I have a 2004 Volvo S80 with a 2.9 liter turbocharged engine. One day I shut it off, went in the store, and when I came out it wouldn't hardly start or run right. I had several misfires. I had a new fuel pump, spark plugs, and coil packs put in about a month before. Since then I have replaced the camshaft and crankshaft position sensors, computer, injectors, vacuum lines, and checked the compression. It still won't start. It will run for a second with starting fluid. I checked the oil trap too. It turns over good and tries to start. Any advice?
