Greetings,

I would be grateful for guidance on this problem.

Background: This vehicle was driving normally when a "warning light" appeared on the dashboard. Customer drove it home and next day it failed to start. It was taken to the local Peugeot dealer and they could find nothing wrong with it (after spending £400 of customers money ). Customer took it home after running out of funds for further diagnostics and sold it as seen to a local garage.

I was asked to make an initial appraisal and came up with the two fault codes. The DPF was removed and investigations found that a sniff of the good stuff would make it run. Cracking open an injector showed no fuel present. The garage thought it might be an ECU problem and it was sent off to BBA for testing and they thought it might be a problem so they provided another ECU. Still no start.

Today I had a longer look at the vehicle and found on cranking the following: Engine speed at 285RPM, Fuel Pressure at 300 bar. The two fault codes were still present. I found cranking voltage of about 9v on either side of the injector. Now, electrics is my weak point but I thought one wire should be earthed. AD tells me that the 2 wires on the injector go directly to the ECM.

So that is as far as I have got today and I would be grateful for suggestions on what further tests should be undertaken.

Regards

Pete M
