Location/testing of crank sensor 1995 jeep wrangler

close your eyes. picture a pcm. now picture a ckp(crank sensor) at the bellhousing. now picture a u-tube video about howto test a crank sensor, jeep grand cherokee. now picture a "fluke" test meter or equivalent. or picture a towtruck taking it to the jeep dealer to get your pcm out of sleep mode by a drbIII scantool and run the tests to diagnose

Do not know all the specifics like what engine ect... Most speed sensors are located by transmission valve body area.

Your ecu is in need of repair. Your jeep has what is known as the "delayed check engine light problem". Time has taken it's toll on some of your ecu's internal components, the ones that supply power the fuel and ignition circuit relays. The ecu is slow to supply power to the circuits in the morning, causing the delay. Your jeep may also have a bad crank sensor, which would cause the sudden shutdown while driving. Your ecu can be repaired or replaced, your choice. Both options are available on ebay.

You might want to check your crank sensor

wall5552: there were two engines used in 1992 Jeep Wranglers.
A 2.5 liter and a 4.0 liter. HOWEVER>>>> The location for the crank angle sensor is the same for both.
It is located on the bell housing up near the front at about the 10:00 PM position.
The Cam position sensor is located in the Distributor on both engines as well.

Most common cause is the crank sensor...It tells the computer when to fire off coil. Cam sensor does this as well but is less prone to failure. Don't change parts because I said so! Proper testing is essential! Test b&c terminals of sensor with an ohmeter. There should be no continuity there (same as when the ohmeter probes are not connected to anything) Terminals should be marked on harness connector.

Check the coolant sensor, cam and crank sensor and make sure they are all plugged in.

have the coil tested

if no check engine light is on, check the egr valve, sounds to me that it is stuck open or the egr silinoid is bad
