Check the fuses. If they are in good shape then the problem is the wires to the pump

you failed to say, does crank, when it don't start?
and btw, the fuel pump on most cars only run cranking or running
some run for 3 seconds, key on, but you'd miss that fact. using
only one person.
the key word here is crank, does it crank as full speed, via the cranking starter motor. that is the engine cranks spins fast.
on this car it will spin min 250 RPM, cranking, and uses large
battery current , so on diesels it takes a very strong battery to start
and working glow plugs.

That is a false statement

You can put an Ampere Meter on it, when it is running

You can look at the motor running with an Oscilloscope

You can check Fuel Pressure & Fuel Volume

Your problem has nothing to do with cranking
Cranking is the starter turning over the motor

You have a no start condition, due to lack of fuel pressure

Now you see why I never recommend a dealer
Why would a professional tell you that stuff?

You have a complete fuel pump circuit with other items
that can be checked

You could install a new pump & hope that is the problem,
but if it took 6 months to come back I doubt it

Bad fuel pump, clogged filter or bad fuel pressure regulator. If you put starting fluid in the intake, does it start up? Your fuel pump should start running as soon as you turn the key to "on" You only had to crank over older engines to pump the fuel. They used to use crankshaft driven fuel pumps back in the day, but now they are all electric. Since they are electric, it should have a fuse, and a relay associated with it. Check fuse and see if relay pulls in when key is switched to 'on'.

2000 jimmy will crank but wont start, fuel put is


Then it is the fuel pump. Can you hear the fuel pump come on if not that is what it is. That is why when you put fuel in the intake it started. Good Luck.

Does fuel pump have a reset


Can you hear the pump run when you turn the key on? Remember that system is pressurized and will easily spill because of this. There is no reset for fuel pumps, that's on Fords. If you pour gas into the intake it starts, then I would tell you to take a long handled screwdriver or a stetoscope if you have one and place it on one of the fuel injectors and listen when someone cranks the engine. If you don't hear the clicking of the injector while cranking, then your problem is not fuel related. Maybe crank sensor, or even computer. The computer not the module is what controls the fuel injection. The module controls spartk just to let you know. Try getting a trouble code...Hopefully this gets you in the right direction. Good luck.

Trying to jump start but will not start, it took a jump one time


hmm I'll need some more information to be of more help, for example is it tumbling but not starting, is it a powerful tumble>>??

Any way here is how to check the fuel pump,,

1.) locate the gas filter by the engine, there is a hose leading to it and one from it to the engine.

2.) remove the hose leading to it and stick it in a bottle.

3.) turn the ignition on, if the pump is working gas should flow into the bottle.

4.) replace the hose to the filer

5.) remove the hose from the filer to the engine and place that in a bottle.

6.) turn the ignition on and see if gas flows. if it does the filter is fine.

NB.. Check the gas in the bottle for signs of water this will cause a problem.
