Crank position sensor question

[bheston]

Working on a family member's car, she reports that it often starts then dies, then she starts it a second time and runs fine. I found two codes, P0335 and P0327. P0327 is knock sensor low voltage and P0335 is crank position sensor. I've heard of the crank sensor causing hard starts before, and if that sensor is bad it could cause engine knock right? I'm going to do some more testing before buying any parts, but my main question is, does the P0335 code refer to a problem with the 7x sensor in the block or the 24x sensor behind the balancer pulley? Thanks guys!

if the knock sensor is bad this could cause the timing to be retarded so much you get a poor cold start. check connections replace.

crank sensor I found acts up when it gets hot. being what it is it could also fail when cold just as much. if its not working the vehicle will not run...........
