Backfire thru intake after new timing chain installed
I have a 2001 Silverado with the 4.3 Liter V6.
I replaced all new Timing chain and sprockets. After putting everything back together it would not crank without holding gas pedal down and would not idle at all. It gave me a P1345 code CKP/CMP CORRELATION CODE. So i got the number 1 plug TDC and the rotor button was not on the 6. So i pulled the distributur and lined the button on the 6. When i started it again it backfired through the intake and now will not start at all. I checked the number 1 plug position again and now it will not line back up with the 6 on the distributor. I am stumped. Please help. |

Re: Backfire thru intake after new timing chain installed
This is a typical engine response to incorrect cam timing and/or ignition timing.

Re: Backfire thru intake after new timing chain installed
timing chain installed wrong. give details on how you took apart the front cover old timing chain.. rotated the engine .. distributor removed when and why ?
may have to take valve cover off so you know if your at TDC and the cam/crank are setup properly.. why did you do this work ? how many miles on engine . |
