I have a '74 with a 2.2 L with dual carbs. I just swapped the engine and used all of the same accessories as the last (running) engine. Now that everything is bolted up, I am trying to crank the engine and nothing is happening. Here's what I have:
Both large wires connected to connector 30 Single wire connected to connector 50 Fully charged battery Voltage reading from connector 30 to the vehicle floorboard When I turn the key, I hear the electric fuel pump kick on then get one click and that is all. I tried connecting a remote starter switch between 30 and the other large connector and got nothing. I also connected the remote starter switch between 30 and 50 and got nothing. Any suggestions on where to look next? Is the starter bad? It worked fine before. Thanks, Ken |

Begin here. . assuming you have the starter connected correctly,
do you have 12v on the large yellow wire at the starter with the key in the start position. . If yes. . then bad starter or solenoid or ground. . If no, test yellow back to the ign switch looking for an open. . . Hint You've got a 74 right. . still have the seat belt logic switch under the drivers seat ?? another test: If you short the yellow lead on the solenoid to the battery cable terminal lead, the starter should crank. . make sure car is out of gear first ps testing with a meter is not the same as knowing the trans strap is a good ground. . since you're measuring battery12v to a known frame ground [ the floor], you did not test the ground strap as a path in this case. . . . see if you have 12v using the trans as a ground source?? the starter needs an absolutely solid ground connection to operate. . |
