Hi
i wrote a post a few weeks back about a starting issue with my 1998 P38 4.6HSE. Basically there is a temperamental issue with the check engine light not coming on and therefore no turnover. The starter is fine and has been bypassed and the fuse box changed (numerous times!) Usually every time I replace the fusebox, the check engine light comes on and everything is fine. It works as per normal for a few days and then the same old issue reappears. I therefore think it is down to an electrical fault but I am no mechanic, just a fiddler.

TBH it is not worth taking to a dealer to charge me a fortune - I have done that with a diagnostic check but as the rr was working at the time, no fault came up... £60 later!

Now this afternoon after working on Weds all day and then the fault appearing in the evening, I get in it this pm and the check engine light is back but after starting fine, a few seconds later the engine dies and the check engine light has once again vanished.

I am leaning, through reading on the forum that it may be a crankshaft sensor fault but on reality I need a pro. Does anyone know of anyone in glos who would be able to diagnose this without me having to sell the RR to pay for it!?

Sorry for the epic saga and thanks in advance for any help

This is a long shot but give it a go.
lift out the ecu and connect an earth wire from one of the corner screws on the ecu to the negative side of battery.Worked for me ;)
Temp measure of course but lets you know its a bad earth conn in the ECU
