sorry this is not youtube. not in the least.
why not google after all Google owns them. $1.5billion buy out.
and say what do you want to do with pump
play with it.
watch it shake, or buzz.

or pump simulation video, Xray like, (how it works)

check gearbox oil level as dry syncro rings can also cause your box to jump out of gear ,detent springs are only for giving u the feel of positive gear engagement.

the engine oil pumps are in the rear of the engine(trans out) and behind flexplate /flywheel, were any of these 2 engine oil pumps touched if so the flywheel /flexplate has to be timed to crankshaft position, so you might have it in the wrong position, if your talking about the diesel lift pump (injector pump) that also supplies high pressure engine oil to injectors, after replacing this there is a learn procedure for the rail pressure control valve that is on pump. this can only be done by dealer or some one with Tech2 scanner tool.

SOURCE: I have a problem starting
Seems you may have a similar problem on your machine to the one we've had....The 4JX1 has taught us a lot we didn't know before, but specificly for this particular engine. First I'll advise you check the obvious things...Make sure that your battery is charged fully. I'll explain why later. Next make sure that there's no air in the fuel system....On the filter housing you'll see a ten millimeter bolt, which should be loosened and once loose push the plunger atop the housing to remove any air....If bubbles come out you'll know that that was the problem or part of it. With this particular engine the ORPS (sensor) gives the type of problems you're talking about. The sensor in question is fitted inside the tappit cover into the oil rail (which is the cylindrical pipe fitted over the valve assembly....It has two sensors, one being the ORPS and the other being an oil temprature sensor. To get to these it'll mean removing the tappit cover which means first removing the inter cooler....then the oil feed pipe which fits into the side of the cover, Remove all the screws (five each side and three at each end)....The ORPS is the smaller of the sensors....It is a sensor which operates with a cystal....The oil preesure pressing against it will cause a very small voltage which is actually a pulsed signal....That signal is sent to the management computer and controls the solid state switch which allows the circuit for the injectors to beecome active....Remeber the battery? If the battery is not able to turn the engine at what you'll hear as a normal speed the oil pressure will not be enough to send the signal which opens the injectors....The ORPS (Oil Rail Pressure Sensor) cost's about two hundred and twenty US$ and if you do the job yourself your probably save a similar amount on labour charges....The engine oil is also critical....Only use the recommended oil....If that has not been used....Buy double the amount of the correct oil and two of each filter....Drain what's there and then refill with the recommended oil (once vehicle is up and running) run the engine for thirty minutes or so (pref on the road) and then re drain and again fit the other set of filters and refil....We don't like the chemical engine flush addatives, too dangerous, esspecially in a diesel engine.... Hope this is help Ron Let me know how you get on. you can send your reply to this same web site...I'm one of the experts.... Cheers for now.... Best regards Johngee10
