Question
We replaced the fuel pump , i.c.mod worked fine for a couple of days then it just died again. Have fuel at the schrader valve, partial start but wont stay running. ??????

Answer
You haven't given me much to work with, like engine. The TFI module could be your problem, these will sometimes fail in the RUN circuit and create the problem you describe. Did you lose fuel pressure so replaced the pump, or just guess at it? Do you have spark? Fuel pressure should be 35-45psi.
