I have got a S/C 2000 GT. Some days it starts just fine, fires right up, and some times i'll go to fire it up and it just cranks. I usally know when its not going to start becasue the fuel pressure gauge just start jumping around and you can hear the fuel pump tweaking out. Any ideas at all on what might be going on? Oh and the theft light usally starts to flash also.

I'd check the wiring at the relay/fuse box. Normally when FP's go out they just stop working and don't intermittently work. It has to be an electrical wiring issue.

I just thought I'd add, if you've had a tune lately check to see if your ECU is fully plugged in and still grounded correctly.

Havent had a tune, but the motor did come out for a rebuild. Not sure if that would have anything to do with it. But like I said it only happens every once in a while. On top of that the car likes to stall every now and then at stop lights too, and its an auto???
