???VATS deleted car ran all last year now dies after 3 seconds???
Story goes like this..
Did my swap and ran it all last year, was running the stock ecm, kept the body control module and made a OHM plug for the key chip to be able to avoid deleting the VATS. Ran fine all year. Now I finished my turbo kit, sold my stock computer and ordered one from spare ECM with VATS deleted and a bunch of other stuff that I didnt need. I did this so I would only have to rewire once and try and save some time for myself. I didnt want to have to rewire again after the tuning for the turbo. So I get the wiring done, car starts right up and dies, standard sign of VATS. I call Spare ECM tell them whats going on, send in my ECM so they can fix it. They say it was tuned out and fine and charge me for both ways of shipping. Already angry about it, but still dont have an answear to why it is cuting off after 3 seconds.
any input, or other experiences with similar issues?

How about the power sources to the PCM.. Battery hot and IGN Hot. I know other have had issue when connected to the wrong IGN connection. The key when switched between Start and Run would cut out. something to check.. making sure the IGN stays hot in both Start and Run positions.
Back to checking everything. Maybe have someone local check with EFILive or HPTuner to check the VATS.. also monitor the fuel pressure ?

Thanks for the replies,
not sure about the oil pressure feature. Honestly havnt heard of that before.
as far as the ign connections I'm pretty sure I have it all right, I even did a bypass to make sure they were all getting power full time and it still did the same thing. I am about to head out there and recheck all my wiring. I kind of want to wait before I change anything if I do and plug in the ECM as soon as I get it back. If it fires right up and stays running then they fixed the VATS and didnt tell me. If it does the same thing, then its something on my end.

got the ECM back put it in the car same exact thing happened. I started thinking about it and when he told me they put it in a car that still had the VATS enabled, that means the body control module was still in the car and thats what sends the signal to the ecm. Of course it would still run because its getting the signal sent to it.
Does anyone live in the Detroit/Royal Oak area that would be willing to let me put the ECM in their car to test it??

I think you best bet would be to have someone check it with ether EFILive or HPTuner.. I have read of other having issue where they were told and thought that the VATS was disabled in the ECM.. but it was not or something else was needed.
You might try another mail order tuner !?.. I had used Wait4meperformance before.. cost was not bad.. ($85) but I am sure someone local might be your best bet.
