We have not been able to get the new engine to start and run. It keeps going into lock mode and we have to disconnect the battery and start again. I did manage to connect to the PCM but got no codes. The engine will start and quit like a security relearn is needed but the security light is not flashing and the PCM has not been changed. The friend, who is a mechanic, did the install but is not strong on solving these kinds of issues. I was wondering what the problem might be and how to tackle this issue. One thing is that he has his large battery charger attached to keep the battery up and I am wondering if that might be interfering with the process. If anyone has any incite to this problem or advice I would be grateful.

We do have fuel pressure and I assume spark (but will need to confirm) from the way it runs for a couple of seconds.

Then he gets the flue so it is held up till tomorrow.

Thanks guys

 

I dont know how HPT is, but in EFILive you can turn the VATS system off, I woudl try that just to rule it out. Also you might try posting this in the general section since it could be something un-related to tuning and also gets more traffic.

 

mine did this on a vcm swap. it was a security relearn afterall so maybe just give it a shot?

 

yep you can turn off the vats threw HPT.

 

Thanks guys. I have Tunercat so I will look to see if I can turn VATS off.

I see it has a Switch called,[ ] VATS Fail-Enabled Option [X=Enabled] and it does not have an X so it is disabled. Looks like the VATS is already turned off. Is that how you read it?

I will try a security relearn again but maybe I should enable VATS again? It is a little hard when the security light does not flash and there is no indication if anything is happening.

I will try the general section too, Thanks slow!

 

x = enabled and no x i would say its disabled, what condition is the injectors? have they been sitting for a long time, just a thought might wanna check and make sure they are all clean but it does sound like it needs a relearn

 

The truck has only been down for a 4 days to do the swap so it has not been sitting for too long. It seems strange **** always happens when things are taken apart and seemingly but back together again correctly.
