I remember driving a '77 straight-6 250 CI Chevy Nova as a kid on about a 13 hour/700 mile trip. It started having problems and loss of power up hills and I limped up an exit in the middle of nowhere on I-80 across PA and found an auto repair place at like 1AM. I parked there in the lot and slept in the back bench seat until the next day. I knew I had air, I knew I had spark as I tested for that... Next day the place opens and I wake up from the back seat out from under my blanket (ALWAYS KEPT A BLANKET IN ANY CAR ON ANY LONG TRIP) and the mechanic I walked up to said the same thing... AIR, SPARK, FUEL. He said ya got spark and air but no fuel. He found a tiny clogged fuel filter in the old 2 barrel carb I think it was in that thing. I think he charged me $5 to find the problem and change out that tiny filter. That was just good people taking care of good people I say. Lotsa good people here on this forum too.

Pizza and Graphite are right... Buy a new RCM and plug that in and see if the problem is fixed. If not, you are gonna want to keep a new RCM in the car all the time anyway as most do. I also keep a spare crankshaft position sensor and a spare camshaft position sensor around. I'd put those 2 in the in the car for any long trip to have them on hand in case of a breakdown where I don't have all my tools and it could take a shop a few days to get one in if that's the problem.
