I DID A SWAP ON A 91 FIREBIRD WITH A V6 TO A V8 HAD ALL THE PARTS FROM A DONOR CAR ,AND THAT WAS A 91 GTA SLP CAR....I CHANGED EVERYTHING ..THE HARNESS,ECM FUEL PUMP BRAKE LINES,ALL I THOUGHT I HAD TO DO YET WAS CHANGE THE FRONT SPRINGS,,SO I CHECKED ALL THE FLUIDS FRESH OIL CHANGE,FRESH PLUGS,MSD BILLET DISTRIBUTOR,SO TODAY WAS THE DAY IT WAS SUPPOSED TO TURN OVER... WELL IT DOES NOT HAVE ANY SPARK! I HAVE POWER GOING TO THE PINK WIRE THAT GOES TO THE COIL,I TRIED A NEW COIL THAT DID NOT WORK,NEW CAP ,,THAT DIDN'T WORK EITHER! NEW MODULE ,NO GO .
PULLED THE COIL WIRE OF THE DISTRIBUTOR TURN THE KEY AND NO SPARK..EVERYTHINGS SEEM TO WORK THE WAY THE DONOR CAR WORKED ACCEPT THE SPARK! AND THE DONOR CAR RAN WELL..THE ONLY THING I LEFT OUT IS THE OIL PRESSURE SENDING UNIT IT NOT HOOKED UP IT BROKE DURRING THE INSTALATION..COULD THAT SENSER BE PREVENTING THE CAR FROM HAVING NO SPARK? THE CAR HAS BEEN SITTING A COUPLE OF YEARS ALSO... THANK YOU IN ADVANCE TO THE MEMBERS THAT WILL HELP..

 

CLOSE THIS THREAD ! GOT IT ..IT WAS THE OIL PRESSURE SENDING UNIT...
CANT BELIEVE IT ,BUT IT WAS....UP AND RUNNING.. THE SWAP WAS A SUCCESS!

 

Nice! Congrats on the swap! Love it when things come together.
