1990 subaru legacy won't start


Recommended Posts

So I just traded my old Toyota pickup for my first subaru , I got the subaru it didn't run the guy just told me it was the fuel pump so I replaced it and fuel filter , but still won't start, I'm getting fuel, but there is no spark I checked fuses they are good, I did some looking around and people talked about sensors maybe but I'm not sure How to test them , and not sure what else to look at, it cranks but won't start.I was going to replace the ignition coil but I thought maybe I should ask first sense it's my first subaru

So I cut some tape and still won't reach its all tangled up in the bundle of wires , is there any way or will I have to cut all the tape for the whole bundle? And would a battery possible cause it not to get enough power to start ? I hooked up jumper cables but it could be a bad battery? And so there's two green T shaped connectors do I have to connect both to the 2 T shaped black ones ? Sorry for all the questions I've only had fords and Toyotas never a car let alone a subaru

So I did as it told me to, said itd be like one long flash than one short , mine just kept flashing no long no short ,just flashing until I turned off the key , unplugged the wire and turned the key on and it was solid so it's not like it always flashes. Maybe I'm doing something wrong or ?

It seems like if the connectors were never used then the original factory tape is still on there that needs to be cut back to get the wires accessible. The other black is probably just trapped in there somewhere.

 

Is the timing belt broken per chance? I can't remember if that will cause no spark but obviously it definitely will cause no start.

yes, a broken belt will cause a "no spark" situation. Timing belt would have been my first suggestion - before sensors.

 

timing belt turns cam sprocket which triggers cam sensor (drivers side) - if the cam sprocket isnt turning, the cam sensor has no input, thus no spark.

 

as for the 2nd black connector, it is up in there, just need to peel back more tape - on my 90, one was quite short and kind of a pain to get to.

If the belt did break than it would sound weird when cranking over as well as if its spinning faster since the will be no compression with the valves not moving.

 

There is not neccisarilly any reason to suspect the belt yet anyway, timing belts fail just a frequently as sensors.

Right on it may very well not be the timing belt it's just something easy to check that can break if left go too long and will cause no start. It's not either of the two visible belts, those are the power steering / alt and a/c belts (if it has a/c), you'd have to remove the small cover sort of near the coolant overflow to check it (unless of course the timing covers are already missing/removed/broken/not put back on previously).

sorry for late reply, was busy with work and all that good stuff, so as i stated above all the belts are good, today i went to the junk yard and got a CAM sensor and replaced mine, still just cranks, no start nothing, i have not messed with the diagnosis connectors yet. Just from experience what else could it be? I'm getting no spark, just cranks, could it possibly be the ignition crank or ignition ignitor ? not sure if you can test those, thanks again.

It seems to crank normal doesnt sound fast. So I found the two black connectors and connected them turned the key on, nothing, check engine light just continue's to flash, not like a long than short flash but just constant flashing, so does that mean that nothing is triggering the CEL??

Whenever you have an ignition problem the first step is to make sure power is getting to it. Make sure the fusible links are good along with the fuses under the hood and the dash. Then make sure power is getting to the ignition system. Purchase a factory service manual for the car off of Ebay. The best source of information you can have for the car. Since it is an older car you will need it for various things as they come up. Also purchase a digital voltmeter and learn how to use it if you don't already know how. Another vital piece of equipment.

 

You will really like how the Soob drives, especially in the snow.

so went to junk yard replaced the ignition module for like $10, tested the ignition coil, it was good to go, what else is there to check? I haven't checked the crank sensor yet because it is snowing pretty good outside. I have checked all I can think and that you guys have mentioned, my hopes for this car is almost next to none.
