Purchased new well pump have electric however the pump will not start

new lift pump ? Fuel pump . Do you know what a wiring diagram is ? How to voltage drop test fuel pump electrical circuit ? https://www.youtube.com/watch?v=IuP0ZEHfDJ4

See if the motor is running. You should be able to hear it. If it is then you need to check the prime. If it is a prime issue then the motor runs the risk of never shutting off and could overheat.

What make , model and year vehicle ? It makes a difference . It does start but stops running right away ? Before replacing the pump and regulator did you do a fuel pressure test ? Hooking up a fuel pressure gauge ? Or just guessing that was the problem ? And did your test the electrical circuit of the fuel pump ?

sounds like a faulty pressure regulator be sure to test it before changing it

Your motor is covered under a 1 year manufacturers warranty. The issue you describe can be one of a couple problems all of which will lead to permanent motor failure if not corrected. I'd suggest you go back to the place of purchase or contact AOSmith for a warranty center near you.

That is the classic symptom of an electronic component overheating, and it could be a problem with the fuel pump, the ignition module inside of the distributor could be faulty, or the ECM (Engine Control Module) could be faulty, and the ECM's that were manufactured back then were prone to faults, and that is also why they can be purchased for only around $70.00 at most auto part stores.

The ignition module located inside of the distributor is what generates the signal that the ECM (Engine Control Module) uses to time and fire the fuel injectors, as well as the signal to run the fuel pump and the dwell signal timing to fire the ignition coil. A faulty ignition module can cause any one of these systems to malfunction.

That does sound like a malfunction with the ignition module inside of the distributor, and you can remove the ignition module and have it tested for free at most auto part stores.

If you do purchase a new ignition module be sure that it does come with a silicone grease or a die-electric compound because it is a heat sink and the ignition module will burn up without it.

To install the new ignition module first clean out the mounting surface inside of the distributor. Then completely coat the metal contact surface under the ignition module with a thick coat the silicone grease or die-electric compound and do not leave any of the metal contact surface of the ignition module un-coated with the silicone grease or die-electric compound, and be very careful not to over-tighten the ignition module or it will be damaged.

Replace the oil sending unit,it has a safety feature of cutting off the fuel when the pressure from the oil pump is low,and the sending unit might be the problem.

check for a re-set button somewhere on the motor housing.

You problem could be one of several things. First, pumps have a thermal protection switch that shuts the pump down when overheated. You could have rust after only one season that overheats the pump and it shuts down. The switch could be bad. There could be an electrical issue when running it on a long cord of the wrong gauge. Plug the pump into an outlet without extension cord and see if it makes a difference.

you may have water in the line.
purge it at pressure regulator on fuel rail
