Trouble starting

[FOT Fast]

I'm having serious difficulty starting the Tuscan after I replaced the finger followers and cams. Everything appears to be ok as it turns over but it just won't fire up. I've attached the diagnostics to the ecu and I'm getting no fault codes. One strange thing is that one of the Lamda sensors was unplugged and it didn't flag that as a fault.....

I've also started to get a rapid clicking sound from the engine. At first I was concerned that a valve was sticking but I've had the cam cover off and it's happening faster than the engine is turning over so it can't be that.

Any ideas?

Hi J,

Yep, got good compression although I noticed it is slightly down on cylinders 2 and 3. I was really worried that I'd balls up the timing but it doesn't make the clicking noise every time.

So I've just taken the spark plugs out and held them against the engine whilst turning it over and there is no spark at the plugs.Checked the fuse and it's fine. Does anyone know what the wires to coil pack should output? Otherwise, I assume the coil pack has died. Although, I would like to check the loom out before buying a new coil pack.

Thanks all. I did have the engine out and it has been out for a long time. I initially got it started but it sounded awful and wouldn't run properly and now it just won't start at all.

So I removed the wiring earth from the bellhousing and ran a wire direct to the chassis and used a pair of jump start cables to run an earth from the battery to the chassis and engine and it made no difference. Since, putting the engine back in I've already had to replace the immobiliser and the dalis key receptacle.

The dash has shown a few diagnostic codes mainly e and o. When I plugged the ecu software in everything seems normal.

I'm going check the crank sensor and if that's ok it's got to be the coil pack hasn't it?

Can someone confirm that Pin 4 on the Coil pack connector should actually go to Fuse 17 on the fuseboard?

I think that's what the Orange Bible is telling me.....

So it goes pin 4(red wire)coil pack -> ee on Bulkhead mil connector -> Fuse 17

If that's correct then it's not the coil pack and I've got a fuseboard problem as I have continuity between ee and pin 4.

Just thought I'd post an update after I finally got around to fixing the Tuscan, it was the crank sensor gap not being large enough. I placed a thicker washer under the crank sensor and now it fires up ok. Thanks for all advice and offers of help.

Now I've just got to get to the bottom of all the rest of the electrical gremlins....
