DSE cutting out

Evening all, I've read through a few posts but can't find anything linking to my problem.

It's a 1998 DSE pre egr+maf, fitted an in tank pump due to faulty guage and was running fine till I went on holiday last week. When I picked up the car from the parking, started up put it into reverse and there was nothing, no movement or throttle response, same in drive but revved up in neutral. I've changed fuel filter and still the same but still same but is now cutting out in reverse then takes a fair few cranks to fire up. Pump is working, tested that while doing the filter. Very strange to me

So it revs in neutral but not in drive....??

Sounds gearbox/torque convertor related maybe!

It does eventually rev up, revs up easier in d than r, can take 5 seconds with my foot flat to the floor for it to start picking up. I was thinking torque converter tbh

Diagnostics is the only way with this one. Sounds engine ECU/fuel quantity/throttle pot related to me rather than anything to do with gearbox.

Diagnostics. There is no load on the engine in neutral. Could be a few things, we could sit here and make guesses all next week.

Diagnostics check tickover rpm should be 750 could be a sticky acuator .

Is all fine now, was bit of dodgy fuel, I threw some veg oil in, once it got through was bk to normal. Very bizarre

Not convinced you have fixed it..

Engine cutting on overrun or as gears are selected is usually down to fuel quantity servo fault. If diagnostics show a "Fuel quantity out of range" fault you are going to need a new or recon injection pump at some stage.

There are no faults stored, everything seems to be ok, the derv I used was free from a friend. Might of had petrol or water in it. It's recovered fuel from hgv accidents

Plus it's had a recon pump at some point.

Fair enough, just put it down to a dose of contaminated titty then.
