FORD GUY NEEDS HELP FROM CHEVY/GMC
Permalink  
 


guys i am working on a 1972 gmc 5500 flat bed truck...  the badges on the side of the truck says it has a v6 but under the hood is a BBC. i took off the valve cover to get casting numbers and casting numbers in the head valleys come back to a 454....truck has been off the road and not started since 1994. has been stored indoors the whole time.

so he wanted me to get the truck back on the road so i am in the process of doing so.

first thing i did was change oil and filter

replaced battery with a new one

took out gas tank and cleaned it.

checked radiator for fluid it was empty but for the time being i filled it with water just for now.

put 15 gallons of FRESH gas in the now clean tank

turned over the motor to make sure that it was not frozen. turn over by hand with no problems.

so now i tried to fire the bad boy up. at first it took a while for fuel to get to the holly carb but then it finally did. then fuel started shooting out of the carb. so i ran down to NAPA and bought a complete rebuild kit for the holley. great kit but a PITA with all the little parts but it is done and came out great. so i finished the rebuild today so i put the carb back on and tried to fire it up.

cranks cranks and cranks did not fire up... so i was like damn must have no spark... so i go and check. well what do you know   NO GOD DAM SPARK...

i took a multi meter and check the 2 wires that go into the coil and no power..

 

so my question is what guy you guys recommend me doing to find out why this thing is not getting spark... the points where i tried to get a voltage reading was pretty corrosive also so who knows if i actually got a correct reading.

so thats where i left off today please help a FORD guy out

 

thank you

 

mike

P5170015.JPGI'll take a shot. Run a wire to the " + " side of the coil ( not the distributor side)from the + battery terminal.This bypasses the ign. system and that should get power to the points.Clean the point contacts if they're crappy and gap to .018 (matchbook thickness) at the top of the open cycle. If the coil is ok it should at least fart even if the capacitor is junk. Hope it helps.smile

how can i tell if it has points or cap and rotor

on the back of the motor looks like a cap that the plug wires plug into. it looks like a cap that im use to seeing on a 350 that i have worked on before

Connect it .It takes the place of turning on the ignition and bypasses the key and wiring to power the coil.Key only needed to turn on starter. If it starts you pull the wire off to turn it off.Then we go from there.
