Question about 2006 Fiat X1/9

No spark after cam sensor replaced - Frustrated!

OK so we've had a bit of a nightmare recently with our 20v turbo coupe. It was close to 70k miles so being cautious, we decided to get the timing belt done (so as to avoid further damage to the engine if the belt broke while driving).
As you know, major job, so we also replaced the clutch at same time and after big payout for the labour, thought it was better than ever.
It drove for 2 days before letting us down. went to start it and it just wouldn't start.
It was hooked up to the computer and only problem that came up was the cam sensor.
Another engine out job, but had to be done.
Brand new sensor was fitted (had to be sent from Italy thru UK, to Ireland). The mechanic said they test drove it twice afterwards and it was fine. We went to pick it up and it wouldn't spark again. Exact same problems as before sensor was fitted.
Anyone had this happen to them before? Any ideas what the problem could be?
We're so frustrated, as the car was better before we spent all the money on it - should've left it alone!!!
(Spent about 3k on it now and hoping we won't have to spend much more)
Any advice much appreciated.

Hi ,bought a fuel injector from eBay and I'm not sure it's the right one for my fiat coupe 20 v turbo ,are the injectors for a fiat coupe 20v non turbo the same ?

Turbo and non turbo are not the same...check the serial numbers against one another, if you install one wrong injector you will damage your engine completely!
ask the agents nicely if they can compare before replacement! Good luck cheers Dave

So... I'm starting to get just a bit frustrated... after installing the new PCM, my dodge avenger, 96 2.0L ran for 5 days then went out again, fuel pump works and I've got spark but no start..

after all that work its terrible that something else goes bad however since you do get spark and fuel i would say crank or cam sensor but then if one of those goes bad it wont allow engine to turn over and would shut fuel pump off. so there is only one thing left to cause it you have a short in the harness somewhere maybe just a lose connection on the cam or crank sensor put dieelectric grease in all your connectors

2003 Pontiac Vibe - 4 Cyl. 150k miles. Ignition coils keep going bad - every 4-6k miles. Coil 1 has been replaced 4 times, Coil 3 once. Coil 4 twice in the past year (20k miles). All spark plugs

Install new spark plugs, 4 new coils & replace the oxygen sensors

O2 Sensors are only good for 100,000 miles, then slow
down or quite

No idea why the coils do not last 5 or 6 years

Cylinder #1 is always at the front on a 4 cyl

Go to Rock Auto --Buy Wells Coils,NGK Double
Platinum Plugs & NTK O2 Sensor

Those parts are expensive because you have a Totota
Motor I guess

3rd turbocharger

on most occasions its the cooling system for them thats at fault, try upgrading the oil coolant rad for the turbo, it might be a bit expencive to start but will probly save you keeping on buying housing for your turbo, or check make sure you do not have a blockage in the oil cooling system, hope this helps

I used cam locks and belieseems that my crank sensor is not working now so I would like to know how to double check my timing marks before I close it up again. Can you help?ve I followed all the...

You should be able to remove the upper front forward cam-dust covers. With these out you should be able to align the cams to their timing marks. As for the crank you'll have to rely on the timing mark on the forward crank pulley/harmonic balancer.
I hope this may have assited you. If you in need of further info or images please send a note back.
Best regards,
