[Omega man 2]

Tried to start the car again today after puting it all together and it started for about three second and then cut again.

Took out the plugs and I have a small pool of petrol on the pistons  

What could ne causing this? :-? I'm getting desperate

[Auto Addict]

Leaking injectors?

[Omega man 2]

Had the injectors out. And all the pertol came out. So they would have been empty?

[Freypal]

Since during warmup the car will run a pre-set fuel map, i'd suggest fuel pressure regulator possibly? If every cylinder is flooded id guess it's unlikely for it to be injectors.

Maybe a silly question but are you getting a decent reliable spark? And when you say it runs for 3 seconds, how does it sound during that time?

[Omega man 2]

It ran for three seconds and wont start again

I have a spare fuel rail along with regulator so in the shed somewhere so I'll give a go tomorrow

STOP......we are all getting into obscure, rare and unusual faults before getting our base diags in place.

Ok, what has been done to the car and are any fault codes stored.....lets get the ground work done and recorded before we dive down blind alleys  

[Omega man 2]

Ok

My engine blew so I swaped it with one that turned out to have bent conrods. So fully rebuilt with new rods, rings and everything associated. Got round to the big turn of the key yesterday and this happens.

Marks  last input spot on.
You have been trying to start and it won`t you have flooded it trouble with  modern setups on engine ecu`s is the excess fuel  {choke } in old speak you just can`t push the choke off if a modern petrol engine does`nt fire up in a couple of turns it will flood adding to the problem.
You have a ignition problem.  or timing might be an idea to double check the belt timing.
And the other problem with a non start the lamda senses neat petrol [HC] and tells the ecu to cut the fuel.

paper clip test for any fault codes, post the results, if any...

Ok, lets correct a few of these misconseptions whilst we are here:

1) It is possible to stop fuel being injected on an EFi setup....if you floor the throttle during cranking the injectors will not be fired which allows the flooded pots to be vented

2) The lambdas will do bugger all as they do not operate until they are hot.....warm-up cycle effectively operates open loop to preset values.

Ok, as for the issue.

Simple things first.

1) Any fault codes?

2) Are the plug leads connected correctly.

[Omega man 2]

Ok, just papercliped it and got

0335 crank sensor (brand new)  :-? :-?
0110 Intake air temp sensor
1230 Havent got that code ?

The plug leads are in the right order :-?

Sure it`s not 0230-----fuel pump relay voltage :question

Yep defo 1230

[mantagte]

1230 is engine control relay voltage low
