My Ranchero runs good but when you drive it and.

USUALLY A FUEL PROBLEM (THAT WILL START BACK UP IMMEDIATELY)

YOU WILL EXPERIENCE "SPIT AND SPUTTER" AS IT DIES OUT----USUALLY A CLOGGED FUEL FILTER OR A SOCK IN THE TANK STOPPED UP---SOMETIMES IF THERE IS NO WAY FOR THE TANK TO VENT, IT WILL S.UCK A VACUUM AND THE PUMP CAN'T PULL FUEL FROM IT

WE GOT THE OLE POSSIBLE SHORTING WIRE THING----I'VE EXPERIENCED THAT IN ONE OF MY JEEPS OF THE PAST----I LET IT RUN, AND SYSTEMATICALLY SHOOK WIRES IN SPECIFIC AREAS UNDER THE HOOD TO LOCATE THE SHORT WHEN I MADE IT DIE

THEN--WE GOT THE IGNITION SYSTEM........MAINLY COIL/POINTS/ TIMING/ AND MECHANICAL & VACUUM ADVANCE WORKING CORRECTLY.....................DO YOU KNOW HOW TO INSTALL/ TEST THE ABOVE STUFF?

.........NOT TRYING TO DOWN GRADE YOUR ABILITIES---ALL I KNOW IS WHAT IS IN FRONT OF ME.......I'M OVER HERE.....YOU'RE OVER THERE!

IS IT ORIGINAL?DOES IT HAVE TO BE?

I WANTED MORE RELIABILITY AND EVEN A BETTER RUNNING JEEP----ORIGINALITY WAS NOT THAT BIG OF A CONCERN WITH ME......AND IT CAN BE REVERSED IN LESS THAN 15 MINUTES
