I have a '98 3500 drw, 5 spd manual trans,24v diesel truck, tried to use a cen tec scanner, doesn't work, any ideas? where is the best place to buy a scanner that works. problem: engine burped a few times, tach went to zero, started working again. didn't try to run it yesterday, started right up today, ran ok, tach ok, didn't drive it. any ideas?

Thanks.
