Hello James, Had my distributor go bad and replaced it w a new one. Installed the new one and it ran great for the day. The next day I went for a drive and then the vehicle started to run really bad. I believe the distributor slip because the hold down bolt was loose. Then ever since I can’t get it to run good or timed. I thought maybe the timing chain jumped so I replaced the chain and made sure the gears were aligned. I also replaced the coil, wires and plugs and the distributor (Autozone) and rebuilt the original distributor. I followed the procedure to install the distributor from the manual and a Youtube video ( https://youtu.be/dskRwrNa5Fo ). This is making me go crazy! Any help would be appreciated!1994 Chevy Blazer 5.7

Send me the VIN off the vehicle and I will try to locate the correct information for installing the distributor for you.  You Tube is a great resource, but sometimes the information you get is not correct.

Ok, ThanksWhen i first removed the distributor I did make a mark on its position
Chevy Mechanic: J Hall, ASE Certified Technician replied 1 month ago

Here are the documents I have available.  The first one explains how to check the timing using a scan tool.  Since the vehicle is a 1994, you will need a scan tool that can access OBD1 programming.  The second document explains how to correctly install the distributor when replacing it.  I suggest you follow that document exactly as printed before trying to check the timing per the first document.  I hope this information helps.  If you need anything else, please let me know through this chat box or open a new thread and ask for me by name, J Hall, and I will do what I can to help.  I wish you all the best, ***** ***** you for using JustAnswer.
