Hello everyone! Having installed our new 6.5 P400 into our 1998 K2500 sub urban, we are in the process of starting it. Have heard varying accounts as to how long it takes to start this engine - allowing for the fuel pump to pull sufficient fuel through to the injectors. Tried for the 1st time yest. evening, and loosened the bleed valve at the top of eng., and soon enough diesel fuel flowed through. Tried to start the vehicle a few more times, allowing for rest periods for the batteries to recharge sufficiently, and because of no start, proceeded to open up injector (8?).

Have tried on and off all day to kick the engine over, but to no avail yet. Of course, I appreciate this might take a while to do, as there may be much air still in the system; along with this being a new engine. A neighbor across the road though whose friend is a mechanic advised us just now that once fuel hits the bleed valve (as we acheived yest. as stated above), fuel should immediately go into the injector pump; then injectors, prior to fairly quick starting. This should be a quick process, in other words!!!Could anyone confirm or not if this is correct for the 6.5 engine, or might we have another, say bad issue going on here. Other than that, our eng is trying to turn over; the fuel pump can be heard turning on and trying to work. etc Just am unsure of how long this process should take overall, before it might indicate some other problem occurring!

Also, we have a brand new 5521 fuel pump, and we were wondering whether or not an air lock could capably form in it, preventing fuel from flowing into the injectors. In this possible instance, does the fuel pump have its own bleed valve? We have already cracked open fuel lines 1 & 8 from the injectors. We have then turned the engine over, but so far, no fuel comes out of the cracked fuel lines. Thankyou for your anticipated interest! Cheers Anne and Michael.

New eng and fuel pump came with new PMD (the revised 'Bullet Proof' PMD;) grey in colour. We had about 12 mths ago, purchased a new spare PMD as we had heard about problems with them, and good to have a spare. This was a black one, with remote connectors. This was bought before we decided to replace our engine with the P400. We had assumed all the PMDs produced should fundamentally all work with the 6.5. Whilst not sure whether long attempt at starting normal or not, we elected to just now replace the unused 'Black' older version PMD with the grey in colour new one. Presto, it worked!! Engine soon started up, grey smoke out the back and all!!! Yes, we are very happy harries!

Thanks BowtieButler,

For your interest. I wanted to post a video clip of our vehicle starting, but I don't think its larger size can be attached, so I will instead send a facebook link of it, that was previously posted on an Australian Holden Suburban forum here: I will keep you posted with developments:

As for the grille, Michael is making some modifications, needed for everything to fit. Some time ago, we purchased some large oil coolers (one for gearbox; the other for the eng oil cooler from Griffin, in USA. They came with fans as well and are much bigger than stock. We still have to accommodate those yet, easier when we eventually design and place our bullbar, which will assist this placement. When the engine was out, couldn't get over how much space was in the eng bay compartment; Amazing how with stock equipment only, that space quickly disappears, let alone when mods are done. Should have the vehicle back together over the next couple of days, thus will post pic of car all finished. Cheers! Anne & Michael:
