Re: 1990 Honda Civic HB ingnition problem !!!!!!

If it cranks,briefly starts running,then dies,and then cranks without starting,the problem may be the "main relay" which controls the electric fuel pump that keeps the injector rail pressurised. It can be removed,opened up,and the cracked solder joints on the PCB resoldered. That will save you at least $50 for a new relay.
