Hi. There might be a power issue there. Check your alternator. You must be getting 12 to 15 volts reading.You need to check the fuel pressure at the fuel rail. You can buy a cheap gauge at the auto parts store and check the fuel pressure. It should be about 45-50 psi for a port injected engine and 15-20 psi for a throttle body engine. If not, check to see if the fuel pump, filter or the fuel pressure regulator (FPR) valve are working properly.Change the fuel filter also since you replaced the fuel pump. Next check the FPR. An easy way to test for an FPR leak in the vacuum side is to replace the vacuum line going into the FPR with a length of clear tubing. Now you'll be able to see leak as it happens. IT will most likely show failure when your vacuum is at its lowest point, as in during acceleration.

Intermittent stall accelerating restarts immediately after with no issue no check engine light or codes present.

if this is occurring during acceleration then the components involved may not be the problem
because a motor moves from the reaction to the torque produced on acceleration, I would be looking at the wiring and connections for the position sensors, ECM ,ignition etc
It is known that the wires can break where the motor stresses the wiring, or wiring insulation is destroyed by heat and engine movement then produces a fault that is not always read by the ECM
with the engine idling, try moving the wires and connections to see if you can replicate engine movement and so stop the engine

Why does it run well, then backfire and stall?

make, model, year? backfires are spontaneous burning (exploding) of unburnt fuel outside of the combustion chamber. suspect bad spark plug/s, ignition coils, ignition timing, computer, leaking fuel injector, etc. scan for trouble codes, then post back. because the problem is intermittent, problem manifests only when hot (engine at operating temperature) do tests for both cold & hot conditions. test resistances (ohm) of suspected sensors: cam & crankshaft position sensors, ignition coils (if possible),(search the web for the recommended procedures). also test voltages at the computer (search the web for the pin outs of the computer of your car). also check associated relays (like for the fuel pump, etc.) a bad relay may have its coil open when heated, then becomes good again when cold. i suspect the car may have a good fuel delivery but the sparks are not coming in on demand, thus backfiring.

I have a no starting problem I replaced the wires,plugs,coils,maf,ignition module,fuel filter,injectors,crank sensor,fuel pump relay,altenator,battery,oil pressure switch,Ecm

Are you getting power to the ignition module? It could be your ignition switch. I once had a 1993 Buick that would die intermittently with no rhyme or reason. Turned out to be the ignition switch. And my daughter has a 1995 Camaro that when you would start it...sometimes it would be a 2 cylinder, sometimes a 4 cylinder, and other times a 6. Still not sure how that one worked, but it was the ignition switch that is located on top of the steering column down by the firewall.

Why does my 1995 Lexus ES300 continuously stop when I drive it? I have run out of ideas

When the engine stalls;
Test for spark (ignition)
Test for fuel pressure & check fuel pump volume

Fuel system wiring 1995 sunfire

Could be ECM/PCM but you need to go further and diagnose it. trace fuel pump wires and find out if there is a fusible link or break/bad connection. If you have another ECM you can try it. is there power at the relay? at the fuse? Ignition module?

My 1995 Ranger has been intermittently stalling. Thinking it was a fuel problem, I changed the fuel pump, fuel filter, and this didn't help. I then changed the coolant temperature control valve, and idol...

I would take the vehicle to the dealer or an engine technician who can perform an engine analysis on the vehicle for about $80 or so.

Changing parts may not lead to a solution, in this case.

Intermittent problems like this need to be followed by someone with a scanner for that year.
Unfortunately, the OBD-II system wasn't put on cars and light trucks until 1996 model year.

This 1995 ranger uses an older diagnostic system which the technician will have to be familiar with and have equipment to work on your vehicle.

Good luck on the repair.

1994 ford ranger 2.3litter timming belt broke replaced it know i have no spark and no fuel pump does the crank sensor do that

Yes, if the ignition module doesn't receive the signal from the crank sensor it won't send fire to the coils or the signal to the ecm to run the fuel pump.

1995 cavalier z24,quad 4,dies at random moments.

Have someone else see if their scanner will communicate, if not, this is a sure sign that the ECM has gone bad and will cause intermittent stalling. Normally I would recommend changing the crank sensor for this problem and it still may be the cause if you want to try it first, but it sure sounds like a bad ECM.
