3200 turns over, starts for fraction of a second then dies.

Oh I remembered one other thing. When my relays played up they popped up a fuel pump/pressure code on the ecu.

What's the warning lamp that continues to flash on the dash, they should all stop flashing and be steady or go out..??

 

[karatemaserati]

the CEL light?? that always normaly comes on when you turn the ignition and goees out when it starts doesnt it.

At 12 seconds on the first video, the NO/ASR error light flashes up as the engine cuts.

 

[karatemaserati]

yes con you are right im just about to upload a better vid of this and some more of the fuel rail vids and T-body vid

 

[karatemaserati]

more fuel right rail

i love your lumo green pen by the way it almost matches the backlight

Do you have a code reader? If so, could you have a look to see if there are any errors?

 

[karatemaserati]

no i havnt, going back to what you said erlier about relays, they are the little yellow boxes right in the boot or are they fuses? (my electrics is even worse than my mechanics) iv taken them out and tapped them as you said but no difference

 

[karatemaserati]

throttle body. THATS NOT MY VOICE BY THE WAY ha

Ok, I think you have adequate fuel pressure, my next issue is air. Can you take the Y pipe to the throttle body off and get someone to start it whilst you file the butterfly valve and see if its not working or starving the engine.

I still think the NO/ASR light flashing up at exactly the same time the engine cuts is a factor.

 

[conaero]

Ok, you beat me to it. You have fuel, you have air, all 8 coil packs and spark plugs are not going to fail so it would appear your issue is electrical. You could try removing one of the spark plugs then with insulated pliers, hold it near the block and see if it sparks.

Still feel something electrical or sensor is saying no to start up and hence why it wont fire.

You need to get the ECU read, if your car is OBD, ie 2001 or later, you can get one of the generic ones off Ebay for about £20, then post us your error codes. Clear them, then read which ones come back.

Imobiliser, check the light is going out and also, lock and unlock the car then start it, worth a go.

Electrical items that will cause a failed startup:
Immobiliser
TDC sensor
ECU fault
Knock sensor
MAF sensor (if it has one)

And a wild card one, stuck turbo

Can you tell us what were the circumstances of the failure. Have you had something replaced recently, has the car been left for a long time, did the battery go flat and you jumped it, things like that, it might help us diagnose it.

Stick with it, you'll get it sorted fella.

 

[karatemaserati]

hmmm i dont think its the spark plugs as it is firing so there must be a spark.



timeline.....

4/1/13 drove to my mums, CEL came on and limp, cured next day with throttle reset.

5/1/13 - 6/1/13 couple of short trips over the weekend all ok


6/1/13 drove my mum to hospital, nice slow easy 20m drive, everything was hunky dory,

left the car over night,

7/1/13 come down to car park, fitted a new little white and orrange NRV in the bottom right corner of the engine bay for the oil breather system. went to start... no start

cant possibly be the oil breather system, iv made sure the NRV is in right was and besides, when i had the oil breather system in bits a couple of weeks back to check the valves the car would start fine.

which one of those things that you listed above would be a bank breaker??

 

[ledlights]

Jumping back a few posts, the factory fitted relays on mine were yellow. I tapped them and cleaned the contacts but if one of these goes completely you'll just have to change it. The way to properly diagnose is to plug in an OBD2 reader, it'll set you off in the right direction.
Most of the faults Conaero's listed will show up as a fault code. When you find out what it is if its not self explanatory do a search on the forum to find out what it relates to if it's not a generic code.
It looks electrical to me, perhaps either an ignition fault or an injection fault. Both could be as simple as relays or a sensor so it might be a cheap fix.

One final thought from me. You've got fuel pressure but you might not have much flow..... If the fuel filter gets blocked up the pump can often get enough fuel through to show a decent pressure but because the flow rate is inhibited, as soon as the car fires there is insufficient to get more than a cough out of it. Then when you turn on the ignition again the pump manages to get enough through the filter to show pressure again. Another thing you could try is see if a new fuel filter helps?

Steve

 

[karatemaserati]

hmm interesting will have a look, think im just gonna get it RAC towed to Carrs in exeter iv hear they are reasonable.

 

[ledlights]

Where are you based?

 

[karatemaserati]

im in plymouth mate

 

[conaero]

Just try and undo the fuel filler cap and release the vaccume. Also switch the battery off overnight its worth a try.

Also you did for these filters, and then your problem started. Check you did not dislodge sonething.
