ecu fuse blew and was informed to change the fuel pump truck wouldnt start without a new fuse,but when i run it over 60 the truck boggs down getting ready to stall? any help? on what it could be?...thanks harry
It may help to tell what engine size????? So......did you replace the pump? Whats the fuel pressure? Did you replace the filter? Maybe the pump, but its all guesses with out you telling us the whole story. If the pump is blowing fuses, thats your first clue, Replace it.

My Hyundai Santa Fe 2004 doesn't shift down from overdrive when driving at 70 mph. Recently replaced the crankshaft sensor and timing belt. It is an automatic and the other gears seem to shift alright. When excelerating to pass a car the engine light came on and then went off once the mph levelled out. Why does it seem to stay in overdrive at high speeds?
