4.0 1999, same as my Cherokee had. (all 3 , i had....)
first off post the symptoms, ive no idea that.?
my wild guess. is:
1: cranks ok about 250RPM?
2: will not start.?
3: i find spark is dead on all 6 cylinders (All six? really?) do tell.
sure it floods, (sometimes, or ecu sees spark dead, and cuts fuel)

4: I connect scan tool, ($9 tool, or rent borrow) i then do these tests
A: i key on , and crank,for 5seconds min, and 15sec max 5 is perfect
B: i look at RPM in scan screen. its good it shows 255rpm'
C: i then look to see if live or pending DTC errors show up
D: i see CMP or CKP errors, BINGO !

that is how to do this. this is first for all no spark on all cars made
1988 to now. (only change is tool used)

the ECU is very accurate, i reporting bad CKP and CMP sensors
LET IT.

why not diagnose it and not GUE$$
why not say, if heat fan works, does it????? that is first ?
and if engine reaches and holds at 180F temp or more. does it?
it only takes 2 things to get heat.

1: hot water 180F passing through the core, (easy tests ,ask)
2: air actually flowing through the core.
just 2 things, and easy tests. ask.
getting hot air to where you want it, that is a whole other matter (dampers)

the answer is here. (basics)

washer pump dead.
never checked for 12v at pump turned on? (2 man)???????
if 12v there, the fuses are and all is working, easy 5min test.
i can see you didnt test the pump, for power.
pump tests (try with no hydraulic load first)
you removed the pump clean it , connect only the wires,
turn it on , does it spin? buzzzzzzzzz, (simple , no ?) it buzzes.

put it back and no hose connected. does it pump water>?
at its output port (open to the world) no hydraulic load)?/?
yes, then it's good. easy huh? and new pump now, so is.... and was....
conclusion here is the head, or load, is packed up.
not free flowing. # 1 cause, of all bad washers. is this...
for mixing wrong cleaners or other bad things in the tank.
solution:
then clean the hoses and nozzles, and some have an inline
check valve, that clogs.

packed or pinched lines
packed check valves.
packed nozzels

get your codes first. as three things in your transmission can go wrong.the pressure sensor.the governor pressure sensor is failing.and your filter in the box very dirty and needing changed .so get the codes first cheaper.

Assuming that you have the proper amount of coolent added, check where your heater hoses connect to the engine block for rust and corrossion, this is a common area to clog up, preventing coolent flow from circulating through your heater core. If ok, check for a thermostat that is stuck open.

i have seen the power distribution box connectors for the fuel pump relay and fuse on the underside of box get hot and short out. need to remove box and check. If no signs of melted connector. you will need to locate the short. It will be a short to ground. on the power side. also you will need to check to see how many amps your fuel pump is pulling when pump is running.

You may want to check the two water houses that feed the heater core. they both have to be hot. (they are usually located next to the thermostat housing.) If they are cold first check the coolant level. Fill up if needed, then you may have to check of there is an obstruction by the housing or the heater core is clogged up. I would first disconnect the hoses and see inside the thermostat housing with a lamp. Also blow some Air inside the heater core to see if flushing is needed. Well if those hoses are both hot then that must be a problem inside the cabin with the vents selection. Either an electric switch or cable. But there are already a few things to check first.

It could be a gudgion pin on the piston that is loose and touching the cylinder wall. It could also be the beginning of a piston and bearing failure. If it is a diesel engine check the injector.
