My Peugeot 106 1.0L from 95 won't start after head gasket replacement(it cranks)

[Paulo Ribeiro]

Hello all,

A week ago I noticed one of the cylinders was down in compression and before it got worse I decided to change the head gasket to see if it would bump the compression up. A week later the job is done but the car won’t start. At this point I can’t figure it out. Some of the possible causes;

– Fuel not getting there: I can cleary the fuel being pumped by the carburetor to the intake manifold. When I remove a spark plug sometimes and can see some smoke also so I suppose the fuel is getting there;

– Air not getting there: I think this isnt even a problem, the system is so simple I’m sure it has air enough;

– Damaged spark plugs: I changed them weeks before this and I can clearly see the spark in all 4 of them when testing them;

– Head gasket poorly replaced: I have check the compression on all cylinders and they are all very close to 120 psi, so I think the replacement was successful (I know I should just checked this with the engine hot and after a few kilometers but the car wont start);

– Timing belt out of time: I’m confident that it is on time, when doing the job I blocked the flywheel. When double checking after not starting both the flywheel and cam shaft are in the right positions. For this car model, from what I read, it has to align the flywheel hole and the cam shaft hole.

At this point I’m out of ideas. I’m confident that I plugged all the eletrical wire back too, if not which cables can stop me from starting the car? I read something about the crank shaft sensor but I think this model doesnt even has one.

I hope that someone can help me with this as it is my only car and I need it for work.

Let me add that before this I never had problem about the car not starting. And I have fuel in the tank 🙂
