stalled while driving
Hi everyone i am a newbee to this forum and i really need help from you guys to help me solve this problem. I started my 2006 is250 a day after driving through some snow and slush, and it fired up good as all other times, before i could reach 1/4 mile from home the engine instantly lost power and stalled and would not crank over, i also noticed the transmission P R N D position shift lights on the dashboard were all off when the switch was on and my scan tool have stopped communicating with the ecm, i have checked all fuses in and out and everything thing else powers up.The starter button turns to green when i press the brakes and the other lights and guages function normal and it still wont crank over. After a new battery and 3 weeks of being down i got into the car yesterday pressed the starter button and saw the the gear position lights was lighted up, i pressed the brake and the starter button and the engine cranked over and stopped with the position shift light going blank and the starter going dead again .Please i neeeeeeeed some help to get my car running again.

You may need to look it to a full pressure sensor issue. Lately there's been many early model 2IS with this issue. Many threads on this floating around. You can check the fusible link also. Since you changed batteries you could have inadvertently shorted it out. It doesn't take much to make it blow the fuse.

Thanks for the response but would the fuel pressure sensor cause the starter not to turn and the transmission position indication lights to stay off? The alternator was removed and it was tested by a reputable technician and found to be good,I am really lost on this problem

Hi mikeFig82 you were so correct about that info, I disconnected the fuel pressure sensor connector and the engine is able to crank over and the selection light is back on, the motor did not run but I guess it will as soon as I replace the sensor. I will keep you in the loop thanks again.

That's cool. Yeah it sucks trouble shooting stuff LOL. There is a PDF you can download on the procedure to install the sensor itself. You can find it on the links that have already been posted by other members. It seem to be happening more frequently on early models lately.

Some tips if you don't have a fancy diagnostic tool. Use a hand held meter...
Same thing is happening on the 2IS series as we speak. The 06 - 08 crowd. That said they are replacing the sensor.
Like the video, unplugging the sensor allows the car to start.
Good find.
Note to those trying to troubleshoot (TS) this: Using engine ground and the data wire, not the 5v supply wire, one could TS this with a volt meter by back probing the data wire and reading the voltage. Engine off the pressure leaks down and with the key on one might see 0.5v. When running expect something north of 2.5v and to increase as RPM goes up.
Hint back probe is to use a very small stiff pointed probe to shove through the moisture proof connector. Again, us common engine ground for ground.

If the sensor is good, the voltage will rise. If the sensor is bad it will be unresponsive..
