There are pictures though so you know what you are looking for. https://www.google.com/search?q=1987+Oldsmobile+Toronado.+turn+signal+flasher+location ..

Do you mean wiring diagram? Or firing order?

I had a car I needed to drain the gas and I cut the gas line then purchased a connector for the cut line when I put it back together. Be very careful you don't have a fire.

Under the passenger side dash behind the glove box Hope this helps Mike

The gear selector switch is either out of adjustment or it is bad. Loosen the two bolts holding the gear selector in place and turn it slightly to see if the display stops flashing. You will have to manually shift the transmission lever at the switch into neutral, and then turn the switch until the display says neutral. Tighten the bolts and then check all gears. It's also possible the shift cable could also be out of adjustment. Does the display change if you simply wiggle the gear selector lever?

Sounds like you have many more than just one problem. It really doesn't pay to throw a bunch of parts at a problem and hope it's fixed. The climate control head display shutting of and coming back on at 75 degrees is most likely due to a bad Central Power Module, a common problem in older Toronados. Hard to find, not too hard to replace. It's under the dash to the left of the steering column. The no spark problem could be any of several things. Did you check for good cam and crank sensor signals? Do you have spark at the plugs? Have you changed your plugs wires? Do you have any stored codes? If the console says there is an electrical problem, you can be assured that there is indeed an electrical problem somewhere. It may not have been severe enough to cause a concern for the past seven years, but it may be worth taking a look now to see if has anything to do with what going on. Replacing the oil pressure sensor is easy enough and inexpensive enough as a first attempt to fix the gauge readings acting funny.

ECM requires both crank sensor signal and cam sensor signal to fire the coils. Check for spark at the plugs first. Check the plug wires, then the coils. Only if you have no spark at any coil would I suspect the ignition module, and even then only if you have a good crank and cam signal. Do you have any codes stored in the ECM? They could help pinpoint the problem.

is yours carb,if not 23- manifold air temperature (mat) sensor or circuit (1990 and earlier models) 23- intake air temperature (iat) sensor circuit (fuel-injected models) if its carb,,,,,23- mixture control (m/c) solenoid or circuit (carbureted models)

Along the left side frame rail, under the car. When you are driving the car you are basically sitting right above it.

What codes? Why did you replace the crank sensor? Do you have spark at the plugs? Do you have fuel pressure? Is there a message in the dash display?

There are about 15 of them Have to start doing some testing to find problems

Try pulling engine codes , possible crank sensor.

Since it is an older vehicle, check under the dash for any "rigging" that might have been done over the years. Start at the battery and follow all electrical wires that lead into the dashboard and fuse panels and check for any frayed or split lines that might be causing you to have a short circuit somewhere. that's what it sounds like to me. Unless you have a huge sound system with some 15" woofers in the trunk you shouldn't be experiencing any power shortages.

Here is the diagram.

did you give it a tune up change plugs fuel filter

Most of these pullyy pullers are universal check with a tool supply company snap on mac matco cornwall info should be in your phone book
