I've got a 94 FJZ that died last weekend. Just shut down like someone turned the key off, no start up and no CEL light. After reading up the FSM and on MUD I went through all the EFI components and they all check out fine, relays, fuses, resistors, etc. Fuel pump runs when hot wired at the diag. port. There's power to the all the fuses, relays, etc. The ECM has power at all the right places from ignition switches and the ECM ground works too. Also, the cel light comes on when hot wired as per FSM. So anything else that could cause the cel light not to come on besides the ECM being bad? I'm totally stuck. Anyone up here around the Santa Fe area that might be willing to let me try their the ECM on my truck? Any help would be greatly appreciated, thanks.
