My 2004 hyundia Santa fe won't start it just die out a code came up 0335 changed crankshaft sensor still won't start changed camshaft sensor won't start changed ecu same thing there is no spark to spark...

Check fuses under the hood. When the crankshaft sensor shorts, it often blows this fuse. It is a 10 amp fuse. I don't remember what number it is off hand but it will be efi related.

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...

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.
