Gas tank vandalism
yes it could damage the fuel injectors just drop the fuel tank and clean it out or replace it with a new fuel tank which is $100-$200 at autozone or checker auto.
Chevy truck what causes gas to get in oil?
My best guess would be bad injectors. Theyou may not be closing completely and allowing gas to leak into cylinders and down into the oil pan. Does the engine start right away or do you have to turn it over awhile before it starts? If so probably injector problem.
Hope this helps

Fuse for brake lights keeps burning out
If at this time you haven't really damaged your truck, do this. It doesn't matter which way you go, you must check your wire for a bad SHORT. Your brake light wire is pinched,or rubbing on metal. Remove the wire, don't use 30 amp if 20 amp is correct. If you've done any work on your truck that involved wiring, look in that area. GOOD LUCK FRIEND.
Fuel cut off switch location
The Vehicle Control Module (VCM) electronically cuts off fuel to injectors when engine speed exceeds 5500 RPM . You should hear fuel relay click on firewall when key is turned on . Esay way to check fuel pressure without proper gauges is to diconnect fuel supply line at engine and cycle key , Have plenty of rags around fuel line .
How to get tdc
there are over 6 ways.
to attain TDC #1 firing,
on all engines, you never stated what engine is in your car.!
nor what state engine is in, nor how you lost it. (heads off?)
or?
on all V6 and V8, #1 is the most forward cylinder, look carefully see that? that is true on all cars.
then, if the engine is all buttoned up, (is it?) you cant watch the valve actions, making it impossible to see them.
so... i pretend that is your case, worst case.
there are 2 ways, in THIS case.
the blow test, or the compression test.
1: some put tissue paper in #1 spark hole
then rotate crank pulley by hand until it blows out. this is the compression strock , the begining then keep moving until the
crank pulley zero degree mark aligns with the pointer.
you are at TDC #1 firing now.
2: same deal but use a compression gauge.
when the gauge begins to rise. bingo, its on the beginning of the compression stroke, moving up. stop at zero.
done.
there are vastly more easy ways with valve #1 clover off.
