i am still haveing problems with my j plate 940gl.the problem was with about 1/4 tank of petrol the car would suddenly stop then start after a few minuits of cranking, and give the codes 121 maf signal faulty or absent,and 144 load signal from fuel injection absent or faulty.i changed the in tank pump (new unit)and it ran ok for a week even down to nearly empty,put £10 fuel in tank and within 5 minuites it cut out twice and gave the same codes.this morning it cut out again but this time gave the code
232 fuel supply too weak or to rich at idling and 144 load signal from injector absent or faulty.would the problem be with the main fuelpump,fuel filter,or fuel pump relay if so how would i check these.im now getting p$"£^d off with it .i am also doing this with low funds.
