I had this same problem on my 2000 s10. after alot of trouble shooting I foun that I had inadvertanly broken the ground wire connection located inside of the frame (driver side by the rear bumper. The wireing sheath prevented seeing it but ohming it ot told me it was open ground due to infanant resistance from pump connector to chassis. hope this helps.
