Hey Gang,
Need some pointers on what possibly could be causing this problem and where to start looking.
I have a SPF Daytona Coupe with Roush 427sr and Mass-Flo Throttle Body FI (fox based ecu).
On the way home from a long flawless drive yesterday the motor died 4 times in about 10 miles. All about the same interval from each event.
Here's what would happen:
- While driving the motor would die in an instant.
- The tach plumeted immediately
- No coughing...dead
- All electrical was still functioning
Each time I would hit the starter and the motor would fire back up. I would say it took more cranks than usual and stumbled upon start.
BUT ...
Then would run fine for a few miles until it happened again.
When I got home I started/stopped the car a bunch of times each of which it started fine.
Here's what I have checked:
- I can hear the electric fuel pump
- The fuel pressure regulator shows the set pressure
- No codes thrown from the ECU
- While running I fiddled with the key to see if vibration would kill the motor - nope
Any thoughts on what this could be and what to check?
Thanks in advance!
Jeff
