Tripac cold start problem

My tripac runs rough and sometimes dies on first start up. If it dies it usually sets the eng code. After the first start up it works just fine for the rest of the break. Any ideas on what the problem could likely be?

 

Bought the tripac used with 2800 hours. All the filters have been changed within the last 300 hours. Its on a 670 Volvo and they relocated the inline fuel filter for easier access. My first thought was glow plugs. Any idea where the fuel pump is, and how much pressure it should put out?

 

I did some troubleshooting. The inline filter was clogged. Changed it out. It helped a lot. It usually still dies after first start up. But it does run a lot smoother. I suppose I will check all the lines for kinks and replace the seperator again.

When I get home I'm gonna try to find a bigger in-line filter at the parts store to adapt to it. Hopefully a bigger filter wont clog as fast and be cheaper to boot.

 

Update: I did some troubleshooting. I took the fuel pump outlet line off at the inlet to the fuel/water separator filter base. It was barely pumping any fuel. I had already priced a fuel pump through the company I'm leased to. Even getting it at cost it was over $150.00. The exact same cheap junk pump (minus the wiring connector) is all over ebay for 25 to 30 bucks. Theres no way I was gonna put another one of those pieces of junk on there. So I did some research and found a high quality pump at Napa made by Carter/Federal Mogul for about 70 bucks. The part #for the pump is P4070. It comes with a bracket and mounting hardware. I had to drill a couple extra holes in the bracket to gain clearance for the flywheel. Also had to intall 1/4 to 1/8 inch pipe bushings in the pump to match the existing fittings. I cut the wiring harness off the old pump and soldered it to the wires on the new pump. It was a little extra work but it will be worth it to have a high quality and reliable pump.
