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.

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

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

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 ;-)
