So I did a 5 speed swap about a year ago and the car was running fine but I was due for emissions and I had to get a different ECU since the one I had been using was the stock A/T ECU and I needed the M/T ECU in order to pass. So I got one pulled from another 98 and I swapped it, it plugged in a everything fit but now the car will not start. It cranks but wont start. Any ideas on what could be going wrong? I dont want to automatically assume that I bought a non working ECU. thanks
