Please include the ribbon- IBM type cable from older VE type pump only, main lead from pump control module to host loom. With the pump when sending for testing. As about 35% of these leads prove to fail when tested, but the host pumps are ok. But these can only be tested with pump or by substitution with another cable. CAN bus twisted pair type wires are very reliable and have proven not to malfunction.
ENCLOSED with the pump should be:
Details of vehicle make, year & model
A list of vehicle fault symptoms and any diagnostic work carried out.
Return address, phone number and current email address (as we are moving towards paperless system of reporting & billing).

Pumps travel well inside a cardboard box, padded with newspaper (please drain off fuel & plug orifices if possible, wrap pump in sealed black bin-bag before packing, as not to offend my postman with the smell of diesel). The cheapest option is ParcelForce48 available at any Post Office, which can be tracked via Royal Mail website.

Note: EDC diesel injection pumps cost a fortune to replace new! £900-£1500. Exchange ones are about £515. Testing at £69.50 is good value against replacement, if only to prove its working & exclude it from the diagnostic process, proving function of the pump by the substitution of an expensive new one, is just a waste of money. Bench testing is the only definitive method, because it excludes the vehicle's host wiring & fuel supply.
It is inevitable some pumps sent for testing and inspection are unrepairable! Some pumps are so borderline for repair, if we were to repair them they may not last the length of the warranty. We on occasions take the commercial decision not to repair. In the long term this is better for the customer. It negates the painful task of having to remove the injection pump for a second time to return it for a warranty claim.
Info about re-programming: PSG5 pumps. If you are considering fitting a second-hand one! Most VW & Rover pumps will need re-programming, its a bit hit & miss with GM Vauxhall & Ford, some will need programming, some will not! Its a bit of a myth that they all need doing (ex main-dealers). It's all to due with matching protocol & setting the parameters, not security numbers. But it has to be said, that several of our trade customers have retro-fitted second hand pumps, expecting problems and they have subsequently started & run ok. Very few EDC pumps will need a Bosch KTS type laptop connected to the 16pin diagnostic plug on re-fitting, to set min/max fuel delivery, IE volume, idle speed! Governed RPM min-max. All the settings are the same ex the factory, these settings only get altered, if the pump has been fitted to different vehicle, or the settings have been changed in an attempt to overcome a problem. Bosch pumps are the most user friendly in this department.
GM Vauxhall EDC pumps are notoriously difficult to diagnose in situ, many main dealers fail to conclusively make a diagnosis, we have heard from our trade customers about horror stories about new pumps being fitted when not needed.
Early EDC pumps are known to fail from "cavitation" due to an ingress of excess water. Water separates out from the fuel over time in diesel filters, and if the filter housing is not drained down at the correct service intervals. The water will damage the pump beyond repair. Most car manufacturers are now fitting new type water level sensors to filter housings on new models. Supermarket fuel is jokingly called emulsion in the trade, due to its high water content. Its cheap for a reason! Some early VP44 pumps are known to fail due machining errors in the axle rota head, a few of these wreck the alloy pump body, rendering the pump unserviceable.
PSG16 (Twin plug pumps) This Bosch 44 terminal version contains a read/write 16bit flash memory in the PSG16 module. Where the engine management maps are stored. Other issues are that the headers are pump assigned which you cannot change or interchange between used pumps, spooling solenoids are the same as the PSG5 units and can be interchanged.

We will ring on the day of the test. Please do not request a test report long after the test has been enacted. The imformation will simply not be availiable. This is aimed at keeping our test fees as low as possible. It is also how the trade likes it. No delays in quoting out repairs and returning the pump in question. We reserve the right to charge for a written test report after we have provided the information verbally.

Warranty exclusions – The warranty of our pumps and injectors will be void if any of the following are found upon examination: Fuel damage. Water contamination. Acid/chemical contamination. Dirt or other foreign material. Unauthorized adjustments. Physical damage. Incorrect fitting or poor electronic commissioning.
Fuel damage. Water, corrosion, contamination, and rust are some of the things we have seen inside failed VP44 injection pumps - Bosch refers to these conditions as “Contaminated Fuel” and invalidate warranty as a result. Savings achieved by using alternative fuel is likely to cost you a lot more long term, especially when your warranty claim is rejected. Modern injection pumps with high pressure and the close tolerances cannot survive the abuse caused by cheap alternatives. It is crucial that vehicle owners are aware of the potential hazards of alternative fuel. We strongly advise that when a pump is repaired or replaced, the customer also inspects the fuel, fuel tank and fuel filters, because bad fuel left in the vehicle can cause quick death of the repaired or new pump. Only the customer has control over the fuel used and must take responsibility for that factor.
