Hi all. My 1992 cav Sri has a problem, when ignition is turned on, pump relay clicks constantly, injectors are firing and pump is running. When it starts and clears all the fuel from the bores it runs ok,  e m l is on . 
Any help would be appreciated

e c u. The car was  stood up for 5 years before I bough it.
