Why wont my 1999 sable start?


If you sprayed something into the intake
I would assume you were checking for fuel

So is the fuel pump coming on?
Is the there fuel pressure at the rail on the motor?

You check for OBD Codes?
Look at any scan tool data?
Have injector Pulse or clicking?

Testing one spark plug is not a conclusive test of much
How was that test done?

You checked ALL Vehicle fuse?

Battery any good & was that tested?

Check cylinder leak down or compression at some point

My hino dutro 616 2008 model has been cutting out at times, go into crawl mode. When you turn the truck off for ten min it drives again like normal. Sometimes it goes for weeks on end without any problems...


Sounds like A Fuel blockage, check pickup in tank and filter on side. Of lift pump bolted on injector inside the bolt holding the fuel line to inlet side. And blow air back into tank. An accumulation of particles will cause a blockage when fuel is moving and then disperse when the fuel stops moving. .

1999 Malibu hard start in hot weather, after it starts runs great lots of power. starts when cold in cooler weather.V6 3.1 engine. have gas at rail. changed spark plugs and wires, IAT and ECT sensors also...


this is most likely a fuel vapor issue.

fuel boils in the fuel rail causing a hard start after a 'hot soak'.

the fix is to replace the fuel pressure regulator and the pcm. good- day !!

My 2004 dodge 2500 diesel is always hard to start in cold or warm weather worse in cold weather.will start if i use either.I've put new relays,new heating coils,(glow plugs),and still doing it the code...


If the motor has common rail injection it doesn't have a conventional injection pump but it does have a high pressure pump and if the pressure is slow to build due to air leaks, drain back or wear then injection will not begin until the rail pressure is sufficient.

If there is a conventional injection pump it can still suffer similar maladies but will not be capable of generating such expressive codes.
Codes incidentally, often indicate a relay or sensor or something has a fault, though that isn't as simple as it sounds and a code read is only a small step in a diagnostic process. Often it is just as likely the circuit that has the fault - wiring, connections or the ECU itself. Sometimes a fault code is an indication of a fault elsewhere. Other test equipment should be used to verify the fault code and no component should be replaced until it is found to be faulty using independent testing methods and when something must be replaced the circuit should be tested and success verified before moving on to the next stage.

Basics first is the best practice rule and in addition to the obvious basic stuff it is worth noting a good cranking speed is essential and the injector spray patterns and pressures should be tested and while the injectors are out being tested/overhauled why not do a compression test...

98 chevy suburban engine turns over but wont start.


I'd Start With Checking The Spark Plugs, This Can Be Done By Pulling Them Out And Setting Them To A Ground And Trying To Start it Result Should Be Spark Obviously. With The Cold Weather Involved Id Try Cleaning My Valves If You Wanna Go The Easy Way Buy A Can Of Fuel Additive Injector Cleaner And Run It through A Full Tank Of Gas.
