Hello, I just want to make sure I understand. You vehicle cranks and won't start, and you have no spark. If this is the case the first area I wold check is the crankshaft sensor. This is the main sensor the DME will look at to start the ignition process and calculate timing. It is located in the front of the engine. You can check with a ohm meter it's resistance value should be 550 +/- 50 ohms. Take this measurment between pins 1 and 2 of the crankshaft sensor connector. You should also test for a short to the ground shielding between pins1 and 3, then 2 and 3, should be over 100k ohms.
