Hi all 

 

My wife had our car yesterday and all was normal did an 80 mile round journey then went into our local shop came back out and the car was turning over but not starting then said engine malfunction.

Called AA out and they said seems like the fuel pump.

Like I said it is turning over but just does not fire plugged obd in no codes stored.

Also it's not remote starting ie button 

Any common issues to be aware of

The issue is using generic scanners doesn't show Ford specific codes.

You don't need a License unless you want to do Configuration and Programming.

There should be a PID for Fuel Rail Pressure at the Common Rail but probably not much for the Fuel Pump  itself.

The Wireless Adaptor that you are using for Torque may not work with FORScan or may not work well with it. You can try it with the free Laptop version to see before committing to the Phone version.

If these have a tank pump, you may be able to manually run that using Forscan.  The 1.6 TDCIs didn't but I think the 1.5s do?

I've done it on my Golf to prime after a fuel filter change using VCDS.

You need to use FORScan on a laptop with a good ELM327(modified) connection cable.

Download FORScan (It's free for use on a laptop): https://forscan.org/download.html

TunnelRat Electronics ELM327(modified): https://tunnelrat-electronics.fwscart.com/USB_Modified_with_switch_ELM327/p4541936_17045457.aspx

There will be almost for sure a DTC stored relating to the problem.

Is there anything else I can try when using forscan to possibly diagnose this

Where about would that be on the settings 

Called something like 'service Procedures' on Forscan.

First check is a global scan to find all codes.  Mainly interested in PCM codes but others can also be helpful.

If no codes, second check is the service procedures, to see if there's something like 'fuel pump prime' or similar.

If fuel pump does prime, or there is no tank pump on these, third check is to use live data to see how much fuel pressure there is in the fuel rail when cranking.

 

Also, I think we covered this when you first bought the car, but there was a recall for a dodgy cam sprocket on the 1.5 TDCI.  Did you ever check whether yours was part of the recall?

Do you need the extended license for that service procedure 

I don't think so, but it's been a few years since I used Forscan myself now.

FRPS should be a good one.  If not then try FRP-A.

Could also have the desired FRP open to compare.

However, the 'error' next to PCM on your code list doesn't look good. BCM faults also point to a potential wiring fault.

Doesn't look like a simple diagnosis unfortunately.

This is what the voltage is don't change during turning over Screenshot_2022-09-05-19-29-36-65_99c04817c0de5652397fc8b56c3b3817.thumb.jpg.2c074dc2de4b00d9d7b543785f5f717f.jpg
