Co., Inc., Everett, WA Lines: 24 I would just like to second the motion on the possibility of the fuel pump cut-off relay acting up. I had a very similar problem with my '78 Honda Civic which was fixed by replacement of the cut-off relay. These relays are solid-state, i.e. transistor switching rather than mechanical contacts. There are a pair of power transistors in parallel driving the fuel pump. The failure seems to be due to one of the transistors cutting out, leaving the remaining transistor to do all the work. The symptoms are much like those described. First there is a loss of power, followed by total stalling of the vehicle. Waiting a few minutes before trying to re-start the car seems to temporarily get around the problem. I have had other problems with the electronics in the Civic. The dash board dimmer switch is also solid-state, using the same type of power transistor to control the panel lights. I've had to replace this same transistor in my dimmer in order to fix the thing. It appears to be a case of a Hi-tech, low reliability system. Still cheaper than replacing an engine control computer in a GM product (> $600). Hope this is of some help. -- Paul Lutt (206) 356-5059 John Fluke Mfg. Co. P.O. Box C9090 Everett, WA 98206 {allegra,decvax!microsof,ssc-vax,ucbvax!lbl-csam,uw-beaver}!fluke!pwl
