    Car has shuddered and stalled out twice in three weeks. Both times after driving for 40 minutes without any issues (fully warm). The said it was either the crank sensor or the fuel pump, but no diagnostic codes come up. they replaced the battery and that wasn't it after the first time I had it towed into the dealer.

Fuel problems are usually fairly consistent and not intermitent, replace fuel and filters anyway if it's near it's service interval. I think this thing is injected, but I doubt there is a problem with injectors ... again most fuel problems (unless it's the fuel pump) don't come and go.
Your username is dieselhuffer, in the states we don't have saturn diesels, so I am assuming your saturn is a gas engine.  I would concentrate on the ignition system,  ignition box, high power coil(s), wires (it's probably not these).  Buy your mechanic friend the Haynes (about $20 from amazon, parts store or haynes.com) manual for your car, and have him go though the ignition system diagnosis portion of the manual.  I'll bet you a pint it's an ignition problem.
The bad news, intermitent problems are hard to find.  The (sort of) good news is, it will probably get worse to the point that the thing won't run at all, making diagnosis much easier.  Hopefully you'll find the problem before you pull out much of your hair.
good luck,

Check the engine mounts. A friend of mine had a similar problem whereas acceleration caused a stall because the engine was rocking out of position.

I have a 2001 Saturn SL2 and I have a code that does not make any sense to my mechanic. PO341. Also PO442. Any help or suggestions?????


Hello ihatethiscom: My name is Roger and I will help you. The code p0341 Is for the camshaft position sensor There are several things that can cause the code. A intermittent engine misfire to a camshaft sensor problem. I always look for the simple problems first. A lot of people look at the sensor as being the problem not always so. As for the code p0442 this is a fuel evaporator system problem. This has several options when it comes to finding a solution. As I said try to look for the simple solution. A loose fuel cap can set this code also. A dirty fuel vapor canister or a cracked vapor line could cause the code also. What the code is saying is there is a small vacuum leak to the fuel tank. Should you need further help please just ask. Please rate the answer you received. Thank You for using Fix YA. Roger

It starts then it stalls, sometimes it starts right up some times it doesn


It could be the Crankshaft Position Sensor - My 1993 Bonneville with a 3.8 had the same issue, I replaced that and it works great now.
It had codes:
17, and 18 I think, or maybe 19 stored. Which was Cam Position sensor, and Crank position sensor problem.
The crankshaft position sensor is easy to replace, if you have access to a pulley puller, some tools and a jack or lift. Some motors need a special tool for an adjustable thing, but most dont have that anymore as I think they recalled it and replaced it on all.
I think they run about 30-60 for a new one, and takes about an hour to replace.
If it is intermittent start problem that may be it. Mine would start fine for a while, then sometimes after Id turn it off, it would just crank and crank, It would start after waiting about 5-30 mintues, while trying to crank it every couple minutes. When driving down the road, it sometimes would stall when turning or stopping.

2001 Saturn L200 start and stall


Have you done any component testing? U1000 is a data issue, cant read pulses per minute. This is usually due to a defective crank sensor but you should do component testing first so you don't replace parts on random. Other reasons for this failure can be faulty ignition switch cam positioning sensor, Blown fuse, bad ground, or ECM.

My saturn 2001 stalls at stop lights when in idle


your stalling problem could be the egr staying open a peice of carbon will keep it from closing easy to remove and check to see if the pintal is seated or a large vacuum leak will cause havoc with the idle system hot restart problem either the fuel pump or most likely quad driver module a sorry that one cost a few dollars

You can't afford to not take it to a Saturn dealer. Look at all the worry your going through not to mention possibly lost time from your job. I had the same problems with my 98 SL1. First time it went to the Saturn dealer they diagnosed a bad coolent tempurature sensor. The car was fine for about 2 months then it would start and then stall bfore I could get out of the driveway. This time the dealer diagnosed a bad crank position sensor. That was 3 years ago and the car has run well since. I believe your car could have one of these problems (maybe both). Take it to the dealer. They probably see Saturns with these problems every week and will know how to fix them.
