I just finished replacing the tandem pump, starter motor and thermostat and tried to start the van but it won't start. The engine turns over better than ever before with the new starter motor but it doesn't catch. It's not even close... The last thing I did was priming the fuel line by removing the return connection and turn the ignition until fuel arrived. While working on the van I disconnected the injector loom and the connector close to it, on the front side of the engine. I'm a little worried I pulled too hard on the cables when I pulled it off its steel mount. Does anyone know what that connector is for? How do I troubleshoot this? I'm not sure where to start..
