Need Some Help

[fleming442]

Okay, not quite LS, but close enough. 02 3800 Series II won't stay running.
- I don't think it's VATS. Allegedly, ZZ Performance disabled that, plus the fuel pump relay is engaged until after the engine stops.
-With the vacuum line on the regulator, 40-42 psi... unhook the vacuum line and plug it, 50psi
- Throttle pedal doesn't do much, if anything

Kinda lost. Any suggestions considered...

If it was the VATS it shouldn't start at all. If it did happen to start with existing fuel it shouldn't start again for another 4ish minutes.

I disabled the VATS in my wife's TA along with a BCM that was giving me problems.

Make a copy of you ignition key with a normal key(no chip) see if the problem continues or if the system is dead.

If it is dead with the non chip key the VATS was disabled incorrectly

LOL- key!
I jam the red and pink together, then touch the purple to start...

How long has it been sitting? Brother had the same problem with an engine swap, all the injectors were clogged.

Hmmmm, that's very possible.... I'll try to check it out. I think. How the hell do you check injectors?

Well the redneck in me has pulled them, hose clamped a hose on the injector output end, poured fuel injector cleaner in the hose, clamped my air hose onto the hose, then pulsed them with a 9v battery while applying 10lbs of air pressure. Yes, it looks as dangerous as it sounds.

This has worked for me on three different engines that have been sitting if the injectors are still good

With a D cell battery or 9 volt to see if they "click".

To make them spray, I rigged up a steel pipe with drilled end caps (think pipe bomb), With an Air hose nipple on one side and a fuel hose on the other side.

Unscrew a pipe cap, fill it full of injector cleaner, screw it back on... pressurize the pipe, use a battery to actuate the injector and it should spray.

Figured out that my dumbass didn't have power to the TAC / pedal. Got it to fire with the same issue. Pulled codes, and got everything pertaining to the TPS's. Of course, you can't just buy the TPS as it is riveted in to the DBW TB assembly. I need one of these:

Been looking, and can't find anything......
I would at least need the pinout, so I can measure it.
Then, I pulled the intake. Oh, the humanity!
