No RPM? Relay drivers not working? Perhaps you have a dead P259

[laine_16v]

Yup same injectors.

What did the plugs look like after that event?
What's the cranking timing looking like in comparison to the cranking advance on the software?  Have you got a simple timing light or one with an adjustable advance (as these don't work well with wasted spark and will show double the advance unless they can be set in 2-stroke mode).

How do you know that channel 1 is constantly on?  You're going to get flooding problems if this is the case.

Have you tried swapping the wasted spark pair around?

Um i snapped my spark plug tool and havent got a deep anough socket to take them out unfortuantely lol!

Havent got a clue about crank timing, and crank advance, but abosolutely none of the configuration has changed anyway, dont have a timing light.

I've just purchased this: http://shop.vems.hu/catalog/product_info.php?cPath=1_5&products_id=44&osCsid=0018c27c029a3032a91c615f4780188f

To redo my wiring completely, should fix it then

[rob@vems.co.uk]

Is this on the same engine as the VEMS was setup with? 

[laine_16v]

Not quite, the engine was rebuilt, high compression pistons, and a different set of cams....but anyway update...

After much much playing i got it started!

I changed the crnak sensor wiring for some dedicated new stuff, to see if it made a difference, it didnt. BUT it consistantly reads crank speed about 75% of the time now.

I got it to run by unplugging injector 1, it would splutter lots and then just about get enough momentum to start, when it started the crank reading was fine, would rev upto 4000rpm fine, didnt want to rev it higher on 3 cylinders.

SO i decided to plug injector 1 back in, and the engine died straight away. ?

Can someone check my megasquirt file settings to check they are ok?

Once the engine had started on 3 cylinders i ran it for about 2 minutes before it cut out (when i plugged injector in), then after that i couldnt get it to run at all, so im guessing the spark plugs are aboslutely drenched ?

I want to work out this injector problem now. Ill put a link to my megasquirt file in a bit.

Also is there a way to boost Crank sensor signal a bit? i reckon that is all it needs...

Link to my file..

Nothing looks too nasty in there, just as an aside though:
Extras -> Boost alternate settings should be all disabled.

Here's what I'd do...
Move the wire for injector channel 1 (EC36pin7) to channel 16 (EC36pin9)
In MegaTune Settings->Injector Outputs change Injector output 3 from 1 to 16

[laine_16v]

OK ran a few little tests....

Injector Plugs

12v feed

Plug 1 = 12.15v
Plug 2 = 12.15v
Plug 3 = 12.15v
Plug 4 = 12.15v

Injector grounding, with ECU connected to loom, but ignition OFF completely.

Plug 1 = Grounds to earth ( Ohms 5 <)
Plug 2 = No Ground
Plug 3 = No Ground
Plug 4 = No Ground

Injector grounding with ECU dissconected from loom

Plug 1 = No Ground
Plug 2 = No Ground
Plug 3 = No Ground
Plug 4 = No Ground


Am going to try swapping injector 1 to injector channel 16 now...

[laine_16v]

Have swapped to channel 16 and that has stopped it from firing constantly. Still cant get it to run, i think the car is out of fuel now.

check that you've not contaminated your oil with petrol, big end bearings don't like it.

Rather than desoldering each pin you can use a piece of tinfoil to surround the chip then go at it with a heat gun(on low) With some pliers you can lift the entire chip right out.
