I would check the coil to see if the power side is getting battery voltage with the key in the on position. It could be the key switch.

SOURCE: cannot find the fuel pump fuse on 95 toyota tercel

Get a tester light and check all the fuses with the key on. If not I think it is the efi fuse. The fuel pump has a relay too. Pump is in the tank .

If the fuel pump operates with with a jumper at data link.That clears that the fuel pump is running.So check the EFI relay and the fuel pump relay. Now what is EFI relay:--- EFI Main Relay The EFI fuse supplies constant battery voltage to EFI main relay. The EFI main relay provides battery voltage to +B terminal of circuit opening relay (some models) and data link connector. Depending on model, EFI main relay may either be turned on directly by ignition switch or by M-REL terminal of Engine Control Module (ECM). The EFI main relay may also provide battery voltage to +B and +B1 terminals of ECM when ignition is turned on. The EFI main relay is located in engine compartment relay box. NOTE: Circuit opening relay is used on all models. Circuit Opening Relay Circuit opening relay controls fuel pump circuit. The Engine Control Module (ECM) receives an input signal at STA terminal when engine is cranking. Starter signal is also applied to STA terminal of circuit opening relay. Starter signal energizes circuit opening relay during cranking. Circuit opening relay then provides voltage to fuel pump or fuel pump relay.The circuit opening relay is grounded by ECM through FC terminal.Fuel Pump Relay & Fuel Pump Resistor .Fuel pump relay receives voltage from circuit opening relay and operates fuel pump. Fuel pump operating speed may be varied by Engine Control Module (ECM). When ECM grounds fuel pump relay, relay contacts close, and voltage is supplied through fuel pump resistor, to fuel pump. This changes fuel pump operating speed. ---------------------- As there are many other possibilities to check out of the mentioned procedure.But as you said fuel pump works with jumper wire and the fuel pump relay is replaced,on as per that i think the problem is the Fuel pump relay connections.The relay ground wire is connected to the ECM.If this wire is not connected properly or if this ground wire is got short or in-case not connected,then the ECM will not send signal to fuel pump relay to get started so it will not let the fuel pump start.But in jumper wire connection the relay is bypassed so no ground connection required and due to that fuel pump works. Thanks. Keep updated for any more query. You can rate this solution and show your appreciation

Sounds like it may be the fuel pump relay, when it gets hot it doesn't want to work properly. However; I would also check for a vacuum leak around the intake manifold. I would also check the throttle body seal between the intake manifold and the throttle bod itself, this can cause the exact condition you've decribe. Hope this helps you get started looking in the right direction.

Engine seems to stall when first starting in cold weather after its warm it runns great

Will it stay running if you keep your foot on the gas? If yes it sounds like you might have a bad Idle air control motor.

I git an 87 plym reliant and it will start but will not stay runn

I would suspect the pickup in the distributor. It is a common problem, and a fairly cheap and easy try. It is located under the rotor button, and should be about $15-20.

Engine turns over but doesn't start

Did you replace the spark plugs? Did you do a tune up?
The gas may have condensation water if you didn't keep the tank full in cold weather. Try this and possibly add a cleaning agent for the clogged lines.
