I recently swapped out the engine in my 1.6l fusion. After swap, engine was hard to start, then started for 20mins, sounds great took it on a drive about 10mins in the engine stated to cut out with cylinder 1 miss fire and low fuel pressure codes. Then all went away and I was back to driving normal. Drove it home and parked it. Next day started right up, drove it for about 5 min and the engine started stumbling and shut off. I have not been able to get it started since. Code at the time was 02 bank 1 rich and low fuel. Now all I get is crank no start and no codes.
New engine came with just about everything. The only thing from the old engine I used was the computer and harnesses.
