After WEEKS of work and many hundreds of dollars. My Delorean has started and driven under it's own power for the first time in 16 years!
Some of you may have seen that I had a strange hard start issue. After scooping out pounds of varnish from the tank and replacing all the fuel pump components. i was unable to get the car to start and run. It would start only if i removed the fuel pump fuse and ran it off of accumulator pressure only. Running it that way confirmed that the car did in fact run. but was not able to get consistent fuel delivery.
I replaced the cold start valve, but the old one appeared to be OK anyway, so no, that wasn't it. I cleaned a checked all the injectors and they checked out ok. The symptoms did not match that of a bad warm up regulator, so I ruled that out for now. Frequency valve seemd to work. So what was it?
After many calls to both Stephen at DMCH and Danny at DMCCA, Danny finally suggested i check the plunger in the fuel distributor. It could be stuck wide open and causing a hyper rich situation that was flooding my cylinders. I removed the fuel distributor and sure enough, it was stuck fast. 45 minutes with a touch of acetone sitting on it and it was free. I reassembled everything and she runs beautifully!
Everything seems to work ok except the blower motor for the hvac system. The angle drive even works! (for now)
