99 blaz code 300,1345, 341
Im getting code 300 mult misfire and 1345 cam to crank position correlation fault as well as 341 cam sansorcircuit range / performance. I think it is my CMP sensor but what are the odds of my timing chain being off. I don't hear major noise but it won't start and chugs when it tries to run. I feel compression when I turn it over by hand. Any Suggestions 99 blazer with a 4.3 113k miles. Well it wasn't the CMP sensor or the CKP sensor. I just took off the timing chain cover and the marks seem to line up like they are supposed to on TDC #4 compression. Any ideas?
