My 87 260 249K was running like a champ. I parked one night and the next morning she started but made it less than a mile before she had no power and died. It was rough starting but would run until I put it in gear and then would stall. Now no start at all.

Will not fire on a few shots of starting fluid

I changed the fuel filter, fuel pump relay and OVP.

I have fuel at the injectors, replaced screen in fuel dist. Removed and cleaned fuel dist. When I hold down the air plate and engine is cranked if I crack an injector there is great fuel volume.

Wires, cap and rotor have less than 5k on them. I removed the cap and it looks fine. Plugs have maybe 15K but look OK

I have a weak yellow spark when grounding a plug to the manifold.

So I have fuel, air, and some spark - Coil? CPS?

Any suggestions appreciated.
