2003 saab 95 Aero - stalled...can't get it started

Did you try to start with start spray or propane!? Can be injectors?!

I see no one else has posted an answer for you here yet so I will take a stab at it for you. The P1300 codes I am familiar with on the Saab's are P1334 and P1312 which almost always means the ignition cassette is failing. Most of the time the car will still run good, at least at first anyway getting worse over time. They are not cheap, ebay has the lowest prices and most availability that I know of. They are very easy to replace, just one electrical connector and four large torx screws right on top of the engine. If you have a black one replace it with black, red with red. To be absolutely sure you get the right one it's best to match part numbers. That being said most of the ones I have used have been interchangeable as long as they are the same color & # of cylinders.

Here is what I could find on it:

P1300 Random Misfire Detected. Catalyst Damaging.

Chances are that the Saab Ignition cassette is failing. You can find them on ebay, I recommend a new one since it is a common failure. Best to put new plugs in it while you are at it.


Easy to change, you just need a T-30 Torx (4 small bolts)
and one electrical connector on top of the engine. Oh and a good spark plug wrench.

Number 3 cyl is third from drive belt end of engine.3rd from left as you stand at front.Change DI cassette,it's cheaper and quicker.

spark plug misfire, check your plugs and wires for burn marks or fowled...

Hello
The engine and automatic transmission in this vehicles drive train are fully electronically controlled by a computer called the PCM (Power Train Control Module). Whenever a problem like this occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM

The P0304 indicates the #4 cylinder is misfiring. The flashing light means the cylinder is not firing at all...It could be several things causeing it, coil, wires, plug, injector or vacuum leak. Do not drive your vehicle until you have this repaired, as it will lead to further more costly problems. Good luck, i hope this helps.

Most likely the coils. Easiest way to check is swap them with another cylinder, start it, pull the plug wire connecter and if it doesn't change the engine the coil is bad. If it is the injector, then you can check it with an ohm meter. Touch the leads in the injector it should read 11 to 15 ohms. if you need help let me know.

Have you check the O2 sensors? How baout cleaning the MAF and Throttle body? Thermostat?

How does the temp gauge look whn it stalls?
