SOURCE: starter relay
My daughter's 99 SL2 had the same problem and I went through all kinds of gyrations trying to find the starter relay (HATE working under the dash!).
As you are sitting in the driver's seat, put your left foot even with the brake pedal and move it as far to the left as it will go. It should now be against the kick panel. The relay will be about 12 inches above. It's wrapped in electrical tape onto a wire bundle, so you'll have to cut away some tape to get to it. The hardest part isn't changing it out, it's finding the #$@! thing.

You mentioned that some of the couplers for the intake runners are (were) split. I don't think that has anything to do with your problem, but it gives me an idea.
If the vacuum hose leading to your MAP sensor is also split/crushed/broken then the MAP sensor will never register any manifold vacuum. The only time that reading would be right would be when the car was at WOT. This theory alone does not explain why your car does not run, though because your car also has a mass airflow sensor. It should be able to run if either one of those sensors fails (but not both - or at least not very well with both failed). Did your car display a "check engine" light before the current condition developed? Does it have one now?
I would check the hose leading to the MAP sensor (if there is one - now that I look more closely at the drawings, it doesn't look like there is a hose). The MAP is on the top of the intake manifold on the rear bank above the cylinder closest to the driver's side of the car. It is held in by one bolt.
Can you retrieve any stored codes? Stores like Autozone will scan a car for its codes for free, but they don't make "house calls."
After typing all the above information, something new has occurred to me:
Your car has a drive-by-wire throttle. Idle speed is controlled by the electronic throttle valve. If you remove the tube that connects the throttle valve to the air cleaner, you should be able to see the throttle plate. Does it move appropriately for the amount of accelerator pedal input? For example, if you apply roughly 10% throttle, does the plate open roughly 10% of the way?
Your engine computer may just need to re-learn the position of the throttle plate. To do this, with your foot off the accelerator, turn the ignition to the "run" position, but do not attempt to start the car. After 30 seconds, the engine should begin the relearn sequence. If there are any TPS-related codes stored, the ECU will not attempt to run the relearn sequence, so you'll need to diagnose why that isn't working.
Anyway, this second option fits your symptoms a bit better than the first, and could indicate a failed throttle position sensor, accelerator position sensor, throttle actuator, wiring, or engine computer.
By the way, inability to rev above 3200 RPM may not be a problem. Some cars with automatic transmissions are limited and will not rev above a certain speed when in neutral or park. That said, if the throttle valve was not opening all the way because it was faulty, that would be a different story.

1st, There is a relay in the PDC, marked for starter, pull the relay out and swap with a relay beside it, if it works, bad relay. 2nd if not relay , remove and check pin no 30 with test light, should have power, straight opposite is pin 87 that goes to starter, jump these two pins and starter should crank over,if ok. 3rd, check pin 85, comes from nuetral safety switch, test with test light, pos batt to this pin 85, light should be on, if not you have a problem in that circuit or switch. 4th, pin86 comes from the igntion switch, yellow wire, in crank mod this pin 86 should light up with test light, if not, you have a problem with that cicuit, to switch, possible broken wires in collumn connecter to switch. GOOD LUCK RDJRP

If the starter/Battery are ok.Check for spark by pulling off a sparkplug wire,have someone try to start hold wire near sparkplug tip you'll hear the spark jump to the plug tick..tick..tick..sound.Be carefull to hold wire just far enough to hear spark,also this is the secondary circuit from the coil it's high voltage wear a glove.If you smell gas youre geting gas if no spark it is 1 of the following.Bad Coil, or ignition modulator, crack in distributer, cracked wires that cause spark to not reach plugs.Good Luck.

The gear reduction starter on this motor has a pattern failure of the solenoid contacts that transmit the voltage to the starter brushes. There is a repair kit available for replacing the contacts or you might just change the starter with a rebuilt unit. Intermittent function is almost always this problem.
