Cant start 94 cadillac elderado

Radiator cooling fans not working? The ECM is protecting the engine by shutting it down.

wana GUE$$ or test.
which is it?
which engine?, we cant guess them here. ever.
it like 1million post now www, new pump, new (list of 10 things) and still runs bad. why do that>? the tool is 20 bucks to prove pump good. (and a ton of wasted labor)
learn to DIAGNOSE. (?)

i cant help you all, i have only above is parts lists.
we need SYMPTOMS and tests.
all i have is "Stalls while driving."
I assume nothing, I let testing facts dictate all my actions.

ok (50 to 100 causes) so..... what.?
now my 20 questions,sorry , engines and EFI are complex.
hint join toyotanation? not here?

1. starts ok hot and cold engine?.
2. idle at 800 rpm and regulates there hot.?
3. stalls hot and engine,?
4. stalls coming to stop signs? or foot pedal hard, or?
5. does dash lights/gauges go odd just before stall) 12vdc power.?
6. ever get a full tuneup in last 8 years, what is miles on engine.
7. does restart easy.?
8. does doing a fancy right foot action save stall (y/n (hard or easy yes?)
9. if not restart is there spark now?
10. if no restart, does test fuel work,
11. ever read spark plug tips to see if they are black,green ,soaking in fuel or bone dry? or oil soaked ,
12. and more , im tired,

hot or cold engine , or both.?
the oil pressure will be in direct ratio to engine rpm. slow low, fast high
due to the oil pump connection to engine crankshaft.

stalls.: can be caused by 50 things, or just 4 in physics.
the EGR valve (if you have one, no engine stated)
can stick open and stall any engine, and in fact LOVES to. clean it.
1: list 12vdc to EFI. (spark and fuel brain) dash lights dim?
2: lost compression hot, ? compression tests.
3: lost spark, do spark tests. and timing, checks.
4: bad fueling, too much if floods, and misfires and stalls.
too little fuel, it starves and dies.

the 1 free test, is can you save the stall with a fast right foot.

we do the tests. avoiding those 50 guesses....
each tests are simple and the tools dirt cheap .

Sound like crankshaft sensor

It can be low fuel pressure issue or clogged fuel pump.Or its engine related issues,---------------

YEP BAD FUEL PUMP WILL CAUSE STALLING AT LOW SPEED DRIVING ALSO OVER HEATING ENGINE,STUCK OPEN PCV OR EGR VALVE,FAULTY IDLE AIR SPEED CONTROL VALVE,FAULTY TORQUE CONVERTER CLUTCH SOLENOID.I WOULD HAVE CAR CODE SCAN FIRST BEFORE BUYING A $500.00 FUEL PUMP.

Sounds like fuel starvation to me, especially if the scenario repeats itself! Take out the fuel pump fuse, and put an ammeter (which measures current) in series with the fuel pump circuit, and start the engine ... then watch the current reading. Does it start falling off? If so, the fuel pump is losing pressure, starving the engine for fuel!

upper 02 sensor run on a loop till the engine gets warm then it reads the sensor get you back on the road fast it will work better if the engine is warm when you take out the o2 sensor

Replace fuel filter and check fuel lines for any blockage.

TRY ANOTHER FUEL PUMP AND FUEL FILTHER THESE PUMPS ARE FUNNY ON VOLVOS HAD SAME PROBLEM ON 850 TURBO AND SURE ENOUGG IT WAS THE PUMP
