if WVO is the problem, why is it cranking smoothly after it cools down? IP tolerances tighten up as it gets cold? HMM.
slow cranking is usually one thing, lack of volts to the starter. either inspect the cables and VERYFY they are clean and tight on both ends of both cables. or have the battery totally tested out with a REALLY good test kit. one that will put on actually 500amps or so and verify the battery's full voltage output for sustained cranking.
that said, unless the motor is REALLY cranking slow, if there is sufficient compression, it should fire.
when was the last time your valves were adjusted?
have you ever tested your compression?
if it's low, you might want to soak the pistons in some MMO or DIESEL PURGE overnight with the glow plugs out and spin the motor over in the morning before putting the plugs back in.
see if it helps the starting situation.

If you do this, you'll be amazed at how nasty the liquid will be that comes out. Please post some photos if you do this!! Motors that have been run long-term on WVO are so horribly disgusting on the inside, combustion chambers all caked up with layers of burnt crap, valves and piston rings clogged with crap, it's *really* nasty.

I would try running it on some diesel or better yet may be some keroseen and may be get the injector pump checked prefessionaly or you could remove the metal fuel lines and crank the engine and see if fuel is welling in, could the injectors be blocked? is the intake manifold blocked make make sure the engine is getting air, remove the air filter tubing that fits onto the intake manifold (big rubber tube that conects the filter with it) then try having the tank filled with keroseen only, bleed the system and try push starting it down a verry hill serface but be safe and all glow plugs extreemly loose? might want to check that

but I'm no professional what do you guys think
PS: I did'nt check the spelling sorry

The injection pump could be weak and this would be the reason behind the starting problems. I think heat-soak is at play here, your IP is not creating enough pressure at cranking speeds, thats why when the motor is cold the motor starts up.

Thanks Guy's for your help.
Tankowner, you are right about me not telling about WVO and the crap in the tank. I think that it is the culprit here.
I am going to change my signature, I forgot how to do it can someone please remind me.

Well, I went to the car this morning and I took off the fuel cap and stuffed a shirt in the filler; it started right up, then I drove it around 5-10 minutes and got it hot, cut it off and it fired right up again, on, off, on, off several more times and it started fine each time.

I cracked open each injector and all 5 were spitting fuel out.

I decided to continue to drive me girlfriends car due to the fact that if her car is in the Panera Bread parking lot and I am broken down around town then it will put us both out.

We will see what happens tonight when I go back to the car and go home.
