Question about 1989 Chevrolet K3500
Hi Genovative, The vehicle sounds quite old so have a look at the pick up sensor in the distributor. I think Pat's advise is very good regarding the earthing problem so that would be a good area to recheck. (Even new fuel pumps can be defective!) I think the reference pressures Pat has given are a little on the low side (but I may be wrong?) I think the pressure should be closer to 4 bar which works out to about 58 lbs per sq inch. Regards John
