    camshaft and crankshaft sensors relay info to the ECM, and it uses both to calculate when the coil should fire.

    Sensors usually cause a CEL condition.

    Do you have one?

    Have you hooked up to OBD to check for codes??

Crank position sensor has a higher failure rate than it should...however i would not change it "at random" Check for continuity between b&c terminals of the sensor with a digital ohmeter.
There should be no continuity between them (b&c should be marked on connector) No continuity reading is same as when probes are not connected to each other.
I really dislike when people try and help and use terms that owners can't understand ... "check your zxy and qtr then add an abc" dosen't seem helpful. I hope I am as clear as I can be!!!
Good luck.

    Your original post clearly says that you changed the cps, and coil, then asks if anyone thinks it might be the crank position sensor...
    That would lead me to believe that you changed the CAM POSITION SENSOR (CPS) otherwise after changing it why would you ask if the crank sensor might be the problem??? OK...refrain from buying and plugging in random stuff till it's fixed. Instead, get a decent volt/ohm meter and a manual (haynes, chilton etc). Use the manual and do some testing. Unless you can tow it to a large local auto parts store (many run code checks for free), You will need to individually test all components. At the moment, My thoughts go towards a faulty auto shutdown relay, but without any testing to verify, it's just a guess!!! Testing is exactly what any shop technician would do if he was working on your vehicle...There aren't any shortcuts!!

1994 jeep wrangler no power to coil.....will crank....wont start....changed cps....still does not start....flywheel problem? help...thanx


Is the check engine light lighting up on the dashboard, when you turn the ignition key to on? If not then your ecu is in need of repair since it is not sending power to the coil and probably also not to the injectors also.

'94 jeep engine rotates but will not start


CPS Crankshaft Position Sensor. These are notorious about going bad. It's located at the back of the engine where the transmission meets the block, right side. Good Luck and it's very easy to change out.

1994 jeep wrangler 4.0 idles fine but when traveling cuts in and out and backfires when accelerator is pushed, i do have a cold air intake and jet performance module just recently added


1994 Wrangler with 200,000 miles on the odometer. Similar problem here: Severe bucking and backfiring, and engine misses when traveling down the road. I did an entire tune-up (plugs, wires, distributor, distributor cap, and ignition coil), but got the same thing. I thought it was dirty fuel injectors, so, I poured a bottle in a few times on fill-ups. The final solution, was a bad alternator. My mechanic said it was sending voltage spikes to the computer, causing the engine bucking and back-firing problems.

My 94 jeep wrangler has a 99 engine in it as I take off in all gears it hesitates and back fires. We checked the injecters and changed the plugs and wires and distributer on it. It is still doing the same...


99 Engine is OBD-II.

It must match with the same production line ECU.


You may luck out by getting the chip set for the ECU.


Did you purchase the 99 engine,ECU and the wiring set OFF THE SAME Jeep.

The key is to have a matching ECU firmware to drive the injectors and read ALL sensor.

Go to pick and pull and check out few ECU stock numbers and compare to your

==
There is a "S" for stating it's an auto or stick.

The CPS crank position is differnrt between the two.

This can be your major miss-match.
