1991 Chev GMT 400 6 cyl stall out issues
Jeremy N Meagan Gardner posted a question in Ask the GM Technician
I have a 1991 Chev GMT 400 6cyl. It has approximately 175,000 miles on it . I recently have put a new starter ,water pump , fuel pump ,and battery in it within the past 2 weeks. Plugs, wires , and distributor cap and throttle ppsition sensor (i believe thats what its called) was changed about 2 yrs ago. However ,I've been having an ongoing issue with it that has been there since I purchased it and I can't figure it out. Whenever my truck is in idle it will sputter and stall out. It will sometimes sputter and stall in park . when I change it from park to drive, it will sputter and stall out every time. When I'm in drive and I come to a stop it will sputter and stall out ,unless I press the gas pedal too then it will stay running. Also when I'm in reverse and stopped it sputters and stalls out. Also I noticed if I'm in park and its running fine ,when I cut my wheel as far as it will go ,that will cause it to sputter and stall out. But like I said in park its very iffy , sometimes it'll run OK and sometimes it'll stutter and stall out. Other than that the truck runs fine as far as driving it goes and this sputtering and stalling out is the one issue I cannot figure out! I'm hoping someone out there knows what it is BC I have no idea and I'm hoping it'll be a quick ,easy and above all cheap fix . I bought the truck in 2017 and it had this issue , and it did sit for 2 yrs ,BC I used my car to get back and forth to work. But I believe I cracked or blew a head gasket in my car so I know that's gonna be an expensive fix. So after sitting for 2 years I decided to fix whatever it needed so I could get to work. And the things I had to replace within the past 2 weeks was the starter, water pump, fuel pump ,and battery. And also new tires . so hopefully I have given enough info to help y'all figure out what it could be . thank u for taking the time to read this and for your knowledge that you give to help me out. I'm not a mechanic ,so if you can , please be very specific on answers so that way I can know for sure what you are talking about . thank you! -

alternator reads 13.6 volts charging. Voltage on the dash is 12. As the vehicle runs the voltage drops slowly until 10 volts. Any suggestions to what the issue is? Brand new battery solid ground on it and positive.

I have a 1991 C1500 5.7L that wont start. The truck had not been used for several years. I was able to get it started and it ran fine a couple times. Then the next weekend I went to start it and it would not start. It was backfiring some, so we chacked the ignition and found some corrosion in the distributer cap and wires. I replaced the cap, rotor wires and plugs. It seemed to solve the backfire but still no start. It has good spark which jumps across an HEI psark tester. The timing is good. It has a good flow of fuel from the injectors, but it just cranks and does not seem to even try and start, unless you floor the accelerator and put it in flood mode, it seems to kick over a little but no start. So far the cap, rotor, wires, plugs, ignition module, MAP sensor and coil have been replaced. The temperature sensor, TPS and oxygen sensor test good (reads correct value using WINALDL). Even though it has good spark and fuel it doesn't start. Suspecting fuel being too rich wedisconnected the injectors and tried some starting fluid and it does not start with it either. We are out of ideas right now. Any suggestions? -
My name is Cody. I'm a Georgia boy. I was recently passed Down my dad's 1991 GMC Sierra and it is in bad need of a paint job. I was thinking about white, black, or painting it back to it's original color. I'll be painting it next month, so let me know what you guys think. Thanks!
