I have a 2000 speedster 240 efi that wont start.I getting spark but no fuel so I put in a new high pressure fuel pump and have 36lbs at the pressure regulator.So I took out the injectors and they are clean an spray fine.I dont think iam getting a pulse to the injectors.If I pour gas into the plug holes it runs until the fuel burns out.What am ai missing that pulses the injectors like tps,oil pressure switch,or something like that? Thank for any help flowerpot
