I have a 1.7 td (x17dt lowblow) astra G van (Yep, new shape with older mk 3 engine). Anyway, about 2 weeks ago my timing belt slipped and smashed all the top end up including cams etc so i decided to have an engine from my friend, lower mileage (80k rather than 115k).
Everything is the same on the engines except for the fuel injection pumps are different. Both pumps run with the older throttle cable system but one has the sprocket where you can lock when doing the timing belt and the older one had the sprocket that you had to time with a special gauge.
I put the newer engine into the van and connected everything back up (EVERYTHING has fitted perfectly, pipes, gear box, wiring loom, even fuel pipes and i even used the old turbo as it were in better condition with the manifold).
Haynes Manual is telling me that the fuel system does not need priming, just to turn over for 10 secs and leave for 5 secs then repeat, however, this is draining my battery within minutes as the alternator isnt able to charge it as it will not kick in.
I was wondering whether anybody had any knowledge on this subject and if they knew whether the other pump needs to be primed or some procedure followed to enable the fuel system to feed the engine properly.
Any help would be great,
