of course., they can do what every they please. truely.
some die , only at 3000 rpm.
some will restart by smacking the tank. or the fuel pressure regulator (front of TB )
TB=throttle body.
are you sure car is not simply flooding, Hold down pedal gas, to floor , engaging secret unflood mode (kills all injections when you do that)
on reastart do you smell gas? yes, then it is flooding.
if you suspect flooding pull a spark plug, is it wet or dry. (age old test )
if wet it is flooding,
if not wet then car is starving for fuel
if car is starving for fuel , well give it some fuel, squirt some "
instantstartinaspraycan" into the eval nipple. 3seconds.
does car now crank briskly and start and go Verrroooooooo, and stop.?
yes, then the ECU is ok (mostl), the Injector is dead. (or low fuel pressure)
if you have:
good compression.
good spark
and it runs on test fuel then you have fueling problems.
but.... this can be caused by many a thing.
as always, the first thing on anycar is to see if the ECU , is alive and living in Kansas.
keyON, no start, CEL glowing brightly ( (says ECU just passed its diagnositics)
next insert diag, jumper (paper clip) and see that it blicks out code 12. or ?
next test:
pop tank filler tank cap off, put ear to tank , have Mikey , turn key on.
the fuel pump runs for 3 seconds, no more. at key on. (only turns on 3sec, each key one,no more)
so you need a helper or the TRUNK Monkey (LOL) { dont leave home with out him}

here the buzz? (well its running, wires,ecu,ecu fp relay good , ground good) {but could be weak}
so far so good,
no buzz, then bad Fuel pump or its Enabling circuits.
at this point you can go 2 paths.
1: do the Check Injection signals with a NoID lamp (if test fuel runs ok)
followed by pump tests (pressure) if NOID lamp is good and flashing.
2: if car will not run on test fuel or the car is flooding you have a completely diff. problem and that can be many things. (complex)
Flooding can happen with the following ( how says EFI is simple?)
1: loss of spark . on or all 4
2: dead cylinder (compression test)
3: stuck open intake valve, destroying proper induction vacuum,.
4: timing belt slipped, see #3
5: IAC-E stuck closed (staving engine of lots of fresh air for starting)
6: IAC-T thermo(base of TB ) clogged with gunk.
7: throttle valve (butterfly valve in TB , same as 6 and for same reasons.
someone spun the dizzy. ( old schooler's love to spin a dizzy every time a car stops)
i'd did not mention a tune up. yours is complete. ( all wires,plugs,cap rotor and fuel filter and air filter?)
this data should get you on the correct TRACK.
cheers.
