Ok its a 94 supra 6-speed TT, single turbo. Motor took poop, put in aristo or soarer motor. Now it wont start. When cranking the car fires and starts for a split second but the shuts down. The fuel looks good and I would think there is spark is its initially starting fine. Have swapped a few parts out with running supra; so far swapped, injector resistor box, ignitor box, maf sensor, map sensor. Only other thing different is that the crank position sensor is not the on that was on the motor as it was broken. The reluctor gears look the same for the most part. Might be a tad but different hard to tell while on the motor. We unhooked this sensor and then it did not fire at all, so I would think its working. Are the reluctor rings different on jdm motors maybe? We also swapped the ecu with a working 98 unit and car did the same thing. Any help is greatly appreciated, please dont make fun of thee run on sentences. thanks.
