID in the tube and PCV flow through tube on the driver’s side had to be dug out and then cleaned. I know, I know…
NOW, after replacing and cleaning all of those items, there’s a NEW issue – an exhaust smell in the cab!
It runs great when fixed properly and ran steady (even with what needed to be replaced) up to this point.
What’s even left after this point?
The PCM? Maybe a bad ground or connector somewhere? The O2 sensor?
Running rich problem is fixed; no fuel smell in exhaust; injector spray pattern looks right, but won’t hold steady; truck started to choke and “suck” air and fuel for a couple of days –fixed. The truck used to “whistle” while “sucking fuel from the TBI – fixed. What will make keep making it stalling and dying out now? Other than the O2, I'm at a loss
the heating system does not blend or just defrost or floor. It mainly blows out of the panel vents
After running a while it will do this causin problem through out the truck
I have a 93 Chevy Silverado 350 I have replaced the thermostat no leaks in lines burped the system and still no heat in the cab of truck
Has had problems not starting. Would start at others it wouldn't. Was driving it yesterday and it backfired and stopped running.
it needs to be greased
My truck starts up fine in the summer, but once the weather starts cooling off and starts dropping below 70 degrees or so it'll start up, run for 2-5 seconds and then die, if I start it again it'll start up and then die, eventually it'll start and stay started, and once warm it'll start up right away as long as the engine is warm, the colder it gets the more times it takes to keep it started, when it drops below freezing this becomes an hour long process. In the last yrar, the coolent temp sensor has been replaced, distributor shaft, battery, fuel filter, the fuel pump failed and was replaced 2 years ago. I'll smell gas as I try to start it.
Was just working fine then dropped 3rd and 4th. Just put it in as well had new shift solenoid put in.
I replaced the actuator in the left door and that door lock only works when the actuator rod has been removed, as if it isn't getting enough power. Now the right side door lock is inop as well. Is there a relay in there that could be bad, or is it something else?
I just purchased a '93 chevy k1500 from a
friend. It has been sitting for two years prior
to its break down. I was informed that when
it broke down a bunch of white smoke
discharged from underneath the truck. Also
the car would stay on but would not move
when put into gear. They attempted to try
and get it going before they towed it to its
final destination where it say for two years.
Now the car does not start at all. It truns
over but the lights dim everytime like its not
getting enough juice despite buying a new
battery. Took it to a shop to get fixed but
after a week there they were unable to get
the car started. They said there was no
power getting to the fuel pump and
distributor. They recommend me take it to a
shop to do the electrical work. I just got it
towed back to the house and now I'm
researching on how to get it up and
running. Any guidance will be very
appreciated. Thank you for reading.
