Started my 2007 F430 last Sunday and blinking check engine light came on (I have cat-less headers so I’m used to check engine light). Car sounded different and felt sluggish while driving and didn’t build up power so we determined cylinder #3 had misfire. We changed all plugs and coil pack and car ran fine for 15-30 minutes, and afterwards lost fuel pressure to entire bank of cylinders on right side (same side as original issue with cylinder #3). Fuel pump is getting power. Help??!
