Im looking for a fuel injection expert?
I have built my bike up i have a good spark and feed from the coils up to the ECU but it will not energize the injectors we have been through all the wires for all the faults it says to check in the manual i can make it fire with fuel sprayed in the airbox?
I have been told it needs the fuel sender plugged in but what do i know any words from a knowledgeable expert would be greatly welcome I dont want to admit defeat and buy some carbs just yet.

is the fuel pump working? how long has it been standing?

New fuel pump full pressure powers up when ignition turned on checked the double relay its feeding power to the pump both initially and when cranking i have everything but an injection pulse i have feed to injectors,I have stripped and cleaned the injectors and tested them.
But im no electrician plus its 20 years since i was on the spanners.
so im throwing up my white flag.
Ps I found it in bits after 17 years down a cellar.
I also have two spare ECU,s

is the green light flashing on the injection ecu? when you spin the engine?

Mine has no green light it doesnt have one on the B2.
But it doesnt flash if i plug a unitrac one either.

are you getting a pulse at the injector plug sockets by connecting a bulb holder ?

No we have checked the injectors with the bulb and shorted out to test the are working ive run out of tests. lol
When i had the bulb in the plug and all the plugs plugged in nothing.
but when i spray fuel in the air box and it fires the light works but not for long.

can you hear the injector click when you do the bulb test?

only on no 1.
Just a small note i have lights on dash every where but fuel and the other 3 warning lights im going to try and fix them in the morning.

if you cannot hear them click they are duff . i would get them tested & cleaned by a proffesional

I removed all the injector weeks ago and cleaned them out and checked them one by one before i fit them they all click.

how did you clean them ? they have to connected to a cleaning fluid & fired just cleaning them with brake cleaner or thinners is no good

i connected them to my fuel pump and pressured up the rail and then energized them up one by one i also have added some strong injector cleaner to the fuel too.
Believe me ive checked everything i can think of im ready to buy carbs but im determind not to thats giving up i have fit v8 engines in cars and diesels in petrols im not going to let it beat me i was hoping someone on here might have had a silly problem ive not thought of .
Thanks for having a go.

are the block connectors in the correct places on the injection/ fuel pump relay? white block should be on the left side of the relay

Try the 750 turbo forum they are experts on the air cooled injection systems and might be able to point you in the right direction
