Has fuel pressure, has inj. puls, has spark, no codes, cranks fine, 125 psi compression per cylinders no start
Did you fix this yet, old post.
which engine, we cant guess that. ever.? (we know it's not a diesel)
if the engine has spark and fuel
and it dont start:
it's flooding? (spark tips soaked in raw fuel, ) we look at them......
did you try the operators guide trick, cranking with wide open throttle?
this cuts fueling , clearing a flood condition.
spec, is 120 to 150 PSI. 4.0L
or 4.7L?
good spark to ALL cylinders is the correct test, not just 1.
does the timing light show correct timing? cranking? spark timing?
ever do a tuneup, with new spark plugs yet.
If the above is true it will start. or at least on test fuel.
one way to find problems like this , if the spark is good.
is to cut all fuel injections. (i kill the fuel pump, ask how.)
and start car with test fuel, if it runs for 3 seconds each try.
then all is good , engine and spark, if not , not.
a simple test. that is. and works on all gas engines.
watch scotty.

in this case he assumes the engine is good. and timed right.

I can run any engine, with no fuel in car. sure can.
and is safe to do.
use CRC.

SOURCE: JEEP WAS RUNNING FINE SHUT IT OFF AND WENT TO
pretty sure the injectors run of the ecu but woudnt swear to it cant u loosen a fuel line and see if pump is working
SOURCE: 1999 Jeep Grand Cherokee Larado wont start.
If computer sees no crank sensor signal it shuts down pulses to the injectors. But, you bring something new into the mix. Make sure fender grounding is good so the relay can operate properly and make sure power going to it is not restricted by a loose or dirty contact on the power side.
