My 91 Toyota land cruiser cranks but no start?

Answer 1

HI... I HAD THE SAME PROBLEM WITH MY Toyota LANDCRUISER. AFTER THREE "ELECTROMECHANICS" AND COUPLE OR GUESS MECHANICS THAT TRY EVERYTHING, MY 2 BROTHERS AND I STARTED MESSING WITH IT. IT HELPED THAT I HAVE A TOYOTA TRUCK SO WE WOULD TROUBLESHOOT STUFF AND COMPARED IN MY TRUCK TO SEE IF IT WAS HAVING THE SAME SIMPTOMS. ANY WAY THE THING WE NOTICED ON THE DASHBOARD, THERE WAS NO CHECK ENGINE LIGHT WHEN THE SWITCH WAS ON THE ON POSITION, IF I'M NOT MISTAKING ALL VEHICLES SHOULD HAVE THE CHECK ENGINE LIGHT ON BEFORE YOU START AND SHOULD GO OFF AFTER STARTS, UNLESS OF COURSE SOME SENSOR IS SENDING SIGNAL TO THE ECM (ELECTRONIC CONTROL MODULE) SO WE STARTED DISCONECTING RELAYS ON MY TRUCK UNTIL THE CHECK ENGINE LIGHT WENT OUT, AND NEEDLESS TO SAY WHEN IT CAME TO THE EFI RELAY( ELECTRONIC FUEL INJECTION RELAY) LOCATED UNDER THE HOOD THE LIGHT WENT OUT. I BOUGHT A NEW ONE AND THEY ARE EXPENSIVE... 40.00 DOLLARS, INSTALLED IT AND NOTHING, UPSET ABOUT IT MY BROTHER PUSHED THE RELAY AGAINST THE BOX WHERE IS CONECTED AND MY OTHER BROTHER SCREAMED "THE LIGHT CAME ON" JUMPING AND CHEARRING 'CAUSE IT FELT LIKE A MIRACLE WE FOUND THAT THE WIRE CONECTION UNDER THAT SMALL BLACK BOX WHERE THAT PARTICULAR MAIN EFI RELAY CONECTS WAS LOOSE... WE TOOK IT A PART AND SECURED THE CONECTIONS AND, IT'S BEEN RUNNING EVER SENSE... I HOPE THIS HELPS YOU. I TRIED EVERYTHING BEFORE THAT TO A POINT THAT I TOUGHT IT WAS THE ECM, OR TIMING GEARS BUT TALKING TO MECHANICS THEY SAID THAT'S VERY UNHEARD OF THIS ENGINES THEY ARE HARD TO BRAKE LIKE THAT
