Vehicle starts then after a very short period of time just a few seconds. It has spark, the fuel pressure is good as well as the compression. I have replaced the spark plugs, ignition coil, idle air controller, oxygen sensors, injectors, and temperature sensors. MAP sensor tested fine. Does not show any codes. Any help or ideas on what to look at next would be much appreciated because it has me stumped.
