Check the ECM for this number on it. 1228253 these ecms are junk. These would do that cutting off and restarting. They also made the car speed up to about 30mph without pressing the gas pedal. Replace with 16198264 or newest number. My car did the same thing. Having worked at a Buick dealership from 1988 until 2007 I have seen many of these replaced.

2005 Suz. Swift The engine light blinks when I am driving, then my car will sputter, and stall completely. I usually can shut the car off and turn it back on and it will run. What's wrong? Thanks!


blinking check engine light means -requires immediate attention the computer found a problem with vehicle that can cause damage if continued to run or drive --some codes will shut down vehicle to a limp mode or the problem can cause shut down ----have code read most auto stores offer this for free the code will give you a start point towards repairing your vehicle

I have a 1990 5.8 liter ford bronco. When engine is cold it will start immediately. Once the engine is warm and driven a short distance. Engine will not restart until engine cools.

Starting problems


It will likely be the crank sensor, usually fitted next to or behind the bottom engine pulley. A common failure is for the sensor to stop sending a signal when hot, and the engine will stall immediately. After a time, it re-starts but will cut out again when the sensor gets hot again. These sensors are easy to find and replace, and not usually expensive.

Car dies intermittently


THIS ONE IS EASY. CHECK YOUR BATTERY TERMINALS AND CABLES THAT THEY ARE TIGHT. IF THEY ARE, YOUR BATTERY MAY NEED CHARGING OR YOUR ALTERNATOR IS NOT CHARGING YOUR SYSTEM THAT WELL. I WOULDNT DRIVE LONG DISTANCES UNLESS I HAD THAT CHECKED.

Car starts then will shut off


The first thing I would check with the limited information that you gave, is to have the fuel filter changed if you haven't done so. We need more information to diagnose other problems, including engine size, etc. Hope this helps you, Rick
