What gave you the reason to change all the things you have replaced. and just remember just because you replaced something doesnt mean that the part may not be defective... check for fuel, fuel pressure, spark, compression first. then i can help you.

94 ford ranger splash 4.0 will start but dies,i don't know if it is fuel related or what. iv'e changed about everything I know.


Try the ignition module or the ignition switch itself. I have seen them before where they will only get spark in the crank mode. Also check and make sure that your wires are on the correct side of the starter solenoid and not only getting power when you are cranking.

Why does my cherokee turn off while driving.Then i restart it and it runs.ALSO the motor shakes and loses power and turns off.


I would test coil and ignition module. Module has a low speed and a high speed section, so high speed part could be bad and cause unit to die, then start right back up on low speed part.

While driving, the engine dies.


I had the same thing happen on a 91 Olds 88. Replaced crank shaft position sensor, coil, and ignition module. That solved the problem. I think the culprit was the CSP Sensor, but changed all three so can't say for sure.

Cranks but wont turn over


you know. i took it to a mechanic and actually.... The timing belt cut the Crank Shaft Censor... So it was the crank shaft censor again. The wires were routed wrong from the first mechanic that "fixed" the car.

Check and see if you have spark when it won't start. If it don't check the ignition module, Coil Packs,Crank and Cam Sensors. See if that gets in the right direction and let me know if not get back we will see if there is some more things we can look at. Ok thanks Bear001
