Hi all! We've had a lot of questions about engine stalling and no-start problems lately, and the answers don't seem make/model specific. Let's put the questions in here, where owners of all makes and models can benefit from the answers. Thanks!

#2 of 460 Subaru Legacy -Engine rough starts and idles and stalls.
Mar 08, 2003 (10:44 am)
93-Legacy has slowly showed poor gas performance, even with tuneup, fuel filter changed,air filter change. Then this Winter, it started having hard time starting. I started to use anti-freeze and fuel injector cleaners as specified by the products. Now, the weather is a little warmer, my Subaru is worst. The engine takes long time to start, and runs very rough. It stalls when sitting in traffic. It indicates fuel system problems. Does anyone knows what I should do & what the cost would be to take care of this problem? I'm wondering if it's worth it to fix or buy something else. It has 177K mi.
#3 of 460 first wild guess would be fuel system stuff

like the gas line filter, pressure regulator, or fuel pump. if the filters have been regularly replaced (usual replacement periods are 50 to 60 thousand for domestics I'm familiar with), needs a fuel rail pressure test.
it might be injector clogging, but I don't know anybody who has clogged any. I'd go with wear-out items, and both the regulator and the pump are in the range in which they could be tired out.

Where Do I Start??
This article will help you have a starting place.
Then, read this article. What Do I Tell My Mechanic?
Reading these two articles will not only help you, but it will also help you to let us know the information we need to help you out.

my first guess would be electrical if the car will stall after it has been running for a while, and often idles rough. Generally speaking, if a car with a bad fuel pump has been running for a while, it will continue to run until the next time it is shut down, due to capillary pressure in the fuel line. Not only that, but a bad fuel pump wouldn't usually cause it to run rough.

What is capillary pressure in the fuel line?
Mar 10, 2003 (12:45 pm)
Alcan, isn't that how much pressure the heart of the engine can pump?
So where its the heart? Need to see if it is beating properly. LOL!

I'm still stumped by this recurring problem that my shop can't diagnose. Six months ago my '99 bonneville SE 3.8 V6 (47K miles) started stalling and restarting itself after 2-3 minutes from a cold start. When it finally started missing and threw a code I took it in. Shop replaced one ignition coil, full set of wires, fuel filter, injector cleaning, other assorted stuff for about $500. This fixed the problem for a few weeks. Problem started up again a couple of months ago and continues to get worse. No check engine light though. Now it is very hard starting, dies after two to three minutes. I have to restart it. Sometimes dies again two to three minutes in. Then runs ok -- a little rough but ok. Shop tells me they can't figure it out without a code. This problem is becoming serious and it always happens at the same time which makes me think it could be temperature or sensor related. Anybody come across this before?
#10 of 460 1991 Dodge Shadow undiagnosed engine problem.
Mar 19, 2003 (4:52 pm)
1991 Dodge Shadow with 70,000 miles and no significant problems before has begun stalling while on the road. After a few minutes, the car will usually restart, but I have had it towed once already. The mechanic mentioned it is a "California car" (purchased new from a Ca. dealership.) He has replaced the computer but that didn't solve the problem. He is out of ideas, and I am out of patience. Any suggestions? I like the car and wouldn't mind spending a little more $ to keep it.
