i ran my car friday everything was fine first time at the track with the car. i drove home no problem stopped and my oil pressure was at about 20 idling but driving 40ish (normal). didnt think anything of it and at the time. a couple of hours later started car up to leave oil pressure gauge didnt even flicker. instanly turned off car. it only ran for about 5 seconds.

so i checked to see if it had a bad connection or was broke no problems started the car one more time same thing...nothing ill be putting a mechanical gauge on it tomorrow to if the censor went bad.

but does anybody know what are some strong possibilities are?
like censor, o ring, pick up tube, pump,..etc

thank you
