92 olds 88 royale somedays it will cut off on you while im driving but it always starts back up you thought it was the fuel pump but its been doing this for over a month now?

Answer 1

Are you getting the security light in a lit position when this occurs? if so you may have a problem with the security system/passkey chip (small black chip in key) not sending its ohm value reading to your security system (shutting down fuel pump/and motor) and if after about three minutes it restarts correctly sometimes and or the security light comes on/off for no reason this may be your problem. Passkey system can be bypassed by reading ohm value of resistor in key (black chip) just read ohm value and got to a electronics store radio shack's electronics ,etc and make up a resistor of similar value as reading given from meter when ohm-ed out ,trace out wires from lock cylinder and solder in you new made up fake out passkey and bingo security system is now bypassed with out allot of hassle. Just MAKE CERTAIN YOU ARE CUTTING CORRECT WIRES FOR PASSKEY LEADS TO IGN CYLINDER! IF UNCERTAIN YOU CAN TRIGGER AIRBAG BY MISTAKE!!!!!!!!!!!!!!!!!!!!! VERIFY CORRECT WIRING. GOOD LUCK IT FIXED MINE AND WAS WELL WORTH IT !!!

P.S. If radio shack can`t get you what you need try mouser electronics or digi key!

good luck!
