Faulty ECU causing cutting out and killing camping trip !

wondering if any of you guys can help me out with an issue that i have been having recently ? a few months ago the truck died on a camping trip to wales this lead me to be stuck on a not so smart motorway for three hours with my 6 year old this was not much fun at all ! the truck died there was no fuel pump running and i lost the temp gauge then we frantically messed with the wiring beneath the drivers seat and by amazement the fuel pump sounded and we were off again

i was convinced the problem was the small black earth under the seat so when we got to wales we removed this wire i then tried to start the truck and there was no fuel pump and no temp gauge , in my head i was excited i had found the problem so i cleaned the wire and re attached it and the truck has been working perfectly since

then this weekend we braved another trip this time weymouth ! all was good until on the way back last night and she died again with the same symptoms this time we tried the earth taken it off and back on and still it would not start with that my six year old said to me hit that silver thing dad i for a laugh and a bit stress relief i hit the ecu with a spanner and with that the gauge flew into life and the truck started he did get rewarded a MC Donalds for the idea , so im guessing now i have a duff ECU ?

does anyone on here know of any ECU repair places ? it has been chipped by the former owner so nut sure if this matters ? any help would be appreciated

thanks for the rely , i did change the injector harness when i purchased the truck last year though did not open the ECU its self maybe its worth prising it open ? just a bit worried that i cant trust it now without getting it looked at ?

Sounds like a capacitor issue have you read any fault codes? They usually show as a top side switch fault. If you loose the glow plug light and temp gauge then check the relays are making a good contact under the drivers seat.

thanks , i have checked the relays though all seam to have a good connection , when you say capacitor do you mean within the ECU its self ? it was definitely the tap on the ECU that sorted it .

It looks more like problem in wires/connectors/sockets than in ECU.
I have repaired quite a lot of TD5 ECUs, and it was never susceptible to any mechanical movement. Check wires, connectors, relays and relay sockets for any signs of corrosion or burn marks.
But before any big work, try someone with Nanocom to read faults and check live data. Without this, you are "blind". "Drobek" = The Small One - Discovery 2, "Blufínek" = The Blue Thing - Defender 130, and for me at least Ford Mondeo

Dan at Storm Tuning in Rotherham tests and repairs TD5 ecus.

Can vouch for his work, we have had a couple of customers issues sorted by him with ECUs and where he hasn’t been able/hadn’t been cost effective to repair he can usually supply a tested second hand unit from stock.
