Default Cold Start Problem

Hi, I have a 1997 GX Subaru Impreza Automatic Sedan. I have had the car since new and it has always run trouble free up until now. In the last few months sometimes when I start the car in the morning it wont start, then after a few hours it starts ok. Once the car is running, performance wise it runs great. I took the car to a dealership and they done a computer analysis on the car but it showed no errors. Their thought was wait until it breaks down completely then they will be able to identify the problem. I had a road service mechanic look at it the 1st time it happened and he thought that there was no spark and the problem was the coil. I have since been told by the dealership mechanic that the coil would not break down then be ok again. Another mechanic thought that it may be a crank angle sensor but I have been told these usually break down when the engine is hot and not when it's cold. It seems that for some reason there is no spark through the coil then all of a sudden it is ok? I have also had it suggested that the problem my be in the ignition component that sits under the coil. Another mechanic suggested it may be the air flow meter and yet another has suggested that it may be the computer, and finally yet another has suggested a fuel pump. Each time someone has looked at it its has ended up starting and therefore difficult to troubleshoot the problem. Has anyone experienced this problem before and if so what fix have they come up with. I could cost me a small fortune to replace ALL the parts just to find the right one and there is no garantee that it will work after I did.

any help would be much appreciated

Thanks

John Calder

Unfortunately, the only way to diagnose this problem is to wait until it won't start. As far as the possible causes mentioned by those differant mechanics, they are just that, "possible causes", and yes it will definately cost you a small fortune to change all those parts.

Imo, your better off paying one towing charge and then having it diagnosed correctly, as opposed to "tossing a dart" and hoping you hit the problem part.

Hope this helps

Default Me too... Cold Start Issue

My 2000 is doing the same thing, but was fine in the winter prior to getting a new starter put in this spring about a month ago.

Then every morning that it's been cool since, or anytime it's been sitting for long enough with cool weather, it takes 2-3 tries to start. It's just about turning over each time. When it does it's bogging and only at 500 rpm's, I give it a shot of gas and then it jumps up to 2000 or so and settles back down.

The two time's I've taken it back to the shop it's been hot out, and they've had no issues getting it started, and say the computer is telling them nothing.

Let me know if you found out what was wrong for you... or if anyone else knows what's up!

This thread is four years old and should not have been bumped.
Problems of this sort should be posted in the Service and Maintenance section, not here.
