08 Toyota Tundra No Ecm Communiation No Start

If the engine is failing to start entirely that can be a symptom of a bad ECM.

08 toyota tundra no ecm communiation no start. This truck died while driving no start spins ok no ses at all when I check with the techstream ecu will not respond. I need some help. I wanted to get a second opinion or to see if anyone knows where I can get good prices because I know the 1189 they quoted me for a new ECM is wrong.

And I had taken it to a shop who suggests a new ECM replacement. All lights was still on and ac power steering lost and hard brakes accelerater pedal went to the floor. Now it only cranks not starting.

Try lightly slapping the ECM with your palm and verify that all the wires are plugged in securely into the ECM. Posted to Asian Driveability on 1162012 6 Replies. Hi got a 2012 tundra 57 crew max.

All i did that day was pull some wires through the firewall including a 4awg power cable i also am putting two 16awg wires into the fuse box for future fused switches. But didnt want to do the work to get to it and now its back at my house. Died while driving spins ok no start.

Checked all power and grounds to ecm. Replaced the ECU but the truck still wont start. Once towed back home found that their was no fuel pressure.

I checked all the fuses and were all good. Also no communication to the computers was present. All relevant relays are working EFI starter circuit openingfuel pump fuel pump is working spark test shows coils are firing on crank fuel is getting to rail fuses look good.
