Vehicle Shuts off twice?

Yep, this can be many things causing this, but I need to ask you a few questions to get started. First, does the car go dead, meaning all electrical in the car stops? Next, does the engine sputter and then stall or does the engine stop instantly at the stop? Next do you have a check engine light on? And lastly how old is the battery in the car? We need to isolate the system that is failing. Here is a video to help run the codes so we can get started.

Hello Ken,

Thanks for your reply!

When the engine cuts off, it happens when I'm in stop-and-go traffic (under 20mph), and when I press the accelerator, the engine cuts off completely, no sputtering, but the dash lights are still on as if in the "acc" position when starting the vehicle.

No check engine lights on, although I did have one on previously that went out, the code was P2A01, rear O2 sensor I believe.

The battery is an 85 series with a manufacturing date of 5/23.

I had scheduled maintenance today, and my mechanic could not find anything with the code reader since no lights were on the dash. Oil change was done.

The video with Ryan was a great help by the way!

Thanks for your assistance!

Thank you, it sounds like the battery might be okay but you should have it load tested incase it is bad. the P2A01 - O2 Sensor Circuit Range/Performance Bank 1 Sensor 2 will no make the engine stall. So we are the base steps, when it does idle is the engine running smooth? if not you can have a vacuum leak, if not the problem can be the MAP or crankshaft position sensor, I have seen the ignition switch cause this as well along with the main and fuel pump relay. Lets start with the easy stuff, when you have driven the car for a while check the fuel pump and main relays to see if there are warm or hot. Here are the locations. Check out the images (below). Please let us know what happens.

Hello Ken,

The engine runs smoothly when idiling, the other items I will check and get back to you, thanks.

Hello Ken,

The main relays are warm, not hot, same as the others in the compartment.

Thanks,

Roosevelt.

Yep, these is the toughest problem in car repair, with no codes we can go over the most popular items that will cause this, we will start with the easier stuff first, let stat with the crankshaft angle sensor which is by the oil filter and will no leave a code when it fails. Check out the images (below). Please let us know what happens.

Thanks Ken,

I 'll let you know.

Roosevelt.

Thank you have a good Sunday!

Hello Ken,

I took my vehicle to another shop for a diagnostic check, and all they said the problem was were fouled spark plugs and Fuel Injection was service needed.

They did the repairs and now the car is just fine!

Again, I'm surprised the shop I usually go to did not find this problem, it seemed to be rather simple. But anyway I'm happy the repair wasn't too costly, and the work was done in just a few hours.

Thanks again for your help Ken, it is greatly appreciated.

Roosevelt.
