Were is the cam shaft senor and the crank shaft senor located

when you say crank ,,, that means engine does not turn over when you turn the key to start position ,,,, as you said you use start spray this means engine is turning over ,,,,, i think you mean engine turns over but wont start,,,,,,, cam sensor will cause engine to be slower to start but you would be better to get the car plugged in to see what the fault codes are in the system ,,, also if no codes the data list of the engine sensors will show up a faulty sensor ,,, to be honest there is no point in spending your hard earned cash putting in sensors until you carry out a diagnostic check and only have to change the faulty sensor that shows up...best of luck

fuel pump pressure about 35 psi

below center of I/P

If all the fuses are good,replace the crank shaft sensor,this is the problem.

Remave the battery cables from the battery and clean the connections and replace bolts. Have seen this before.

The crank sensor is located on the trans. bell housing.Look behind the engine where the tranny bolts to the block and on top of the bell housing just a little off center you will see the sensor which has 2 bolts mounting it in place.It has a 6in length of wire attached to it with a plug on the end.This sensor reads off the flywheel.Hope this helps.

It is part of the distributor according to a chevy forum I belong to

the cam shaft sensor will belocated in the rear of the engine block it will have a weatherproof 2 or 3 wire connector.

The crank sensor is a well known cause of no spark condition, it is most likely the real problem, the crankshaft sensor for a Jeep 2001 is located behind the starter, you have to remove the starter to gain access, even then it is hard to get at.
