The engine will start with the key in crank position but the second you let the return to run the engine shuts off. With key in the run position the gauges won't work.

Hi,

I attached a pic below of the ignition switch wiring schematic. Note that power for the engine to continue running in the run position goes through ignition fuse 0 in the left instrument panel fuse box.

Do me a favor. Check that fuse. First, confirm the fuse is good. Then, with the key in the run position, see if it has power to it.

Here is a link you may find helpful:

Let me know what you find.

Take care,

Joe
