i had a spare relay i tried that, still nothing :( i followed the wiring there doesnt seem to be anything wrong :( and when the fuel pump primes the relay makes a noise (its always done it). also checked the ecu doesnt seem like there is any leeks .... this is a bummer :(

I wonder if the 'Start yeah Bastard solution" was a false result, it would have started without the can anyway.. That's the one test that pointed to the fuel side being the problem.

 

How do you get it to start when it has refused to?? Will it crank a dozen times with no hope, then suddenly start on the 13th, or is it after you fiddle with something? Having it reliably not-start is just as important for working out why it won't.

it can't be spark coz i checked the coilpacks they tick, new sparks. also iv used start your bastard more than once to be sure it is fuel and everytime i spray into the itb's it starts then dies once the ero spray is finished. and last time i cleaned the fuel rail and fiddled with the ecu wiring and relay and it started, and i drove it for a week..... its deffs a fuel issue :/ new pumps they prime etc but yeh I'm lost :(

Have you tried taking the fuel line of before and after the rail to see if fuel pisses out when you crank it?

yeh it does the in line bbut the out only dripps :/

the injectors were cleaned and tested nothing wrong there unless its a wiring issue :/ but I'm no sparky so i can't really tell :( haha

replaced the 12v relay still nothing :(

Once it starts it does run fine??

 

I assume there is a cold-start part of the ECU program, separate from the warm-running program. Is there hardware associated with that?? Some enrichment device or air bleed that might not be working correctly.

This car is such a custom made thing that we can only take stabs in the dark.

 

I would get inside that ecu, and see what is happening when it wont start.

 

If the wiring is anything like i sold it, pretty much all of it needed to be replaced!

it doesnt start at all :(

Dave its a new wiring loom coz its a different motor i don't think it has anything to do with the chassis wiring, more the engine harness. but I'm totes puzzled :(

update, took the sparks out they are dry as fk :( so defs not getting fuel, the rail gets fuel but its not getting through. borrowing a mates multimeter to check the injector plugs this evening !

I'd try and find a fuel rail you can borrow or buy cheaply and swap it over.

That really doesn't sound right, It could have a major clog or corrosion.

i don't think it is the rail coz i pulled out the hose on the other end and fuel pisses out :(

Get an LED bulb if you can, use it to test if your injectors are pulsing. Normal bulbs wont flash fast enough.
