The other day I took my son out for a 1/2 hour drive. Everything was fine. On the home stretch I decided to piss off some golfers so I gunned it pretty hard
. The engine cut out 3 times. Not your typical hesitation, but on-off-on-off-on-off. Absolute silence between these split second 'offs'. Then it was fine, golfers pissed, mission accomplished
.
Then yesterday I warm her up for 5 minutes, drive up to a stop light, press the clutch and the car dies. Crank it and nothing. Switched on and off the fuel pump switch a couple times like some WWII Ace about to crash land. I limp to the side of the road. Won't start. Engine looks good, still cold. I crank it again and viola! No problem for the 60 mile round trip.
My confidence is waning. I have a 5 year old Roush 402R/SPF. The installer took out the mechanical fuel pump and I can't find the electrical one. I presume it's by the tank. All I see is a braided line going from the carb and down through the tunnel.
My neighbor thinks it's the ignition, MSD/Fireball. Pump makes quite a loud noise when ignition is on. When I start, I usually turn the key on, let the pump work for a few secs, pump the gas and start. The installer also took off the choke for what that's worth.
Any ideas? Could fuel boil while engine is cold? Loose ground? How many ground connections are there?
