I thought I had it fixed. I figured out how to bypass the security system by bending up a pin on each of those relays in the fuse box. I connected them to ground. The ECM and TSSM grounds those pins when the security is clear, which activates the coil in the relay and that closes the switches. One is for the starter and the other is for the fuel pump. It cranks and starts, but it won't stay running. The fuel pump runs, but never shuts off. I wonder if it isn't actually pumping any gas...

I can't see why it isn't working unless the ECM has another signal that does something else. I'll look at the pinouts and see if I can figure anything else out.
