1. Anywhere along the fuel supply line, esp. extra extra (smaller inner) flat o-ring on the fuel filter seat. 2. Bad IP mainshaft seal. 3. Fuel return lines. Could be downstream of the IP fuel OUT, or even the small fuel spill tubes from the injectors.

It's not the fuel filter, replaced that when I got the car and checked o-rings carefully. I did remove some of the fuel return lines when getting to the pump bolts, so that's probably it. We'll see how she starts today. The injection pump does have a small leak by the cold start pivot arm, hasn't been this hard to start however. Down the road I will rebuild the pump.

Too hard to be sure what's causing hard start knowing I have a questionable pump (it leaks). Still, good know my valves and pump timing are not a concern. Once I got the valve cover off I could see that both my cam seals were leaking so replacing those gives some peace of mind too. It's a shame they didn't put a petcock in the radiator, this is the second time I've gotten a sleeve full of coolant trying to drain the rad. Trying to flush out all the old junk and get some fresh zerex g-05 in as part of the water pump/thermostat service.

Might be time to hook up a low pressure fuel pump upstream of the filter, as a troubleshooting aid. Do you park the car on an incline?

The car is always parked on flat. I'm curious, what would be the purpose of the pump?
