[QUOTE="Charles, post: 62274, member: 103"] You need to verify lube oil. Make up a gauge on a length of hose and connect it to the reservoir atop the front cover and check the pressure. Unplug the 42 pin connector at the driver's side valvecover with a 10mm socket and crank the engine over with with good, hot batteries on a charger and if you can't get pressure then you need to start thinking about a scored front cover, or worn gear pump, cracked pickup tube or maybe even a cracked block and things along those lines as to why you can't build lube oil. One other option is that the high pressure pump itself is bypassing all the flow directly through itself. I've had one do this in the past. Wouldn't build lube oil and obviously wouldn't fire. Swapped out the pump and lube oil shot to 40+ and it fired right up. If you've got a spare pump handy, or a loaner pump to try then you can give that a shot. [/QUOTE]
