hot engine or cold, or both? 180F+ is hot.
Shuts off, idling or on the fly, say at 30mph right foot down it dies?
just clue here...
engine stalls. is complex. but in the macro its below, using tools finds the reason,, but you never said did it restart easy./??????
1: lost of engine compression hot engine, (or overheated)
2: lost 12vdc electric power at stall (caused it) dash goes dead. ?
3: lost spark, test spark at the failure point. if dead trouble shoot speak.
4 bad fueling, too lean (say the fuel pump dies) or too rich.
too rich causes wet spark plug tips. (lots of causes )
5: stalls due to idle RPM too low, below 800 is too low.
too low idle rpm is caused by many things, but top 2 are.
A: EGR stuck wide open, clean it, as the books shows at 60k miles
B: ISC stuck closed. (same deal clean it)

now repost and say when it stalled,
at a read light or flying up a hill wot, wot= wide open throttle.
and when it dies, is the restart easy or hard.

wont crank or cranks fast but will not start,????????
wow first thing replaced the most expensive part on car.? why ?
replace PCM. ! wow ! what if used PCM (is it used) is bad,?
if so now 2 problems, Compounding every thing,.....$$$$$$$$

last time it ran was 1 week ago , 1 year, what? miles on it?
bad fuel in tank , old?
why not elaborate that key symptom first.?
there is a cluster there.
gauges, warning lights. many, all must glow.
lets do this dance, posted 100 times;. now.
  1. head lights work not dim? key in pocket.
  2. key on, not cranked ! (covered in missing oper. guide)
  3. all warning lights glow, if not battery is weak or fuses blown.
  4. and the CEL lamp there, it must glow or the PCM has no power ,that too, is a blown PCM fuse. fact. (or lamp dead)
  5. lets say the lamp was dead,CEL the scan tools hows status of the lamp and all else, so use a $10 scan too now. does it communicate with the PCM and show all sensors and not DTC errors? scan it now, cant fix cars now , with no scan tool , buy one, and win on old cars. big time with pay back !!! heck all cars. 96+
  6. so the CEL glows now, good, now you crank, now, does the crank shaft turn fast cranking, yes/no. yes !
  7. then check for spark , got spark x 6?
  8. got spark well test fuel works now , even with dry gas tank.
  9. is the ASD relay closing and then dropping,? ( yes, and yes)
  10. then that means the PCM cut fuel , on purpose !!!!
  11. the scan tool tells you why. it did drop for sure. scan it.

1993 to now , MR. ASD 101


PCM is the engine EFI brain, it runs all spark and all fuel all the time. it also dumps the ASD to stop engine fires, by law.
confuses many, and all cars have this, one way or the other,
all EFI cars.

you might have a bad wire harness from sensor to the computer. check the wires you might have a burned one or it is cracked. clear codes and try again.

There should be NO brake lines that are plastic. What the plastic line may be for is fuel, fuel return or the Evap system.
And I have seen where those lines will devolpe a leak from a pin hole, crack, split, O-rings in the ends.

A manual transmission could also have a plastic line from the clutch master to the clutch slave. So if you have a manual and it was brake fluid you saw leaking from it that could be it as the Hydraulic clutches use brake fluid in the system.

Check the Fuel Pressure, you may have a bad fuel pump.

well it sounds like some steering components are worn, look under the car and watch as someone turns steering wheel, be careful. if you are not experienced enough to do this safely take it to a good shop, expect to spend between $200 and $1000 ( or more) for repairs. A good shop should check it out and prepare an estimate for free, a really good shop will tell you what to fix now and what to fix later

Check your battery if everything else seems fine. Otherwise, I would need more information about what the car is doing when you try to start it.
