Yo Guys running out of ideas on this.

Car was dead have had no time to go down and run engine for couple of months, battery good but flat charged back upto full power.

Tried to start nothing not even a hint of starting
Hotwired Fuel pump to check it works and get fuel pressure up it may have had and empty tank filled up with 20 litres of gas too
turned over again coughs once then nothing hmmm strange got pressure and plenty of gas.
So pulled plugs out were a little bit black as was running a tad rich but nothing major cleaned them anyway but more importantly they weren't wet at all totally dry.
tried again still won't start still turns over good etc.
scratching head for a while only thing i can think off is if the injectors have clogged up from petrol sitting dry for couple of months or maybe ECU is shot or in safe mode from being dead for a few months.
Going to try and kick start with Easy start ethanol spray had same problem with carbed one fuel pump wouldn't kick in unless engine was running for a little while thinking maybe the ECU won't dump the fuel in unless it knows it's okay to run with the engine already running? anyone else experienced this with the FI system? although it's b20a it uses the same shitty FI and intake manifold so pretty sure it's all the same.

thanks Rich.

If you can't get to fire over with starting fluid. If you have a pinout of the ECU wiring harness connector, back probe each pin that goes to each of your injectors for voltage with a DVM. That will rule out your ECU not sending a signal to the injectors. Check the main ECU relay also, if their is one in the circuit. (you'll need someone to turn over the ignition while testing the wires though)

Need a high dollar scan tool or oscilloscope to look at the pulse width.
