renovation · Post by **renovation** » Sat Nov 27, 2010 7:25 am

my 2002 Saturn vue just started this Tuesday or wednesday..
Started the car, drove it under a mile, parked, went back into the car and went to start it..it hesitated for a moment and started but seem to run ruff. i get on to the highway and it gets a lack of power, the check engine light is on. I drive it back to the house 1 mile and turn the car off . let it sit for a couple of mins and then try restarting it same problem. friend came over with a engine scanner that plug into the port under the dash . it came up with no reports !

sounds like a fuel pump problem? perhaps it needs changing. Sending you a PM.

If the CELs on, there is a code or more. Get someone to scan it with another scanner.

I have had my magnum throw a CEL, once, and not indicate any codes with both my scanner and the on dash diagnostics. Two days later the light went out. It was weird..

im going to run it up to the local auto parts and see if it reads the code !

Does the problem start as soon as you start the car or after you've driven it? If you're having problems starting the car, it's most likely a fuel pump. If the problems start after the car has warmed up, it could be a faulty sensor. Let us know how it turns out and good luck.

Mass air flow sensor(MAF) could also cause this.

There are many possibilities for this particular issue. You are fortunate that it is throwing a code though. Definitely check it out.

There are cars that can have codes that only a dealers diagnostic tester can see. Most generic type scan tools only pick up what the manufacturer has to make available by law, but not everything.

A bad fuel pump won't set a CEL, usually the car will just stall or fail to start.

What about the water pump with the Timing belt /chain? Might as well since its right there.

So, with a bad coil there should have been a misfire code for that cylinder. There wasn't?

Does that car have a t-chain replacement interval? Toyota's don't, when the chain goes on the newer cars it will be a disaster. Cars with t-belts have replacement intervals however but most manufacturers are getting away from those now.

Does a replacement chain then fix the design problem?
