08 toyota tundra no ecm communiation no start. Has no ses light no communication with ecm. Car cranks but doesnt start No communication with ECU. I need some help.

If the engine is failing to start entirely that can be a symptom of a bad ECM. Posted to Asian Driveability on 1162012 6 Replies. Some 2007 2008 model year Tundra vehicles may exhibit a no start condition with Diagnostic Trouble Code DTC B2799 caused by water intrusion into the engine room wire harness.

Im having the same issue with my 08 No connection when brought to the inspection station. A bad fuel pump ignition problems clogged fuel filter bad mass airflow sensor and bad crankcamshaft sensors are just a few of the problems that can cause an engine to not start. Any suggestions before I by a new ECM.

No communication possible with the replacement ECU no check engine light with key on and no fuel or spark. Since you have a 2001 Tundra the communication protocol is ISO-9141 which uses just pin 7 K line for bidirectional communication with pin 5 as the signal GND pin 15 the L line is not used or required and there is no copper connection present. Cant find the spark plugs on a 2004 toyota tundra V-8.

I tried using a re-manufactured ECU that was programmed with my VIN I also tried using a junkyard ECU when the re-manufactured unit wouldnt communicate. If not do the same with crank sensor. Once towed back home found that their was no fuel pressure.

I was also wondering if I can fit any ECM that is a 4x4 57 2007-2013 will fit my 2010 DC rw 4x4 57 tundra. Tundra Solutions Forum - the best.
