So I replaced the TPS on my 94 4.0 and accidentally left the ignition on for about 30 minutes and heard a loud clicking coming from the relay box by the battery. Now I have no CEL or buzzing when key turned on, no fuel pump and no spark can I assume the ECM was ruined.jumping across the fuel relay runs the fuel pump, swapping relays doesn’t work. Prior to the whole ignition debacle, the vehicle wouldn’t start if it was less than 35 deg F, above 35 fired right up ran like a champ so in trying to fix that I have replaced: Cm sensor, crank sensor ,TPS, dist cap and wires, O2 sensor, plugs, rotor, and both temp sending units.
