The CEL on my 95 del sol comes on everytime when i start driving my car after the engine has completely cooled down, when i leave for work, lunch break and in the mornings when i leave work, its all pretty random i check the code on it and was throwing a 43 Fuel Supply, it just started doing this saturday, ive read a few things online search's most have said o2 sensor then a few have said fuel filter, pump, but my car runs fine, no bogging down or anything. Any ideas?

Thanks

 

Well figured out the problem was just a power wire that the owner that i bought the car from had running to the trunk and it must have moved and was grounding out on the the chassis. moved that so it wasnt arching anymore, reset the ecu and drove it for about 60 miles lastnight and no CEL so hopefully that was it.
