Trouble starting

Thanks for the reply. This morning in Chicago it is around 30 degrees. The car is in the garage and I recorded the starting of the car this morning. It started successfully twice with no hesitation which is the normal way it would always start. We cannot tell anything from it other than the way it should be. I do smell exhaust when starting but that should be normal as it hasn't been started in about 3 days. I neglected to see if there was any black smoke from the exhaust upon startup.

I will need to take it to get the scan tool and run it through to see if any codes come up.

I will let you know what else I find after the car starts after it has been warmed up.

Here is the video of the cold start this morning. Let me know if there is anything else I can record.

Okay, here is an update: I had took the car for a drive and sure enough after a short rest it hesitated on the start. I also have a video of running the scan diagnostics.

Hi Joe, my apologies for the long delay in responding. Holidays and winter weather do not give us a reason to use the Firebird in Chicago. Thank you for your assistance but I am not sure what I can do going forward.

The scan tool I used was available to me at no charge at my local auto parts store so its limited to what you saw, it records codes and gives the replies.

I assume a mechanic would have better tools, I assume?

As far as the sensor(s), if there are more than one are these easily changeable? In other words, without going from the bottom, can I start changing sensors if they are reasonably cheap? I am somewhat handy, I fixed my supercharger on my 3800 Regal last summer, and have some tools that allows me to work on it a bit.

What I fear is dropping this off at a mechanic, even if I trust them, they might be guessing on what the issue is as well. I feel like this issue has been encountered before.

Let me know your thoughts when you have a moment.

Hi Joe, I have an update for you.

In Chicago we have been going through some extreme cold and lots of snow but in between storms I was able to take it to my mechanic.

The short of it is that the Fuel Injection Pressure Regulator was faulty. There was also rust on one of the posts of coil 3/6. Not sure the coil was contributing but these two items appear to be the solution here. Thankfully, it wasn't too costly but like anything else, everything needs its time and money to repair and that is fair.

I am not sure if I can find a great video that illustrates or gives me assistance on where and what it would take to replace the regulator but I have a feeling that I probably could not have done this myself. Mainly because of the location and the tools I would need but also how to get the car started after the new part was installed because it seemed like there was a process that needed to be followed. Not to mention I don't do work under the car and dont have all of the tools, T-bits, like a shop would have on hand.

I would like to take a moment to say thank you for the assistance you have given me this entire time.

I actually have another question I am going to post about my 1999 Buick Regal GS, supercharged, as I have a service engine soon light on. I have clear codes on that one but this doesn't appear urgent as it comes and goes.

Thanks Joe. Take care.

John
