Question about 1994 Oldsmobile 88

2 Answers

I have a 1994 Oldsmobile Delta 88 Royale. The check engine light is on and when warm it dies while being driven. It will start back up immediately, but will die again after a short period. I have an Equus 3140 OBDI/OBDII Engine analyzer, but it won't communicate with the system. This car is one of the ones with the OBDI computer but the OBDII style connector. How can I get the codes to determine the problem?

    It does not have the 12 pin connector. It has the 16 pin connector. Looks exactly like OBDII connector.

You can either take it to Advance Auto - Auto Zone or Pep Boys as these 3 do systems checks.

Try taking down the VIN# - call a dealer and ask about recalls or Service Bulletins.
Best of it

1994 oldsmobile delta 88 royale LS was running fine than one day nothing I mean nothing , car doesnt turn over no clicking no nothing


Presuming that your battery is charged and the cables are clean and well connected (first things to check), you may have a blown fusible link. The fusible links look like regular wires except they are usually slightly larger in diameter and red, but not always, especially if they've been replaced before. The fusible links are connected to the hot post of the starter solenoid where the positive battery cable is also connected. The fusible links can be tested with a common 12 volt test light.

94 olds 88 want start


yes it can be the security system, find the two all white wires at the bottom of the steering column and cut them and solder the correct ohm resistor in between you will need an ohm meter to measure the resistance of the chip on the ignition key then install that omh resistor to the wires.
