Bad Starting. Faulty battery and alternator already replaced, but still intermittent non start. Only code stored 01087 - basic settings not complete in ecm. Checked ignition HT all appears ok, however fuelling appears non existent on cranking(whilst non starting). Have checked fuel pump, wiring to it and relay/fuses. Checked fuel pressure into fuel rail, was all ok 3 bar. Checked injectors resistance ok, battery live to all injectors ok. Switching from ECU appears very weak - very slight sniff of petrol to air inlet fires up and injectors appear to kick in i.e with noid test light on injector plug lights up brightly as soon as it fires, prior to that very weak as non starter. Anyone got any ideas before i condemn the ECU.
