I've got a 94 p-30 van 6.5na mechanical. I don't have a service manual. Do I need to set tdc and lock the pump down before I remove it. I need to replace the front gear cover, leaks coolant. Is the pump lock a pin or a bolt? Where on the pump is it? Thx SteveinAZ

 

scribe a line in a relation to the block on your pump so you know excaltly where to put the pump when you put it back on.



CAUTION: Never engage the starter motor to rotate the engine when the injection pump is removed as severe engine damage will occur. With the injection pump removed the pump driven gear could jam in the front housing by engaging the starter motor, resulting in a sheared crankshaft or camshaft gear key and possible valve train damage. Always bar the engine over by hand to avoid internal damage.

NOTE : Removing the fuel injection pump and injection lines requires removing the intake manifold.

Removal Procedure


1.Remove the negative battery cables.
2.Remove the intake manifold. Refer to Intake Manifold Removal .
3.Remove the injection lines. Refer to Injection Lines . See: Fuel Injector Line\Service and Repair
4.Remove the fuel inlet line from the injection pump.
5.Remove all necessary harness connectors and hoses from the injection pump.
6.Remove the fuel return line at the top of the injection pump.
7.Remove the oil fill tube.
