i once was rear ended with fast sally mustang (texting sure)
huge plastic front end, on this car, 50mph hit
me, not so good
her car looked ok, the plastic bs popped back looking ok!
but if you pop the hood, it was wreck inside. as expected.
so lightly has degrees, as does all damage.

a short or a fuse

It appears that you have a dead short in the switch, ehich would be like touchin teo wires together. Repkce of switch should solve problem,

fuel pump

check fuel pump fuse and relay also the fuel injection fuse and ecu fuse, if they are ok remove the back seat and you will see a cover remove the cover and check for voltage at the pump plug and ground, you hear the pump work if not need new pump

put the fuse back in pull the positive battery cable off for 30 secs then put it back on. Try restart

Check the immobilizer system, sometimes the fault is in the engine ECM

I had a similar problem, when i would press the gas pedal down X%, the car would shake, and kinda do a "Pop pop pop pop pop" noise.. (NOT a backfire, like a light popping noise), ended up being a tiny air leak in a hose.. Fixed that.. 6 mo. later, a gasket in the throttle body had sprung a leak (Leak of air pressure), and the car is doing this again.. feels like its gonna stall, and does it when i accelerate fast, or go over 60.. This is all because jaguar uses digital gas pedals (VS "Drive by wire"). if this is it, its a easy, cheap fix.
Just start the car, and put your ear towards the engine (With the hood up.. watching out for moving parts), listen for a hissing noise.. Your car should not hiss at all.

It may be the neutral safety switch. Turn the key while moving the clutch in and out...see if anything pops.. Check for a fuse on the safety switch...should have something noted in the owners' manual.. The n.safety switch is the place to start.
