I have a 92 2.0 vr4 with a junkyard engine i swapped into it. It has run great for 600 miles. One morning it started rough and idled terribly but still drove to work without dying, after work it killed multiple times on the way home untill suddenly it lost all power and died.
Now... it does crank, and pops once. nothing after that.
I tested spark and i have intermittent spark on cylinders 1 and 4 but 2 and 3 are dead. I ohmed out the ignitor and it was bad, so i replace it. same issue remains. I have pulled the ecu and checked the caps, all have been replaced already by the previous owner. I since then plugged in a spare set of coil packs and had the same exact problem, int. spark on 1 and 4 but nothing on 2 and 3. I have also swapped the cam/crank sensor on the head with the one off of my old motor, (no guarantee this is a good one either, but i dont know how to test it)
Has anyone had this issue to help me speed this up? im going to retest my coilpacks, new ignitor, wires to the crank sensor etc this weekend.
thanks for any info.
