just bought my truck a month ago 2000 5 speed 4x4. turn on the key wait for light to go out go to start and nothing. leave clutch in and key in start position somtimes it takes 25 seconds other times i have to cycle it a few times to get it to crank over. when it cranks over it always starts easy. when i got the truck dealer told me they had to replace the fusible link? can sombody point me in the right direction.
