My ecm1 fuse keeps blowing. The car will not start. What should I do?
Check the Powertrain relay first. Trace wiring from relay yo fuse and from fuse to the ECM and look for a short. If it checks out you may need to replace the ECM. The wiring diagram below shows the ECM 1 Fuse and wiring. It connects to the ECM from there.
