Car stalled out one day . I changed the battery and fuel pump and it still doesn't start. Cranks but won't turn over? Can anyone pls help me

You basically had a intermittent problem,If anything it probably was not the fuel pump, In order for the fuel pump to turn on the ECM, needs to see a crank value, of 250 RPM or the fuel pump will not turn on, what gives this it is the crank sensor,The crank sensor does age and when it goes out you can be driving down the freeway and all of a sudden the car stalls,and it doesnt start up,

Mine just had these same symptoms, and it was because the fuel pump had died, and I had to replace it. But first, check the fuse panel to see if maybe there's a dedicated fuse for the fuel pump. If so, it may e as easy and inexpensive as replacing that. I wish you luck! I had no transportation for three weeks before I could get it fixed!

Have you ever heard of testing before replacing parts ? Fuel pressure an flow tesing , testing the electrical circuit for the fuel pump , amp draw testing , voltage drop testing etc... Thier are no magical fixes in auto repair . No spark ! check B+ voltage an ground circuits for the ignition system , Ignition System Designs Operation and Testing an SD Premium video

sorry turns over means ZERO
the crank shaft can spin or not
the starter can in fact spin and crankshaft not.
and some think turns over means, engine runs. now that fact makes turns over, a dead statement.

the word is cranks over, the engine cranks over robustlyl
and then the engine runs.
then runs for more that 3 seconds, and the ASD relay holds. (step by step his works like this ,93 to now)

wont crank ? (clear statement in fact)
cranks ok, (crank shaft spins fast) can be seen and heard.
runs for 3 seconds? and stalls (ASD relay drop out) can be seen.
runs for 5min and stalls. (complex)
runs for hours and stalls. (even more complex)
all are key facts to the solution.

tell more..... tell all it does good bad or ugly
for better suggestions!

Have you checked Google I found this hopefully it's not your timing or it may be flooded but doubtful have you tried spraying starting fluid into the intake while cranking it

It sure could be. But, first...by "won't turn over" you do mean it cranks at normal speed but won't start?
A simple test of the fuel pump is to stand by tank and listen as someone turns key to on. When first turned to on, your pump will activate for 2 or 3 seconds, pressurizing the fuel system, and then shut off if the engine computer doesn't get a cranking signal. Do you hear it come on? If not, then something's not turning your pump on. If you can hear it buzz on briefly, then maybe it's your filter. Another test: Spray a little starting fluid into your intake manifold (remove the big hose going into intake manifold) while someone tries starting it.If it doesn't fire and try to stay running, then it's probably an ignition problem. But if it does fire off, then you know it's a fuel problem-likely your pump or filter. good luck.

yeah, try starter fluid just to verify if it;s fuel or spark related. If it starts or tries to, then it's a fuel problem. You should be able to hear your pump turn on, when you turn key on, may need to stand by tank, when someone turns key on. it should activate for about 2 seconds, with key on.(that's to pressurize your system with gas) then when cranking, the pump should run(may not hear it then-so just listen when key is initially turned on. No noise: your pump may not be working. If you can hear the pump, it may be another issue.

your terminology is wrong.if it cranks its turning over what you mean is it won`t start(fire up) as you said at the beginning.anyways it sounds like you could have a fuel pump problem that stop working.this happens alot.you should check for spark at the plugs to make sure its not an ignition problem.did you notice a check engine light on when it was running.if so there will be a code in the ecm and may be the cause of your problem.

sounds like a fuel pump or filter problem. replace filter first its cheaper than a fuel pump.my fuel filter on my 01 530 was under the driver side half way back along the bottom rail of the car.i had to remove the aero plastic with a plug puller that gave me acess to it.try and replace that first. if it doesn work its prob.fuel pump.

check to see if the fuel pump is working. it should turn on for a couple of seconds when you turn the ignition switch to run.
