Re: Scan tool

Car starts runs fine until you shut it off then it is a long hard start

Re: Scan tool

If there is no service engine light I would check fuel pressure. And the fuel pump

Pull the codes. They will help isolate the problem(s).

Re: Scan tool

That is the problem it will not link (scan tool) with DLC (under dash) It tells me with two seperate tools bringing up codes is not possible. I just tested both tools with a different vehicle and it worked. These OB1 are not Gm best effort Its a hit or miss and you can throw a load of parts at it . Had the same problem in 1989 the Z24 would just die any where at any time!

Re: Scan tool

Do you know anyone local that has a professional grade older scanner like a Snap On referred to has the brick or a Mac. While the hobby grade scanner might work on some cars others cost more for a reason
