2002 Blazer "Check Engine Soon" light is on but when we hooked up the scanner it doesn't show any codes. I need to get it inspected, but I can't if I can't find out what's wrong.

It may be that at the ALDL connector has no power for the scanner? Something not working electrically inside the vehicle?
thighland answered about a year ago
car runs great and no apparent electrical problems. Only thing I know is wrong is slight power steering fluid leak. Everything else is good.

Gotta get a code or it is a guessing game. Would need someone to look at it to see why the light is on.

If it is the yellow check engine light that is a maintence reminder light, time for an oil and filter change then reset the light, if it is the red light and no codes then there is a failure in the engine control systems, check the fuses and don't forget those under the hood, if none are blown then you will have to go to a shop for further testing.

It's a yellow light. You think an oil and filter change will do the trick?

1989 Chevy Blazer, just had complete service performed 2 weeks ago. For the first time, my "check gages" light came on. I noticed the oil pressure was zero. Never saw this before. I check the oil (and while it said to add oil (weird since I just had the service), it still had oil on the dip stick. Is driving dangerous? Will my motor burn up? What shall I do? 2 answers

1990 Blazer just stoped running the other day and is not getting any gas to the fuel injectors.I checked the fuses to see if that was the problem and they where good. I was having trouble with power surges when driving at a steady spead on Freeway. I replaced the EGR valve because I was gettin a engine light for that before it stopped running. Are they related? I tried putting the old EGR valve in after cleaning it and there is no change. I don't know how to determine what else could be wrong. Help. 2 answers
