Roush 427R engine issue. Troubleshooting..

[WardL]

What Roush engine number is this? Right on the valve cover there might be a 427R - XXX. The XXX is the engine number. What number is it?

I would sugguest you start with the easiest and cheapest things first. Battery connections, Chassis ground at battery, Power and ground connections at ignition box. If all these items are good, check the charging system. (Contact me if you need info how to do it) Then I would have the battery load tested (free at auto parts shop) and lastly the Ignition Switch.
So many problems like this are loose wiring, or a bad battery or cable.

Sounds like vapor lock. Maybe a fuel line is too close to something hot...

Not sure on the engine #. The car is in the shop. It is somewherein the mid 700s. Vapor lock sounds like it could be it.. Whats the fix? Different fuel pump??

I agree with Blas ...start simple then eliminate. I had a similar issue in two seperate circumstances. First was a loose battery cable (if you car has a cutoff switch check those connections too). The second was a failed coil wire...it looked fine until i pulled the terminial...and it was completely off the wire.
