My 1990 lumina starts but when you give it gas it acts like it dies but when you let up on the gas it comes back. i have changed the brain box, the eec, and the exhaust senser, nothing worked.


have you replaced the map sensor or try unplugging the map sensor and see what it does also check the vacume hose or conection to the map sensor also try unpugging the throtle position sensor with either one unpugged you wont be able to drive it but you can see what it does parked

Car running rought when u press the throtle there is a nocking noise i think this is the nock senser if i take the ht leads off the spark plugs 1 at a time starting from left they all make a nocking noise...


If you're getting ticking-type knock, I'd first look to the lifters. if it's a real hard knocking, it could be your main bearings on the lower end

Where is the valve for the freeon on a 94 buick skylark?


Try looking for a can-like looking 'accumulator' receiver dryer.
It will be aluminum in color and have a quick connect valve on it. This may also have a blue cap on it if it hasn't been lost over the years.

The tube from the r134a refrigerant goes here when the car is running and the a/c is set on its coldest position with fan on high.

Good luck.

WON'T START ENGINE JUST TURN OVER JUST CHANGE SPARK PLUG ROTOR DISTRIBUTOR CAP / SPARK WIRES


My first guss would be a fuel pump, just would have to verify that when you first turn on the ignition to crank you can either hear the fuel pump turn on in the tank or not, if you cannot hear the buzz or whine noise from the pump in the tank you need a fuel pump. Fuel pumps are a very common problem with these trucks.

94 lumina will not start after getting warm. will turn over but fuel injectors dont work. works during cold weather but not in hot weather.


The check engine light should be on with the engine running. The coolant temperture senser may be open at some temps the fastest way to test this is to change the senser ( it's cheap and a high failure rate part all auto parts stores will haveplenty of this high failure part in stock and they fail many ways. If the car ever overheated it's damaged or truly bad. A very good one will optimize fuel mileage so if it's suspect change it anyway as money well spent a working but wrong senser can cost alot of gas on any fuel injection car or truck, You get what you pay for in temp sensers and the brand name ones are better. All of them are suspect to be bad even when new and ohm test at temperture charts are is repair manuels. Crank sensers and cam sensers also get hot and quit they cost more are harder to change and fail more on the 3.8 motor than the 3.1 or the 3.4. Igiton modules do this too but it sounds like its been doing this awhile and modules and crank sensers don't stay half bad very long. they stop altogrther. Temp sensers can stay bad and work wrong. If you can get a scanner hooks to the car on data stream the senser may show room temp when cold but as it heats up goes up then to -34 thats open the system doesn't know that to do as the air charge temp senser doesn't agree and the system fails to start and will check as flooded. Flooring the gas and hoding it there may start it anyway. The trottle position senser were to show open thats the clear flood mode and the injectors won't fire. Tps voltage should show .5 volt les than 1 volt at idel (it'll start) and 5 volts at full throttle or nearly. if it shows with a scanner of a voltmeter on the center wire 5 volts or 0 it won't start. Coolant senser fails more often and is cheaper
