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 Rich From: Bell, Richard (GE Energy Services) Sent: 10 March 2011 18:02 To: '[email protected]' Subject: RE: Non-starting 2001 help needed 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.

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.

And recent "improvements"? Always look where you last worked. _____ From: Bell, Richard (GE Energy Services) [mailto:[email protected]] Sent: Thu 3/10/2011 8:09 AM To: Bill Cardell; Ken Bogart; [email protected] Subject: RE: Non-starting 2001 help needed 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?

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?

Can you see the cam turning through the oil fill hole? Probably not, but simple to check for.

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?
