I appologize for not posting an update but there really wasn't any. Still no start. Getting closer with suggestions provided. Fuel lines 1 and 5 seems to be getting fuel okay, 2 and 4 iffy but 3 nothing and have tried starting when the temp was around 50. Still, I would think it getting enough fuel to get it going. compression is all around 290.

I like the look with the by-pass primer and the new primer on the lift pump is a bit of a pain to prime, it looks cleaner and I believe it's a better setup

For some background: I was rebuilding my original motor because it was left sitting for a long time and somewhere in that time someone killed the motor with what I believe was ether starter fluid. Crack rings and 1 piston had contacted metal possibly something from a pre-chamber or broken glow plug element. I did get it to start but smoke alot and had power issues. I had the head and block redone and the block received new sleeves. My problem was that I had the sleeves bored to 91, thinking that was stock but by piston are a tad smaller, so getting a new set of 5 pistons that are 90.97 @ $600.00 plus but my project on hold

I found a "good" motor for a 76 300D that the body was shot but the guy said the motor was too good to get scraped. I bought it and it sat around for a year. Too many projects, house repairs and painting, sailing and keeping my 85 300D running

Now I am really not sure what to do. The motor showed some strange waring on one of the lobes when I was adjusting the value and one of the oil cooler lines was repaired with clamps, so not sure if it ran dry or not. Because my car originally sat for 10 years, the fuel tank has issues but before getting it resealed I was testing my "new" motor by bypassing the fuel tank. Once the motor was back in, with not too much, I was able to get it started and to be honest, it sound real good for the 5 min or so that it ran, then my gallon fuel tank moved, the motor sucked in air and it's been dead ever since

I took apart the pump element for # 3 and putting back together with no spring, fuel shoots out, once the spring is in, nothing. one problem is the Delivery value has the copper washer on the top and according to my diagram, it should be seating on the washer, put it ran before and concern about doing more harm trying to change this. Since the transmission was out and dry, I don't think push-start is an option

My next step is to swap the IP put with the little room in these car, it looks like a real pain and it may still be a good IP with air in it. Another thing, I think it ran some biodiesel.

When I try starting it, still sound like there is a little combustion and yesterday I sprayed WD40, it sounded like it fired once on all cylinders then nothing again

Sorry for the book and any suggestions are always appreciated
