Still no luck starting my car. I have done the following:

 

CAS

1) Checked the CAS, turned ignition on and rotated the CAS, each injector is firing. Removed CAS and put it on Cerina's, works fine. Cleaned up the connector (both sides) as it was a little green.

 

PTU

2) Removed my Series 2 PTU and fitted it to Cerina's car, works fine. Cleaned up the connectors and checked the earth wire and got 0 ohms resistance.

 

Plugs

3) Changed all spark plugs, re checked for spark but it's so small it's not worth talking about. Checked resistance of the coil packs less than 0.7ohms (well was 0 to be precise). Tried getting a spark with Cerina's coil pack, no luck. Tired testing the spark from another cylinder, no luck. Fitted new Coil pack connector on that cylinder, still no change.

 

ECU

4) Checked all the wiring to the ECU for loose connections, everything looked fine. rewired a couple that could have been suspect, but still no luck.

 

Relay

5) Checked the Ignition Coil Relay, looks fine.

 

Complete Plum

6) To top it all off I then dropped a fooking 8mm socket head down the boost pipe into the driver side intercooler :mad: What a fooking plank. How the hell am I going to get that out ?

 

Need your Help

I'm really getting fooked off with this now as it's got to be something really small and easy but I just can't find it.

Any ideas ?

this may sound a bit daft, but here goes anyway.

 

are the injectors openning and leting fuel through

 

 

there is fuel getting to the cylinders--- is there too much fuel and so quenching the spark.

 

 

 

Pete

:D

I have fuel pressure, I have turned the CAS by hand and each of the injectors are clicking and squirting.

 

I reckon that after giving it loads of wellie at Box hill, the compression in the dodgy cylinder has dropped so low that it can't start.

 

Oh well I guess I'll cal it a day there and get it towed to SE :(.

Did you check that the timing is correct?

Yep timing is fine :(.

 

Spark is fine apparently :(

 

Fuel is fine :(

 

Compression is not fine :(

Thats the problem then low compression!

I thought that you said that compression was down

on one cylinder?

- that should not stop it running, albeit not at its best.

 

If air is ok and fuel and sparks, then it should run!

 

There must be something that you've missed;

perhaps SE will find it and you'll have a 'Doh' moment.

 

Infuriating.:mad:

oh no,

I think you are thinking ok Tony C who IIRC has 80 psi in 1 chamber and 140 - 150 in the rest.

 

I have 3 chambers down (not all on the same bank either).

When we last did a cylinder leakage test (three months ago) it was showing up as follows:

Wet readings

1) 140psi

2) 110 psi

3) 100psi

4) 145psi

5) 105psi

6) 140psi

hmm, still makes no real sense.

 

If the fuel/air mix is right and the spark is at the right time

then it should fire even 'tho the chambers are down.

 

It is not as tho' you've no pressure at all.

 

You rescue that socket?

 

Any chance that the firing order is out?

Have you swapped that injector yet ? What concerned me was that we never saw a wet spark plug ....

No didn't swap the injector mate, but the plugs were wet (all of them) and I tested each injector via the cas and each was firing and spraying.

I think when we checked it it may have jsut been clogged. I put a couple of shots of injector cleaner in it a week later.

No chance the firing order is out as I've had it running a fair few times, but it just seemed to be getting harder and harder to start. Now it's not even firing.

 

Will recuse the socket tonight hopefully. Going out there now to take the front bumper off and pull out the drivers side IC.

Stu, I used to have a magnet on a flexible spring like the 'total recall' type three arm grabbers - in fact the two came as a kit for £2.99, long since broken and thrown out but I'm sure your local motor factor will have one. It was shrouded in metal and plastic so only the end was really magnetic - should be ideal for your retrieval job...

 

Sorry you're still having trouble. Presumably the jump lead from battery to plenum didn't help?? Only thought I had was if you'd had the thing sprayed recently you may not be getting good ground on a number of components...

 

Cheers!

I might be stating the bleedin' obvious here, but sometimes you gotta.

 

If I've read this aright:

 

a) it's getting harder and harder to start

b) you have a mysterious compression problem

c) you haven't re-tested compression for 3 months

 

...could it be the compression problem is now bad enough that it won't start?

PS I've learned a lot reading this thread!

PPS At least it was a chunky spanner you dropped, and not an ikkle bolt or clip... (I launched the TPS connector clip across the drive the other night but managed to find it again)

Well it was a small socket rather than the wrench itself. The reason I couldn't get it out with a magenet was because it was actually in the intercooler itself. !! :eek:

 

So I took the fornt bumper off and took the intercooler off and this is what I found.

oops :slap:

well at least you got it out .... just a simple case of putting the bumper back on then ;)

Yep done that too :D.

 

But as we all know it comes off 10 times easier than it goes on :D.

Still not lined up 100% but it will do for now
