HI guys,

 

Wonder if you could help.

 

My car will not start.

The starter turns the engine over.

There is a spark and the injectors are working as tested by spinning the CAS. We can actually see the spark when by pulling the plug out and we can see the injector spray a little inside the cylinder.

ECU diag shows code 55 (all clear)

Normal lights on the dashboard when turning the key.

When trying to start the car the engine doesnt even attempt to start, eg. the engine keeps turning like it would if there is no fuel or spark plugs.

 

Any one have any ideas what it could be?

 

Stuart

Blocked fuel filter?

Flooded?

 

I had the same problem not to long ago, it didn't seem flooded but it was, dried out the plugs, removed the fuel pump fuse, cranked it over a few times, replaced plugs and fuse and bobs your uncle

is there an imobilizer fitted?

CAS Sensor pushed all the way in? Sounds similar to mine and that was it!undernearth the 2 boost pipes on the right

Hi guys,

Daveb:

I dont think the fuel filter is blocked as there seems to be fuel getting through, when taking a spark plug out and turning the car you can see the slight puff of fuel coming out, but at a cost of only a few quid it may be worth changing.

 

 

Petes212st:

It could be flooded, but this has been happening for about a week, it should have dried out with the day or 2 I have left the car between tries. But I will give your suggestion a go.

 

Gary, there is an immobiliser fitted, at first I suspected that, but I cant see any other symptoms of it not working. I thought that immobilisers had a 3 point interception. Ignition, fuel pump and starter. The fuel pump primes, the starter turns and the dask electrics turn on. But I have a very limited knowledge of immobilisers.

 

Munny,

I have suspected the CAS too, but the fact it is sparking says to me that it is working.

 

 

One more thing I have noticed. When you turn the key to turn the car on (but not start it) you usually get an electrical sound from the back of the car which is the fuel pump and then a few clicks of relays and some priming sounds from the engine bay too. The engine bay sounds have stopped happening.

 

A strange question. If the ECU has blown, would I get a spark and fuel etc?

Also I have a chipped ECU, could the eprom chip have been erased?

 

Thanks for your suggestions.

it sounds flooded.

if you have spark and fuel pretty much should go..

also disconnect the mafs and try again to start her .

clean and dry all plugs then try again even if they look ok.

other than that you need to do a compression test. you may have a valve problem.

It'll be flooded mate,

 

And no to the chip question

Cheers I will take out the spark plugs and turn off the fuel pump and give it a whirl.

 

Compression should be OK. I did it about 3 months ago after a rebuild and the car has only been running for about 20-30 mins after that.

 

Will let you know how it goes.

you wont to give it a whirl about 5 times for 5 sec's each

Old fuel? Goes off surprisingly quickly. After 2 years the stuff in mine wouldn't even burn with a match thrown on it!

I took out the spark plugs every one was very soiled and also very wet. When taking each of them out and taking the balance bar off to get to the rear plugs the whole engine was stinking of fuel.

I have decided to keep the balance bar and plugs off overnight to let the fuel escape.

 

I have cleaned each spark plug and I will put it back together tomorrow see if that makes a difference.

 

Hi John,

 

Ironically when it had 3 year old fuel in about 3-4 months ago it was running fine. I have since put in some super, which is probably 3 months old. Its lost it's superness but should still be OK.

 

I will say how it goes after I try again tomorrow.

good luck hope it starts for you

Same here, good luck mate

I put the plugs back in today. I didn't hold much hope as this can has not been starting for several weeks, it has even been stood for 2-3 weeks without even trying to start it so how could it be wet plugs?

 

The engine still had a whiff of petrol when I opened the bonnet but I carried on regardless putting in the plugs and screwing down each coil pack before re-fitting the balance bar.

 

Put the fuel pump fuse back in and gave it a go. I was hopeing for at least some splutters and maybe even it starting after a few attempts.

 

Turned the key the engine didn't even turn over once before it started.

 

Its pouring out smoke at the moment but what do you expect when its not been started for probably close to 2 months now (Actually probably closer to 3)

 

Thanks a lot guys. My Z is a step closer to being back on the road after 3 years.

 

Stuart

good man you will be on the road before you know it

easy peasy, the smoke will soon clear mate

great always good to hear.:dance:

 

dan.:)

Bloody 'ell Stu, you not got that thing back on the road yet?

3 years and counting.

 

Is it still purple?

Have you handed it down to your kids yet LOL?

At last someone finishes a thread. All to often you read about a problem and end up having to guess whether the advice given actually worked. Glad you got here going.
