Everyone is missing the main thing here, you just WASHED the motor. You got water in the ignition system. It would be helpful if I knew which motor you had, 2.3, 2.5, or 3.0. If you have the 2.5 or 3.0, you should remove the distributor cap and spray some WD-40 in it, let it dry, and reinstall. WD-40 was a military invention, and the name stands for Water Drier-40th formulation. It was designed to displace water and lubricate to prevent rust where the water was. If you have the 2.3, you will have to remove the 4 bolts that hold the cover on the top of the motor, unplug the electrical connector at the end of that cover, and lift it straight up off of the motor. Underneath the cover you will find what they call the coil cover. This actually acts as your spark plug wires, distributing the energy from your ignition coils (there are 2 under the coil cover) to the spark plugs. There are 4 "boots" that probably stayed on your spark plugs when you pulled the cover off, you will need to remove them from your spark plugs and put them back on the coil cover when you are ready to reinstall it. You will find 6 VERY SMALL BOLTS holding the coil cover on the main cover, remove them and the coil cover will easily come off. Dry the inside of this as stated above with the other 2 engines, allow to dry, wipe it out and return it as you removed it.

SOURCE: 1991 Olds Bravada 4.3 v6 rough idle and backfiring.

Ok guys, let's fix these things here!
Just went through this myself, so do the following:
Go to your local parts store and buy a Haynes Repair Manual.
You need to read the book first, learn how the ECM (Electronic Control Module) works. You'll see that there are alot of sensors and components that make up the fuel emissions bologna.
The nice thing about this system is not only does the ECM control all electrical functions, it also trouble-shoots it's self. When a component or sensor goes out, the ECM stores a code for that event in it's memory. You can use the Haynes Repair Manual to put the ECM into diagnostic mode and thus read any codes present.
So, all that's left is replacing what the EMC tells you too! :) Good Luck!

SOURCE: Car was running fine, now won't crank. It turns over. Some told me timing chain, distributor, injectors, spray carb spray in throttle body or something like that. Can you please help me?

You are saying that the engine will crank or turn over but will not start? If so then you must fine out if the engine has both fuel and spark. after that you can get into the right direction. You can use starting fluid to see is there is a fuel issue. Read the directions on the can. Using too much can harm you and/or your engine.

SOURCE: 2000 alero stalls when coming to a stop.

ENGINE STALL DUE TO FUEL STARVATION: Fuel System, Gasoline** CLOSED no recall issued
** This defect investigation is filed under 4 related vehicle components.
2000 OLDSMOBILE ALERO -- ODI opened PE02-066 to evaluate the scope and consequence of engine power-loss due to fuel starvation induced by in-tank modular fuel pump strainer restriction.the subject pumps use an external ?sock? strainer to filter fuel flowing to the pump inlet.this filter can sometimes become clogged, resulting in a reduced flow of fuel to the engine.GM has subsequently modified the strainers to reduce this restriction.analysis of the ODI complaint database shows that despite these restrictions, the subject vehicles stall at a rate that is comparable to those of many peer vehicles.additionally, none of the relevant warranty repair rates exceed 1% at 36 months of related crash involves a stalled vehicle that was rear-ended on the roadway, while the remainder involved minor collisions or scrapes.the sole injury consisted of bruising from a low speed frontal crash. Given these circumstances, further expenditure of Agency resources is not justified in this matter.the preliminary evaluation is therefore closed.the closing of this investigation does not constitute a finding by NHTSA that no safety-related defect exists.the Agency will take further action in the future if warranted. Investigation was initiated on September 06 2002. Closed on November 03 2003. For detailed information & supporting documents, see the official

86 olds calais only starts if i pour fuel in throttle body fuel pump is working, is their a fuel filter by the throttle body or could it be a relay

The fuel filter is under the car, in-line. If the pump runs, it wouldn't be the relay. When you try to start it, can you see any gas spray from the injector? You could have a bad injector. Check for power going to the injector.

1988 Cutlass Calais. Motor runs fine on start up.

Sounds like the veh is loading up on fuel make sure coolant sensor to computer is reading right it could be choking the car.Also check for clean throttle body But what the most likely cause is the mass air flow sensor. Blow it out now do this gently there is a wire in there thats what you want clean. dont spray any liquids on it THANK TIM

Replaced fuel filter & fuel pump and screen.

not positive but in the air breather there is a mass air flow sensor and sometimes air filter particles gets stuck on the sensor.It will look like a white piece of lint,if there is be careful to remove it and try it.Usually a backfire and sputtering is the signs
