Default Problem w/ 95 Impreza wagon

I am having a very strange problem with my 95 Impreza Wagon. It randomly fails to start, due to the check engine light. I have taken it to several locations that cannot find the problem. The check engine light only comes on randomly, and when it does, it seems like it is not getting any spark. At desperate times, I have push started it, and the check engine light ticks off and it starts. If anyone has any suggestions on what the problem might be, that would be greatly appreciated. Thanks
Chris

The best thing to do would be to get the code pulled. It sounds like it might be the coolant temp sensor. Do you notice that it starts harder when it is warm out? I would go to auto zone, get the code pulled and go from there.

This car is OBD-1, so you don't have to go anywhere to get the code pulled. See directions at:

http://www.surrealmirage.com/subaru/engine.html

PS - The coolant temp sensor code is 21.

PPS - Many thanks to the owner of the above page.

If you read the first sentence on that page, it says that if you have a 95 or above you need a scan tool or go to a dealer to get the codes pulled. Subaru 95's have obd2.

Methinks you read too quickly. That page specifies LEGACIES. Imprezas changed to OBD-II later than Legacies, and even then, in the tranition year whether or not you have a car with a 1.8 or a 2.2l and manual or auto tranny determines whether the IMPREZA is OBD-I or II...

I don't read to quickly. That page says nothing about imprezas. I did not know that about Impreza's (obviously) . Which ones have the OBDII in the tranition year auto or manual? Do you have a link for more info on this subject? I have read about legacy's because i have one and i just assumed that impreza's were the same. You know what the say about ass-u-me.

OK then....I'll remember that the next time I'm hooking up the OBD-I connectors on a 1995 Impreza to read the codes.



redsubbiewagon -

Let us know how it goes. I think abosworth was spot on when he guessed 'coolant temp sensor.'

Mine must not have the OBD-I diagnostics because i looked under there and it looks nothing like the pictures and the descriptions. I have a few unconnected plugs, but none of them will hook up to anything in sight. I have replaced the coolant temp sensor in the past and it worked for about a week and then it started happening again.... I am thinking this car is wired horribly!! Well I will go out and keep fiddling with this car. thanks again and keep the suggestions coming.

I'd be quite surprised if that car is OBD-II. However, I've been wrong before. Did you check for an OBD-II port? It would a trapezoidal shaped connector mounted under the dash on the driver's side of the car.

Those unconnected plugs are probably your diagnostic plugs. There should be two green and two black. And something else that site Diz linked fails to include is that even OBD-II cars have these plugs for home diagnostic, test and reset of the ECU. You just need a chart of codes to use it. A scan tool just makes it all easier so you don't have to count CEL flashes...

Nice to know. I didn't know that you could do a self diagostic test with obd2.

Thanks for that bit of info. My freind has a cel on his impreza.

When I looked under there today, there was only one green and one brown, and they both were male plugs with two wires to each one.

I own a 95 impreza wagon that I've just scanned with an OBD II scantool. There's a plastic cover flap you have to open to get at the connector. It's on the upper side of a "pocket" in the dash just under the air vent on the drivers side next to the door. My car has a 2.2, is all wheel drive and has an automatic tranny.

It's OBD-I. just turn the key a little and the CEL will turn on (if the CEL is preventing the car from starting...if what I've read is interpreted correctly).

If you have the CEL on, just wait and it'll blink. Long blinks are the first digit of the code, and short/quick ones are the second digit of the code.

For example: 2 slow blinks followed by 3 quick blinks = CEL Code #23 (MAF SENSOR)

post the code that you get and I've got a Chilton's Manual that'll tell why the car won't start

cheers

Mine might be different because it is a manual and has a 1.8. I am getting fed up w/ this car because nobody works on subbies around here.

read my above post please...you've got the 95 Impreza L Wagon with the 1.8L engine and 5spd tranny. My car was the same until I swapped a 2.2L engine into it. The CEL codes will be the same as my car and I have a manual with the codes in it. It sounds like you're having issues with the camshaft or crankshaft positioning sensor.

drop a PM my way when you get the code...

cheers!
