So loooooong story short, my jeep died suddenly in the garage and refused to crank up ever again. Turns over but no sparks. Engine light is on and the code is P0340. I replaced the camshaft and crankshaft position sensors and went thru all of the wiring to the PCM with a multimeter and WD-40. Still nothing. I got fed up and got it towed to the stealership nearby to have them do their magic. They called back and said it's my timing belt that's worn all to hell and if I pay them a small fortune of $580 they will fix it for me.
My question is how hard is it to replace a timing belt along with the tensioner? I'm also worried about having a belt valve... I really dont feel like spending all of my xmas vacation money on this damn thing when ive already spent so much trying to figure it out myself.
