I was hoping to get some diagnostic help. Around Christmas my 2000 gt was riding a little rough and felt like it was missing a bit. I got a bit of gas and it seemed to get worse- thinking it was bad gas or something I filled up and added seaform to the tank and limped home. I parked it for 4 days over Christmas and when I tried to start it, it wouldn't start. Just made a real odd noise.. thinkkng it may be the fuel pump, I primed it by turning the key part way a few times, it was better but still no start. Attached jumper cables and got it started. My usual car guy isn't avail, but I sent him a vid and he thinks it's the coil pack. In doing some reading I saw it's also possible that it's a bad EGR. By this brief description, any opinions?
