I thought I was finally going to get to drive it this evening. I had about 2 hours at lunch today to go through the things I found that were wrong. First I removed the intake and repaired a small leak at the IP. Next I re-wired the alternator so the engine would shut off with the key, then I pulled the bottom off of the fuel filter to repair a seal and finally I pulled the mechanical pump to see if it was installed properly. I got the pump off and found my problem, the pump arm was not against the pushrod that actually pumps it, therefore it was not pumping. This explained the problem I was having of it running for 10 minutes then dying. I was priming the car using the electric pump for about 5 seconds before I started it, I turned the pump off after about 5 seconds because it is the pump I installed for running WVO and it has way too much pressure for diesel (that is why I had to fix the seal on the filter) so the car was running off of the pressure built up by the electric pump, once the pressure is gone the engine dies. Unfortunately by the time I got around to re-install the pump I was running out of time (plus I was laying under the car with diesel dripping on me) and must have rushed the installation because when I started it this evening it did the same thing (ran great for 10 minutes then died) The plan for tomorrow is to install a lower volume electric pump so I can run it all the time with the mechanical and I plan to pull the mechanical pump again and take my time re-installing it to make sure I get it lined up properly with the pushrod. Hopefully everything will work and I will be able to post some driving impressions!
