Replacement Cam sensor made no difference.

 

Code reader still showing no codes, pending or faults. And it is still
reading rpm in live data when I crank.

 

I checked the MAF connection, it's clicking home securely.

 

I can feel the fuel pump relay kicking in and hear the pump run. When I
release the key from crank back to on, I can hear and feel relays under the
dash clicking, one straight away and one about a second or so later. I have
no idea what these relays are.

 

I'm really struggling to think of anything else to check. I don't have any
wiring diagrams and don't know the interconnections of the various relays
and Immobilizer modules into the ECU that might stop it firing the injectors
or spark otherwise I would try and check them to narrow down the issue.  

 

Let me know if anyone has any suggestions. I'm dreading the thought of
having to flat-bed the car to a dealer and them charge me a fortune to
diagnose the problem L

I've just checked the following:

 

Cams turn when cranking - they do

All fuses inside car - all good

All fuses under hood - all good

Main EGI relay - Seems ok, I can feel it clicking as I turn key to on

Main engine earth strap intact and good low resistance reading between
engine and chassis

With key on checked power to Cam sensor and coils - all good

Checked earth to cam sensor and coils - all good

 

Going to borrow a spare Cam sensor and fault code reader tonight and see if
that shows anything.

I'll do another check for broken wires and good earths etc. I was working on
the car whilst the battery was charging up. It had an aftermarket remote
central locking kit fitted that was not working (power locking via key was
still working). I traced the fault to a bad ground under the dash. The only
connection other that power and earth was a connection to the purple wire
input to the OEM power door lock module.  I have since completely removed
the aftermarket kit just in case but it has made no difference.

 

I also removed an aftermarket header and exhaust and replaced it with the
standard and had to disconnect the air box etc. to get access. I've gone
over these connections 2 or 3 times to see if they are all good.

 

I'll check the cams are turning tonight.

 

Thanks,

Rich

broken wires, loose connectors, non rotating cams? And recent
"improvements"? Always look where you last worked.

Apart from cam sensor, crank sensor and immobilizer are there any other
components feeding info to the ECU that might prevent it from firing the
injectors?

 

The first two look relatively easy to check, I've no idea how I would
troubleshoot an immobilizer issue?

 

Thanks,

Rich

You're not necessarily cutting *power* to the injectors-they are turned
on/off by switched ground from the ecu.

Battery charged up to 12.6V and cranked well so think that is OK. I will
check for cam belt today.

 

I'm just wondering what could cut power to the fuel injectors but still
allow the fuel pump to run?

 

Thanks,

Rich

Could be weak battery... but sounds like a classic broken timing belt. Can
you see the cam turning through the oil fill hole?

 

Probably not, but simple to check for.

Hi Folks,

I wonder if anyone can shed some light on my issue as I'm getting
nowhere at the moment. Car is a late 2001 and was running fine before
sitting for a week. Battery wasn't great and went flat, however, I
managed to get it back to full charge. Car cranks fine but refuses to
fire. After cranking, I pulled a plug and it was completely dry and
there is no spark when cranking with the plug against the cam cover.
However, I do hear the fuel pump run for about 0.5 seconds after I stop
cranking. I have no CEL and no fault codes logged. There is no key
warning light on to suggest immobiliser issue.

Can anyone suggest any possible causes? I'm going to borrow a crank and
cam sensor to see if they are causing issues as I read sometimes they
don't cause fault codes. But other than that, what else can I check? Can
someone point me in the right direction of some wiring diagrams for a
2001?

Thanks in advance,
Rich
