: '96 STS starting trouble & heat only on right side

04-25-11, 09:14 PM
Hello, bought my dad this car seemed like a great deal at the time (one month ago). The biggest problem is when starting, it cranks and cranks before turning over. Once running it has a hint of rough idol to it. Took it to a shop and they told me it was the fuel pump, so a few hundred dollars later it has a new pump and still does the same thing. Now they say its the fuel injectors. Any ideas from your experiences?

The next issue is it was blowing cold air even on max heat, so they told me the freon was out. Another hundred dollars, now it only blows some what heat from the right side. So they told me it must the blend door behind the dash and it was a 14 hours of labor at $95 and hour!

Can't afford their guessing anymore so I turned here and found it to be very helpful. I pulled the codes like you all suggest to others, was able to find some of the meanings. Hope someone can help with the rest.
PC0603 = memory loss
IP1552 = loss of Kam
PZ1558 = PZM EEPROM check sum error

Any help/advice would be great and so helpful.
Thanks Landy
