Trying to take diseal injector pump, 3bolts holding pump in place I have 2 off but 1 on bottom inside cannot get to it with spanner. Any suggestions or help would be greatly appreciated.

Take a cheap wrench (13 mil) I think it is, put it in a vise and heat it bend it to contour the shape of the underside of the pump
Works great for that particular purpose

Yes, you’ll also need to remove the center nut from the timing gear. A pointed bar and a swift blow of the hammer is usually enough to separate the gear from the end of the pump, don’t use a flat ended bar or you’ll mushroom the end of the shaft and damage the threads, leaving the nut on a few threads while you separate them also helps protect the shaft.

Take care not to drop the nut or lose the wood-rough key into the timing cover. Good luck ?

could be fuel running back overnight, are the hoses perished? Does the lift pump work and supply a good stream of fuel?

Have you checked the stop solenoid is working properly? Unscrew it and put power to it (it will need to be earthed against something) and check the plunger is lifting properly.

There’s also a small gauze filter under the inlet pipe on the end of the pump, it’s a bit of a fiddle to get out and there’s a couple of small parts that sit inside it so take care when pulling it out.

stop solenoid-

The filter sits under big fitting, it’s like a plastic tube
