engine electrical
#1
I have a 1997 Mercury Sable and have had problems with the engine electrical. The engine stalls and fails to restart. I have changed the Power Module located by the battery, checked the crankshaft position sensor, however the engine keeps stalling. The mechanic does not have a diagnostic computer to scan the system. Should I have it ckecked with the computer?

sounds like the fuel pump relay going out or could also be the Idle Air Control valve gunked up. i would pull off the air filter tube and open the throttle butterfly and see how much gunk is in there. the idle air control valve is held on by 2 5/16 bolts. lots of times the piston/valve in there gets gunked and doesnt work righ. cleaning the builup helps lots.
