Driving is all local. A mixture of highway and stop and go. As far as the failure being electrical, mechanical or impeded flow I don't know how to check for that. (H/E circuit?) there's no crimps in the hoses in or out of the pump.
No warning indication lights on the dash.
Could I be doing the install wrong?
I can replace parts but am lacking in the diagnostics area.
Woody would you like me to mail you the pump once I swap it out?
Thank you
