mine was flooding the other day and thought it was ecu not to sure if it was but swapped it and cleaned all the earths in the engine bay. also on the number 67 relay there was a bridge wire that previous owner had put on there that kept pump running constantly so took that out and slapped the relay a few times and seems to have sorted it out. so now im thining my flooding problem was down to that wire and relay so id look at that first. what is your fuel pump doing b4 you start it ? does itprime then go off or stay on ?

just con check the fuel rail in situ. haynes will give you readings to expect.

this will tell you if the injectors are biffed.

think il ave to get the fuel rail & injectors out on weekend to check seals,it stinks of petrol only on starting. smells strong on top of injectors engine floods and chokes up then few revs and then clears.
ive cleaned all  eath straps,wot about the coil......

that won't tell you much TBH   it will tell you if there are any electrical faults but the only electrical thing in an injector is a coil of wire.  if the injector has stuck it will still have the same reading just spray fuel all the time and this is a much more common type of injector fail.
