1996 Subaru Legacy Randomly Will Not Start

Pull spark plug and check for spark.

Well it sounds like you have covered most of the bases.
One thing that could cause overheating is a restriction in the exhaust.
Do you know if the radiator fan is coming on when the engine reaches 220 degrees ?
How long can you drive it before it starts overheating, and does it boil over when it does ?

i would check the idle air control solenoid first. simply unplug it then remove the unit and inspect the air passage for any blockage and carbon buildup. Clean it if its dirty then test it out. If the IAC is good then you should look at the throttle position sensor.

i had the same problem with my 1996 subaru legacy grand wagon,which is identical to yours.it had a cracked head,the gasket was fine.not cheap to get done but id get it done now before more serious damage is done.

how does the car run for 8 sec rough? if so check the timing marks. if it runs smooth check if your getting fuel or spark. get back to me when you find out

Sounds like possible head gasket failure. Is it pushing antifreeze out through the over flow bottle? When it pushes out enough fluid the heater will not heat. A easy check if head gasket is to fill radiator and leave cap off and start motor. It will blow the coolant out wile running. I wish you luck. Have a good day.

Wired coil overs ?


Did you swap computers as well ?

You need to make sure that the grounds for the body and motor are good. Sometimes just turning the bolt will clean them up but better to remove, clean and replace. Also make sure battery terminals and wires are clean and secure. Hope this helps and have a great day.

Sorry if this might break your heart. I have '98 Outback which is the same 1st generation DOHC 2.5 engine. These are common head gasket problem (I'd say 100% of every engine sooner or later) once you have had your car overheated.

You will not get this comfirmed by just have your mech check the compression on the cylinder because we call it phantom leak (internal leak which can be confirmed with hydrocarbon in coolant). And then you will end up replace every other thing before you could reach the source of problem.

Other signs of this issue are as following: random overheating after freeway or uphills drive, bubbles in coolant overflow tank, oil residue in coolant overflow tank, bubble nioses from the a/c vent.

You're looking at $1000-1500 repair by independent mech as they have to pull engine out to fix the problem. I had mine fixed two weeks ago and now my baby is running like a champ.
