I'm wondering if the injection pump has sticking internal parts from setting, that can cause no smoke at exhaust when trying to start. Lots of pumps I repair/calibrate lately come in with stuck metering valve and/or rotor plungers from setting.

Turning key left to first position turns Thermostart to HEAT position, and needs held there 14-15 seconds, then turn key further left to HEAT-START to draw warm air in and start engine. Also, what brand fuel filter did you use? If NAPA/WIX brand MAKE SURE there's NO extra O ring in filter TOP OUTER groove, that's the fuel inlet passage and MUST NOT be blocked.

The main focus of this page is to show how I upgr
