I have a 1998 GT with no mods. I stored the car for the first time in 10 years over the winter ( in MASS ) and now I seem to have an intermittent problem. I started the car about once a week and it ran fine at idle all winter. There was roughly 1/2 tank of super in it this spring left over from the winter. First time this year (May) I drove to work and after about 30min the car started to sputter in parking lot when I pulled in. It died and would not restart. I did not hear the whine of the fuel pump pressurizing when I turned the key forward. Checked the Shrader valve and just got a dribble with key on. Left car overnight, called for a tow the next AM and it started right up. Had it brought to dealer - said FP was fine and sent me on my way with a $100 diagnostics fee. Said it was due to the additives in the winter gas and it was causing a possible vapor lock. Said to refill, add a bottle of FI cleaner and it should be ok. Took it out second time (June) and once again it started and drove fine - took it up to 90 without hesitation or roughness at all. About 30 minutes later I pulled off to get a soda and it started to sputter in the lot and died. Once again no pressure in the Shrader valve. Waited about 1 hour and it started up again and ran perfectly. Same issue - no fuel pump hum with key on initially but after 1 hour I heard it come on and I knew it would start and it did. Now I'm afraid to drive it cause I don't want to get stuck anywhere. Any chance this is at bad CCRM or would that not be an intermittent problem as I described. To me the FP sounds the same as it always did since I've owned the car - high pitch hum and not rough or louder than normal. I did notice a check engine light on now so I will look into that as well. Trying to diagnose this more closely without just random part swapping. I will also check for a bad ground as this seemed to be a concern in some threads. I appreciate any help. This car has 50,000 miles. Its had a fuel filter, wires, new battery this year, but original coil packs and plugs that are probably due to be replaced soon I imagine. Has run perfect since new without any issues. Thanks in advance. I'm missing my top down cruises this summer so I appreciate any help in getting back on the road.
