Is anyone good enough to work this out?

Hi,
I have a Galant with a 6A12 2lt. 6 cylinder engine.
It cranks but wont start.
It has only got spark to two cylinders (from the same coil pack)
I have tested the coil packs, leads and plugs. They're fine.
I have replaced the crank angle sensor.
I have replace the coolant temp sensor.
I have disconnected and removed the after market alarm.
It still cranks but still wont start.
Has anyone got any ideas of what to do next??

Try to get codes

But I say...
IFS...Ignition Failure Sensor

my fto did a very similar thing, cranked but wouldnt start and it was the ifs, like phil suggested. so I recommend that too

[phillbreeze]

Thanks Phill and Mark. I'll try that.....

..Is there a way to test the IFS?

[PHIL069]

You haven't just fitted this engine have you?

I'm looking for a IFS test procedure at the moment.

No, I havent just fitted the engine.. Thanks for taking the time

Here is some info.
If you can read wiring diagrams you should be able to work out if the IFS is getting the correct signals from the harness.
