Put a new 22HP Subaru into my 98 ARGO Vanguard today.....all was well until I fired it up for the first time. I seemed to have switched the power wire on the relay and as soon as I turned the key to the on position I heard a sizzle noise and saw a big puff of white smoke come out from under the engine couling near the fuel pump.....I took the couling off but could not find any burnt wires or melted parts??

I reconnected all the wires properly and the engine turns over, starts, but only runs for a second or two and then dies.

Any ideas what could of fried, and is this why my engine will not run now??

Your help is much appreciated.
