Question about 2002 Saturn VUE
About a month ago I started having problems w my vue, it seems to start when it wants to. We changed the fuel filter and thought we had it fixed. Well last night I was stranded again. What could it be?
I don't know where to start.
We've heard battery, fuel pump, crank censor, spark plugs, security module.
Non-start situations basically boil down to two things: No Fuel, or no spark.
I you are looking to throw a part at it, start with the crank sensor. They are cheap and not too hard to replace.
A full diagnostic approach would be to determine if it was a fuel or a spark problem. Check fuel pressures with a fuel pressure test guage: Low fuel pressure indicates a bad fuel pump or a bad fuel presssure regulator. Lastly on the fuel side, check t see if the injectors are getting a signal to fire, usually done with something called a noid light, I believe.
Spark diagnosis begins with first determining the condition, then finding the cause. Bad coil, loose wires, even the crank sensor are all suspect. A good repair manual with a flow chart is probably the best procedure to follow.
In my case, my manual only had a passing reference to the crank sensor and no diagnostic procedure to test it or even lead me to it. I found the solution through extensive web searches. Once I replaced it, all was well.

I know this is the last thing you want to hear, but if you have a check engine light on you need to scan to get the trouble code. The only thing I can think of is that when you filled up you may have filled up too far and gotten alot of fuel into the evap canister. I know this sounds funny, but if you keep filling the tank up all the way till it's almost coming out you may been inadvertantly getting fuel into the evap canister. You won't know this for sure until you scan it though. This is usually a problem after continuous filling up past the "auto stop". In other words.... When pump stops. Stop pumping. I really hope this helps. This is all I can come up with without actually seeing the car.

First thing is to check for codes which would indicate if you have an ignition module issue, a crank sensor issue or possible a PCM issue. If you do not check for codes first you will create new ones and then determining the problem will be alot more difficult.

Kindly tell us whether your engine starts up properly to idle . If yes , then your problem is with the transmission system or with the clutch plates . If the clutch plates are too empty , the gear would be almost stuck . If the car is in N-neutral , try pushing it and while moving slightly try to change the gear . Engine oil and transmission oil should be checked up regularly .
At present situation you will have to have your gear system unjammed or opened up by a professional and have your gear box replaced or checked for jammed gears which is pretty time consuming and difficult job . Else you will have to replace the clutch plates and youre ready to fly again .
Thanking you , Dixon Dominic
