If you've already replaced the water pump and thermostat and the battery, there could be a few other reasons why your 2017 Buick Envision won't start:
Fuel delivery issue: There could be a problem with the fuel pump or fuel filter, causing the engine to not receive enough fuel to start.
Ignition system issue: This could be a problem with the spark plugs, ignition coils, or the ignition control module, which could cause the engine to not receive a spark.
Engine mechanical issue: If there is a problem with the engine's internal components such as the pistons, bearings, or crankshaft, the engine may not start.
Computer/electrical issue: The car's engine control module (ECM) or other electronic component may have failed, preventing the engine from starting.
It's recommended that you have a professional mechanic diagnose and repair the issue with your Buick Envision. They can use diagnostic equipment to determine the cause of the problem and repair it accordingly.
no problem told just hunt. sad no?
other answer is for new car Airbox = air cleaner box.
and is wrong.
3.3L GM V6.
most old cars ECM is in passenger compartment far cooler than near any engine, and back then that was true. (hot ecm have shorted lives)
no it is not at hood air box, 1991,
IT IS PNP. (no programming but has a PROM pack)
ACTUAL 99% SENT IN ARE GOOD. INPUT SENSORS BAD. or output actuators bad or 50 other causes and 20 + tests to find them.
here is the real answer and told at Fixya
The ECM is mounted on the right side of the dash above where the passengers feet would be.
The lower panel will need to be removed to see it.
Here is the service manual procedure to remove it.
Turn ignition to "OFF".
Disconnect battery ground cable.!!!!!!!!!
Remove right hand hush panel.
Disconnect connectors from the ECM
Remove ECM mounting hardware.
Remove ECM from the passenger compartment.
Remove ECM access cover.
Transfer PROM unit to replacement ECM. Using two fingers, push both retaining clips back away from the PROM. At the same time, grasp it at both ends and lift it up out of the socket. Do not remove the cover of the PROM. Use of unapproved PROM removal methods may cause damage to the PROM or socket.
t sounds like there might be a short circuit somewhere in the electrical system of your 1986 Buick Riviera. This could be causing the battery to drain and the dash lights and interior lights to behave abnormally. I would suggest checking the wiring and connections in the car to see if there is any obvious damage or loose connections. It may also be helpful to use a multimeter to test the electrical system and find the source of the short circuit
When a vehicle is coasting and slowing down it will often switch into a lower gear which will cause that "back pulling" sensation, as the lower gear is now slowing the car down, which will also cause the engine speed to increase, which you might believe to be engine hesitation. That's the way they are supposed to work, unless of course you have switched the transmission into neutral, which is not a good idea to do.
could be gas cap missing or not tighten is usually the first thing that can give an evap code ---you can probably have a leak from hose cracked or not seated correctly to a damaged component -------https://www.autocodes.com/p0455_buick.html

To check the engine codes on a 2007 Buick Rainier without a scan tool, you can retrieve them using the following steps:
Turn the ignition to "On" (not start) position Locate the "Data Link Connector" (DLC), usually found near the driver's side kick panel or under the steering column. Connect a jumper wire to the DLC terminals A and B (consult the vehicle's manual for the correct terminals) Turn the ignition to "Off" position Turn the ignition to "On" position, but do not start the engine. The check engine light will begin to flash, with the number of flashes indicating the first digit of the code. For example, if the light flashes three times, pauses, then flashes four more times, the code is 34. Repeat the flashing sequence two more times to retrieve the second and third digit of the code. Write down the code and refer to a manual or online resource to interpret the code and diagnose the issue. Note: This method may not be applicable for all vehicles and some vehicles may have different methods for retrieving the codes. Always consult your vehicle's manual for the correct procedure.
the VIN code 8th digit shows this
the RPO tag on all GM shows the 3 digit engine code.
I guess the question is what engine is in my car,?
USA car 2001 gen 6 car, had
If the cruise control on your 1997 Buick LeSabre is intermittently working, there are a few potential causes that you can check:
Vacuum leaks: The cruise control system on your vehicle uses vacuum to operate, so if there is a leak in the vacuum lines, the system may not work properly. Check for any visible leaks and repair them if necessary.
Throttle position sensor: The throttle position sensor (TPS) sends a signal to the cruise control system to tell it the position of the throttle. If the TPS is malfunctioning, the cruise control may not work properly.
Servo Motor: The servo motor is responsible for engaging and disengaging the cruise control system. It may be that this motor is faulty or that the gears inside the servo motor have worn out.
Speed sensor: The speed sensor sends a signal to the cruise control system to tell it the vehicle's speed. If the sensor is faulty, the cruise control may not work properly
Vehicle Speed Control (VSC) module: This module is responsible for controlling the cruise control system. If it's malfunctioning, the cruise control system will not work correctly
It is highly recommended that you take your vehicle to a qualified mechanic to diagnose and repair the issue, as cruise control systems can be complex and require specialized knowledge and equipment to diagnose and repair.
check level and examine trans fluid if smells burnt or is brownish can try filter and flush ---if same possible torque converter --valve body -or gear -clutch pack which you would need a trans shop to assist in diagnosis
The main power fuse on a 1985 Buick Electra is likely located in the engine compartment fuse box. The fuse box is typically located near the battery and can be found by following the positive battery cable.
If you are having trouble locating the fuse box, consult your vehicle's owner manual for specific location and a diagram of the fuse box layout.
The main power fuse, also known as the "battery fuse" or "fusible link," is responsible for protecting the electrical system from damage caused by a power surge or short circuit. The fuse is usually a large, cylindrical fuse that is located in the main power distribution circuit. It will be the largest fuse in the box
Once you've located the main power fuse, you will need to remove it to check its condition. If the fuse is blown, you will need to replace it with a new one of the same amperage rating. It is recommended that you use only fuses that are specifically designed for your vehicle, and that you consult your owner's manual or a professional mechanic for the correct amperage rating.
It's important to note that working on electrical systems can be dangerous if you don't have the proper knowledge, so if you're unsure about how to proceed, it's best to consult a professional mechanic.
SOLVED!!!!! Both of my rear doors stuck shut, wouldn't open from outside or inside, the locks seemed to be working properly. After scouring the web I found a post explaining a design flaw was responsible. If the doors were unlocked while someone was pulling on the door handle the mechanism would get stuck. I was able to get the inner door panel removed without breaking anything, only the backseat bottom needs to be removed. It takes some finesse to get the bottom clips undone but IT IS POSSIBLE. Once I had the door panel removed I was disappointed that pulling on the lever from inside wasn't working to disengage the door. Finally I recalled the post that explained why so many people were experiencing this issue with the cars. I reversed the action that caused the issue to begin with, pulling the lever thats connected to the door while holding it I unlocked the door and it finally disengaged. I will post of video when i get around to the other backdoor
replaced deterrent system on ignition replace battery new alternator can't get car started ???? Your a parts changer not a technician . Do yourself a favor an take it to a qualified repair shop , one that know's to hook up a factory or some other type professional scan tool an check for DTC'S - diagnostic trouble codes in the theft deterrent control module . An after changing the module it needs to be programmed . DEALER
