Hi,my fuse box is in the glove box.Hope this helps!

No, I would say that if you provide power to the injector fuse and the engine starts, the problem is NOT a bad PCM. What you need to find out is WHY is there no power at the injector fuse?

The 20 Amp fuse marked "INJ" on a 1993 Oldsmobile Silouette equipped with a 3.8L engine gets its power from the ignition switch. (the vehicles equipped with a 3.1L engine do not have an "INJ" fuse)

PLEASE NOTE: It would be helpful to indicate WHICH ENGINE your vehicle is equipped with so someone trying to help you does not have to look ALL of them up.

Anyway, if that fuse does not have power with the ignition switch turned on, you most likely have a bad ignition switch. However, it could be a broken wire between the ignition switch and the fuse.

Hi, measure the voltage at grey(or white) wire at the TPS. It should be 5 volts with TPS connected or not. This is a reference voltage from ECM.
Dark blue wire should change approx. from 0.5V to 4.5V when changing throttle from fully closed to wide open. It should be measured with the TPS connected to the harness. To do so you might need to splice the blue wire or insert really thin wire in the TPS connector.

This is the oil pressure sending unit.

The easiest thing to do is get a new one, remove the old wone, and install the new one.

The oil is supposed to be kept separate from the electrical part, but sometimes they spring an internal leak. Replacing is easier than trying to get really specific about just where the oil is coming from. And once you do get specific, you almost always reach the same finding: a new unit is needed.

you need to check the turn signals relay in the fuses box under the dash on the driver side give these websites a try www.alldatadiy.com and www.autozone.com if all fails stop by your local GM dealership in the parts department and they be able to print you off the pictures and diagrams you need wish you the best of luck Michigan Man.

It sounds like the vacuum modulator is shot (this directs the air flow to the different vents) or you have a leak in one of the vacuum lines that go to the modulator. Any way you look at it, you will have to get in there to check it. I would suggest getting a Haynes manual to guide you on how to get the dash apart. It will be worth the $15.00 investment. I hope this helps and good luck.
