Hi
Ive checked the belt and all seems fine, the timing lines are still spot on aswell.
All the electrical connectors are sweet an connected correctly.
All hoses are attatched fine.
whats the best way to test the spark plug to see if they work correctly?

Firstly go through the starting procedure, then take a plug out. Is it wet or dry.
Dry suggests a fuelling issue, wet suggests an ignition issue.
To check plug, reattach it to the lead and lean it against the block, bottom end touching the block.
Get someone to turn the engine over while you watch for a spark at the plug.
It could be a crank sensor problem, so have a peek there too.

I've had somebody come and check it out for me, he plugged it into the diagnostics and found that the crank position sensor was faulty.
The mechanic reckons this is why the engine wont start. I'm going to replace this and get back in touch

Would that just automatically kill the engine if that failed? for what reasons would it stop the engine wanting to start?
Yes the CAS totally critical like forgetting to put the rotor arm back.
They are delicate like hens eggs, sensor fault no spark, no start

I am getting a spark from the plugs, when we remove the plugs they are petrolly maybe then this isnt the sensor thats at fault
Does not compute.
If you have fuel and you have a spark, it should start, unless the timing has jumped.
Any pops or bangs when trying to start?
Are you sure the camshaft is turning?

yes there is a spark and there is fuel but still no go, im going to try and see if the new sensor makes a difference in the morning, if not then im stuffed.

I'm going to fit the new sensor in the morning, is there a proper way to remove and refit the sensor, i can see it is tempting to fit a screw driver between the sensor and the flywheel but id rather do it properly to avoid any damage.

spray a load of wd40 onto it cos it sticks in with dirt. undo the 8mm bolt then twist the sensor around a little with some pliers and it should free up and come out.
if the crank sensor fails you will have no spark or fuel (but you will get a little fuel when you turn the key on. that is just a priming squirt

The weird thing is im still getting a spark, is it possible to still get a spark if the sensor has failed?
nope... im pretty sure them diagnostic things are pretty bad
i would make sure all the connections are good. like those to the fuel injector/s

Hmm im more worried now because the wires to the sensor are dodgy but it still sparks
worth replacing then. they are delicate things living in a harsh place. if you want to swap it for cheap go to a scrap yard and look for any fiat. 90% of them have the same sensor

Ok so the new crank position sensor is fitted and what a suprise it still wont start.
What else should i check
