  • [Corsa D 2006-2014] Not starting

    Hi all

    my daughters 2004 corsa 1.0 has been sluggish for a few days and lacked power when going up hills.

    went to start it last night and won't fire up.

    this morning I checked fuel as i thought possible blocked fuel filter but have have pressure at fuel rail.

    timing chain has been noisy for quite a while

    could it have slipped some cogs?

    any help appreciated

    It is possible that the chain has slipped but no way of telling for sure without inspecting the engine. There aren't many timing marks on them as you use a kit to set the timing, but there is a rough TDC mark for the crankshaft pulley. If you set the engine to that (or use a wooden dowel down No. 1 plug hole) then remove the camshaft cover and check the position of the lobes.

      thanks for the reply


      was also wondering could it be a faulty crankshaft sensor.


      do these tend to give much bother?


      is there an easy way to test?

        Crankshaft sensors are a common failure but if it fails then the ecu doesn't activate the fuel pump relay so no fuel pressure at the rail.

        Easy check. Turn the ignition on but don't crank the engine. The ecu will run a short priming run of the fuel pump relay to pressurize the system, check at the rail. Then crank the engine. If the fuel pump is activated there will pressure at the rail after cranking. If no pressure after cranking suspect throttle crank sensor.

          thanks again for the reply

          Stripped the engine to the timing chain this evening and discovered a broken spring at the bottom of the tensioner

          going to get a new chain and kit tomorrow and set timing

          is it better to go with genuine vauxhall parts

          any tips to follow when setting the timing or is all fairly straight forward?

          is it worth replacing the water pump at the same time? (all feels tight and no play on the shaft and no noise or leaks)

            Always use genuine parts for the timing chain. Give Anticancer a ring as their stuff is oem.

            You need a timing kit to set the timing right. The main bit is the tool to set the phase disc on the inlet cam.

            No need to replace the water pump if it seems OK, it's mounted on the timing cover so is relatively easy to do separately anyway.

            Hope it goes ok

            Check how far the cams may have slipped because they can't go more than a few degrees before you get valve contact with the pistons
