Re: How do u know if a crank sensor is bad on a 1994...
Check to see if you have any rpms on your tachometer in the car during engine crank. If you do sensor is probably fine but if your needle doesn't move at all sensor is bad. Your problem might be the same as mine at the coil pack/module connector. Four wire connector that was not getting a good connection. I got very lucky to have found this.

temp sensors, lambda/oxygen sensor/ reading wrong temp -
they would both increasse fuel consumption - have the diagnostics checked at garage.
Air filter, it it clogged or really dirty?
Tyre pressures - make sure they are upto reccomended pressure,
(extra pressure reduces rolling resistance and increases fuel economy but at the cost of grip...)
The crank position sensor on a 1993-1997 intrepid is located on the passenger side of the transmission bell housing ( top ) breeze to change and usally fixes the cold starting issue with these automobiles ( usally ) for $40 or less it is worth a try!!!!!
Check your Ground connetions from the battery to frame and frame to battery also check your battery to see if the cables are clean and you have no resistance, There should not be more than .2 ohms resistance on any ground. As well check the chargeing output of the altanator. is it less than 13.5 volts or above 14.5 volts? if so then you need to see if the battery has a shorted cell, and test battery voltage. These are all things that you can do yourself for free. then we can go to the next step. You can also go to this web site and get the repair manual online and look this up and see if there is a recall on this problem. One last thing it also could be a crank bearing going out. Did you set the correct air gap on it? Let me know if you need more help and thanks for using Fix-ya, if this helped please rate.
Crank Sensor: Passenger side of transmission just to right and above the differential cover. Has 3 wires:
Light Blue/Dark Blue stripe - Signal
Dark Red - 8v supply
Black/Light Blue stripe - Ground
If the car runs or cranks, you can test this sensor by first checking for power on RED wire with key ON. Should be 8-9.5 volts DC. Furthermore, connect a dwell meter to the
signal wire by probing the back of the connector. Dwell reading should
be 49-51%. If not, its likely bad.
If you remove the sensor, you MUST replace the paper spacer on the end
of the sensor or you risk damaging the sensor or even the torque
converter drive plate otherwise. Also make sure O-ring is in good shape and positioned properly. Cam Sensor: Facing Engine, it is on the driver side timing case housing, on
top of the round part, just to the right of the fuel rail pipe where there is a capped
Has 3 wires:
Tan/Yellow stripe - Signal Dark Red - 8v supply Black/Light Blue stripe - Ground
I had a very similar problem as most did on this stalling out, no start, and no spark on my 1994 Dodge Intrepid 3.3L V6. I was told to watch my Tachometer in the car to see if it moved at all while cranking the engine over. It did not move. So that told me the crankshaft sensor was not picking up any signal what so ever. I changed it. The engine immediately started. So I left the engine run for approx. 25 minutes then the engine died. I had again lost spark but had minor RPM on the tachometer during engine crank. I dug thru all the wiring harnesses and found that when I moved the connector to the Coil pack/Module the engine would start. I got the problem narrowed down to the connector but have not replaced it yet. I put a little slack in the harness the wires run in so the harness is not pulling on the connector. This has seemed to solve the problem for me. At least for now. firstname.lastname@example.org
Check the voltage on your battery with a voltmeter should be at least 12 volts without any power hooked up to it.
Pull a spark plug wire off of the coil, have someone crank the starter and hold the plug wire very close to the coil (same place you pulled the wire from) to see if there is a spark. Be careful and stay away from the engine will it is cranking
Charge the battery.
Check altenator belt and connections.
warm the car or battery (can you get the car in your garage?)
