Hi, I'm a newbie posting, though I've been frequently gaining knowledge from this site and it's talented users. Thank you for the invaluable knowledge that could've only come from the stories told about problems solved.
I have a 98 LSC with 140K and I've owned it for 2 years and aside from having to fix the blend door I haven't had any problems.
One day the car stopped starting. Actually the day before it did start rather harshly - ran rough, then I shut it off. The next day it just cranked.I thought it might be the fuel pump so I checked the pressure - 38 psi.
I sprayed starter fluid in the intake and I got no change in engine response. I also pulled a plug and had my girlfriend crank the engine but I saw no spark.
I then replaced the crank position sensor since that is a popular problem but that did not change anything.
I unplugged/plugged in the cam position sensor but still nothing.
I then bought an Innova 3140 code reader but it said the [Mark VIIIs]computer did not have any DTCs stored.
I really thought I'd have this figured out by now but right now I'm at the point were I'll just start unplugging/plugging in all the sensors without much of a method. I'd really appreciate any advice anyone could offer.
