My truck has been having a hard cold start problem for a while, I changed the plugs to Beru's, but that didn't help though 3 of my AC delco's were bad. My truck does burn biodiesel and vegetable oil mostly. I know that probably be at least part of the problem, something in my rerouting of fuel lines is allowing an air leak most likely but I can't find it. Now's the trouble- I had to give in and have an alignment shop fix my steering that I couldn't get right and when I got it back yesterday it wouldn't restart when it was hot. I let it cool down and got it started with starting fluid. Later on, I decided to turn the IP timing back up a tad as I tried retarding it a little bit a few weeks ago, which quieted it down and lessened the black smoke considerably. Then I adjusted the external fuel screw on the back of the IP some and it wouldn't even turn over. I turned it back to where it was and it started, I don't know if it was the fuel adjustment or low batteries or what was the problem, but it ran OK until stalling while running after driving for 35 minutes. Today it had its usual hard cold start but ran fine as I drove around town for about an hour. I shut it off to unlock a gate and tried restarting 30 seconds later and it wouldn't. This is on diesel. Nothing. It has fuel at the injectors and pressure from the lift pump. No visible fuel leaks. I killed the batteries trying to start it so I can't mess with it til tommorow. One question- should fuel come from the return on the IP while cranking? I don't think there is, if there should be. Also, the near full can of starting fluid I had in the truck is waaaaay emptier than it should be, don't know how much of that stuff the alignment guys sprayed in my truck while they were working on my power steering.
I figured I'd give y'all a little background on the problem. Any advice? Is my IP toast?
