Car spun the serpentine belt because of a faulty tensioner, after replacing belt and tensioner tried to start car and would not fire. Got a 300 code for a misefire and a P1371 code (#1 cylinder firing early). Further investigation shows the crank shaft pulley slid back (separated) about 1/4". Timing belt is intact but cam shaft pulleys don't line up at 11 and 1 when crank is at TDC, is it possible that the timing belt jumped?

hi from uk to retime cambelt is as follows = the crank cog has a mark which lines up with corresponding mark on front of engine block mark is approx 12-30 o/clock this is TDC No 1 the the cam cog has a small drilled hole in one of the webs just below the cog teeth ? this hole has to be at 12-o/clock position and then using a small mirror if you look through this hole you will see a vertical notch on the front of block this is theTDC mark for cam you then fit belt anticlockwise from c/shaft to cam then round tensioner then release tensionor to tension belt and then lock it up torque both bolts 20 - 27Nm rotate engine manually 4 complete turns clockwise then recheck marks ok /re align ? then re assemble crank pully bolt torque is 140 -150 Nm may i just inform you? that your engine is what is known as interferance that is to say in event of c/belt failure there is more than likely valves to piston contact however this can also occure too if miss timed belt fitted and engine has tried to start ? a compression test on cylinders will confirm if this has happened or not ? hope this helps
