R u trying to say reverse the firing order which is 3421? So 1243 is what you recommend ? i have no reading on rev counter when trying to start car ! Points towards crank sensor not reading flywheel ! Quote Link to comment Share on other sites More sharing options...
LR5V Posted March 15, 2020 Report Share Posted March 15, 2020 Was it running before the timing belt change? it Seems odd that the crank sensor to wait till now to fail - checked the connector is plugged in properly? How did you do the timing belt? You knew to turn the engine over twice to check the timing, if you were a tooth or even a couple of teeth out the engine would run, but not well. Assuming it’s a 16v did you use a proper tool to lock the cams for the small belt? Did you mark the old belt and factory marks and copy them to the new belt counting teeth?
