Question about 1991 Subaru Legacy

1 Answer

91 Subaru will not start

It is getting spark... compression is at 60-90 pounds...timing marks seem line up at spark and at top compression..

does not seem to be getting gas ... how do I check to see if the injectors are working?

    The compression gage was not seated. It is 150-160 psi. It also seems to be getting gas but the spark seems to be radical but strong. It sparks two or three times between compression spikes and rotation of timing mark on cam shaft pully.

    could it be the ECM? how do you test the ECM? crank shaft senser?
    cam shaft senser?


  • raynbarb Jan 16, 2009

    by radical I mean that there is spark 2-3 times in one rotation of the timing mark.

  • raynbarb Jan 16, 2009

    the #1 spark plug fires 2-3 times per revelution of timing mark mark on timing chain pully. How can I tell if the ECM module is working right?

    the belt is on like the book says but will not fire has spark but we did notice the crank sensor wheel has cutaway marks like it has been scraping on something and had cut about half the sensor marker off from the side

    next thing to check is the fuel pressure.

    What does radical but strong mean??

    compression 60-90 PSI? something is very wrong there.

Hi there have you tried sitting in car with doors shut turn ign on & listen for fuel pump priming up you will hear a buzzing noise for 5 secs then stops if you don't you will need to check wiring to see if there is power going to fuel pump & check earth wire might be black if you are getting power to these wires then its possible its the fuel pump if not you will need to inv it further (try fuses first).

Daihatsu Charade G102 91 Need to change thermostat though appears hose from top of radiator runs to housing and bolts are hidden under distributor assemble. Any step by step help would be appreciated


If you have to pull the distributor, take off the cap and mark on the dist. housing the position of the rotor, exactly where it is pointing to. Also mark the dist. housing relative to the engine block, or the adjusting bolt or nut, so when returned to its place in the block, the distributor is in the same exact position. Do not rotate the crankshaft with the distributor out, or you will have to re-time it.

To re-time the engine, you have to put the #1 cylinder at Top Dead Center of the compression stroke, then drop in the distributor with the rotor pointing to the #1 cylinder plug wire tower. Now it is in time at zero degrees. Get it running and warmed up, then use a timing light to set it at the BTDC specification.

To find the compression stroke of #1, pull the #1 spark plug and turn the engine clockwise with a socket on the crank pulley bolt. Hold your finger over the plug hole. When you feel pressure build up, you are on the compression stroke (there is an exhaust stroke and a compression stroke-when the piston is rising on the compression stroke, you will feel the pressure. There is no pressure build-up on the exhaust stroke.) As soon as you feel the pressure, look at the crank pulley and continue turning the engine clockwise until the notch or mark on the pulley is lined up with the zero degrees mark on the pointer scale. The #1 piston is now at top dead center. Now drop in the dist. with the rotor pointing to #1 spark plug tower. However if the engine was not disturbed while the dist. was out, you don't have to retime it if you marked both the rotor position, and the dist. housing relative to the block where it sits.

Iv been working on a Subaru that my friend started and couldn't get running so he called me he replaced a burnt valve in the head and re installed it got it back together and no start. i got there...


if its firing 180 out you need to make sure when you set the timing its on the compression . when the piston is at the very top of the stroke The first one is the Intake stroke, the piston moves down the cylinder while the intake valve is open. Once the piston reaches the bottom of the intake stroke the intake valve closes. The next stroke is the Compression stroke, during this stroke all valves are closed and the piston moves back to the top of the cylinder compressing the air fuel mixture. Once the piston reaches the top you are starting the ignition stroke. With the piston at the top the spark plug fires igniting the compressed air fuel mixture forcing the piston back to the bottom of the cylinder. Once it reaches the bottom you begin the Exhaust stroke. The exhaust valves opens allowing the piston to rotate back to the top pushing out the burnt gases.

After changing the idler bearing on my subaru legacy 91 wagon compression is low in the nr 1 and 2 cylinder the car wont start, timing was jumped as the bearing failed but appears to be correct as repaired


I assume that you mean the cambelt idler bearing.Ok if you are sure that the timing is correct for all cams(DOHC)?.Then the problem may be bent valves caused by the bearing collapse allowing the cams to go out of timing and cause valve strike.
I would recheck the timing,ensuring all marks line up precisely,the only one that should look 1/2 a tooth out is the crank.Genuine belts are always preferred for these as they have all the markings on the belt to align all the cams and crank,some other suppliers do not have this
I hope that this helps you,or get back to me with your findings.

I am having a hard time getting my 02 pt cruiser on its compression stroke when i line up all my timing marks what am i doing wrong?


NUMBER 1 PISTON TOP DEAD CENTER WITH DISTRIBUTOR ROTOR POINTING TO NUMBER 1 SPARK PLUG AND BOTH VALVES CLOSED.LOOKING AT TIMING SCALE CRANKSHAFT DAMPER TIMING MARK AT O.ON TIMING SCALE.REMOVE SPARK PLUG NUMBER 1 PLACE FINGER NEAR SPARK PLUG HOLE.WHEN YOU FEEL GUSH OF AIR ENGINE ENTERING COMPRESSION STROKE.SOME MECHANICS USES A SPECIAL WHISTLE WHEN PISTON GET TO COMPRESSION STROKE THE WHISTLE WILL BLOW TO LET YOU KNOW GOING TO COMPRESSION STROKE.

Replacing a timming belt where are the marks suspost to line up


You didn't get the timing marks lined up between the cam and the valves. You are going to have to open it back up and line the marks back up correctly. Make sure you get the Number 1 cylinder lined up to Top Dead Center on the compression stroke and have the valves lined up correctly then line the timing marks up on the timing gears.

I was driving on the freeway and my 1991 Plymouth Laser RS just died with no warnings. The starter spins and turns the crank but it just doesnt seem to have any spark. all I hear is a whizzing sound. It...


Doesn't seem to have spark?? did you use a tester?? basic needs, spark tester(in line works best) fuel pressure guage, injector signal tester(noid light) and finally compression guage, rad tester optional, check spark and injector signal, the remove spark plugs and note their color, do a compression test, all cylinders should read within 10 percent, lo compression on one or two indicate head gasket, no compression timing belt, have fun

I have a 91 300zx non turbo won't start


Are you sure the new belt didn't jump time? How was the belt tensioner when you replaced yhe belt? Did your water pump leak onto or into your crank sensor?Are you sure you have proper fuel pressure?When you replaced the timing belt, did you make sure to find top dead center on cylinder 1 ? Just lining up the timing marks may not have worked if this is indeed what you did.If you had the crankshaft rotated 180 degrees, your motor would be trying to fire on the exhaust stroke, instead of the compression stroke. To find T.D.C. disconnect your battery,rotate your crankshaft until the piston that is marked #1 in your firing order is at the top of its stroke, this can be accomplished by carefully inserting a wooden or plastic dowel into the sparkplug hole of cylinder#1. The dowel will rise with the piston and at the point where it starts to fall will be T.D.C. Now your timing marks should line up,and you will then be on the compression stroke. good luck! hope this helps
