1993 gt legacy ignition pulse problem

Hi i have just finished re-installing the motor in my 93 GT turbo legacy (single turbo) It wont start due to only reciving two spark pulses to the ignitor. Wiring diagrams ive got show there should be four? I am a electrican and ive traced back to the ecu and they are not coming out from there. I just had the drivers in the ecu tested at the local auto shop and they said they were all working. If the crank and/or cam sensors are working why would i have two spark pulses?? Your help is most welcome.

try you map sensor or your throtle pos sens. your fuel pump is designed to run all the time. it is suppose to run through the fuel rail and back to the tank in a constant cycle.

Check The Vehicle Speed Sensors.

The Legacy has 2 Vehicle Speed Sensors (VSS): VSS1 is located inside of the transaxle; VSS2 is located in the combination meter assembly.

VSS1

  1. Disconnect the electrical harness from the transaxle.
  2. Connect an ohmmeter across the transaxle's electrical harness terminals 9 and 16.
  3. The resistance should be 450-650 ohms.
  4. After testing, reconnect the electrical harness.
VSS2
  1. Remove the instrument cluster from the instrument panel.
  2. Disconnect the electrical connectors and the speedometer cable from the instrument cluster.
  3. Connect an ohmmeter or continuity tester across the combination meter terminals 7 and 11.
  4. Insert a small screwdriver in the speedometer cable drive socket.
  5. Rotate the speedometer drive and note the continuity across the VSS terminal. Continuity should turn ON/OFF 4 times per speedometer drive revolution.

Have you checked the ignition fuses, or checked for power to your ignition module? You have everything else covered! I hope these ideas will get you running. Best wishes.

We have a Subaru Legacy GT, Twin Turbo 93, the car cut out and will not start, no fault codes, replaced spark plugs, fuel filter, checked the fuel pump, replaced air flow meter, engine temperature sensor,...


sounds like your timing may be off, or have a crank shaft postion sensor failing, when it cuts are you losing spark completely? do you have a fuel pressue gauge? whats the pressure? also you could try running it with the map sensor unplugged and see if the condition improves

hi the first turbo is located on the drivers side of the motor, you will have to pull of the intercooler and some sheilds to get at it but it is managable if you have the patience and its also a common problem

Just wondering if it possible to make the twin turbos on a 2002 legacy gt work at the same time like a single turbo instead of converting it to single turbo


The turbos are two different types.One is designed to start a bit lower in the revs and the other to come in when the revs are higher.Its called compounding boost.It can be changed but to put it on a sinlgle turbo would cost a fair bit.If you hot up the ones you have by recalibrating them and exhaust,you do get VERY big gains.The car is more driveable and you can get big boosts in power if the tuner knows what he is doing.Some really big horsepower units come from triple compounding turbos and the torque levels are extremely high.Hope this helps

93 Subaru legacy 2.2 turbo 5 speed manual tries to quit, jerks, acts like its not getting enough air, running rich,check engine light has been on since Ive had it.Hesitation. unplugged oxygen censor and it...


Sounds like the timing is lost, go get your engine timed, change plugs and check the continuity on the spark plug cables, also have it scanned for errors on the sensors, that should lead you straigh to the real issue, hope this helps ;-)

Accelerator problems


Hi,

If you have the turbo charged version, this issue refers to the "turbo dead zone" between 3500-4000 RPM. This refers to the no acceleration between these two RPMs and is caused by the time difference between the time the second turbo kicks in after the first turbo has activated. If you are referring to acceleration loss/delay below 3500 RPM, the issue is "turbo lag" which pertains to the delay in time between the stepping on the gas pedal and the 1st turbo activating.

In some other instances including non-turbo versions, the problem may be due to air leak in the intake manifold and the air cleaner. In the turbo versions, it would include the in/out junction of the blower including the clamps.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
