(G) Cam Belt Timing Problems

Hi All Im New To This Site And In Fact Fiats. I Have Justs Replaced The Head And Gasket On A 95 Punto 55s. I Have Set The Timing As Best As I Can See To Fiats Guide. The Car Now Will Not Start At All, It Through The Throttle Body And Comes To Tdc And Jams. Does Any One Know Of A Way To Check The Timing Without Using The Lower Timing Mark,or Have Any Advice That May Be Of Use
Thanks

Loads of help on here.

By the way its a really hard read when Every Word Stars With A Capital.

sorry about that had cap lock on oooops

Sounds like you might be 180degrees out on the bottom end.

what do you mean Comes To Tdc And Jams?
did you put the auxiliary belt pulley on correctly, it has a hole that lines up with a pin om crank pulley, if its not lined up car wont work

when i say it jams at tdc its as if the engine cant compress the mixture and stalls. once the starter is turned of the engine reverses slightly. i dont know if this will help but when cylinder 1 is at tdc the cam timing marks line up on the head. im realy stumped and in much neeed of help

oh forgot to mention engine turns over fine if i disconnect the injector

i have to say i realy dont know, is this to do with the rpm sensor that looks at the gaps on alternator pully

yep, its often put back in wrong place by people, its first thing i would check

thats great thank you i will try that and hope for rhe best

hi, sounds like the valve timing is out! there should be a spy hole in the top of the bellhousing under a plastic plug. remove this and turn the engine with a spanner until a mark on the flywheel lines up with the 0 degrees or tdc mark on the bellhousing. you are then at tdc, so check the cam pulley marks to see if they line up.
if they don't then you may have bent the valves! this might have happened because as the previous reply suggests, you may have put the pulley on wrong!

you dont get bent valves on a 8v fire engine

out of interest why did you change the head and was it new or used

hi all i changed the head due to a weired noise coming from the top end. a mechanic told me it was the head, after finding a spare head and fitting it i then found out it was the water pump bearings. any way i like to say a big thanks to binki. after removing the alternator drive pully and re fitting it the right way the car started 1st turn of the key. i would also like to thank all that have offered advice
thanks

what did the rabbit do
