172 wont start

[Johnson.]

Hello,

I have done a search on the problem to no avail.

I have recently purchased a 2003 Clio 172 under the impression the cambelt had snapped. On further inspection, one of the idlers had given up the ghost and caused the cambelt to slip. We have fitted a gates power grip kit using the correct tools so i am confident we have timed the car back up correctly.

After putting the car back together today, the car is turning over but not firing. The car appears to have a good spark and is receiving fuel.

Does anybody have any ideas or suggestions ?

Cheers,

Ben

All valves are fine and moving freely.

done a leakdown test?

Oil down the spark plug hole ?

nope, pressurizes the cylinder and shows up any leaks. you can do compression test as chances are valves bent so would show up easy enough.

Got ya. Not done since the cambelt was changed. Prior to the cambelt being changed, no compression was registered on the tester in any of the cylinders, we put that down to the timing being out! Either that or a dodgy tester which seems unlikely given that its practically brand new.

you will have bent valves on it.

Had another play this morning and the car is firing.
