About half a year ago i was driving and my car started choking and it stopped on me, I had to call a tow and had it tow home. A few days later i tried to turn it on again and it started.
I then replaced the fuel filter and used seafoam to help clean up injectors, fuel lines etc.
Yesterday about half a mile from home, my car does the same behavior again, started choking and shut off on me.
I was suspecting it might be the fuel pump so i checked the fuel pressure with the Torque app and i have fuel pressure so that makes me think its not the fuel pump. If it was the pump, i would think i would have no pressure.
Any ideas what might be the culprit of this behavior?
To anyone else reading any of my posts I usually include the line: Today's cars simply will not run right without a strong battery and charging system! Cut corners here at your own risk I'm a big believer in starting with the basics. As such I...
Regarding a possible fuel system problem, why guess? Test! Any problems with fuel flow will show up in the STFT and LTFT's as well as the fuel pressure.
While working on your car have you ever wanted: to find an ODB2 operational PID value (say fuel pressure or MAF)? How about graph a PID value over time? Or compare multiple PID's over time? Access a bi-directional PCM control such as test a...
Another easy way is to look at the check engine light during cranking. When the key is on, the check engine light should be on. The check engine light should go out during cranking. This indicates the PCM is alive (at a basic level) and is receiving a CKP signal.
