Did u try cleaning the TBD? had the same issue and no one was I able to fix and eventually I did it (thanks to the guys on this forum) with a toothbrush and a TBD cleaner for less than $10

 

Hello

I also tried it, the problem in this case is that you can drive a very long time without problem. When the vehicle stands and runs on idle for about one minute, is at once extinguished, it only starts with full throttle. It is not necessary that always goes out of 100 attempts, 8x extinguished. Then again function normally as long as one week. The TEC 2 is only observed change in pressure in the pipes for gas, shutting off the fuel pump. In the next experiment, the relay and the pump operates normally.

Thank you

 

Water in your gas?

 

I think the 08's need 93 octane 6.2 litre vortech?
