95 Larado 4.0 starting problems?

[sfletcher]

There is no spark coming from the ignition coil. I have replaced coil, there is still no spark. I wire tested the plug going into the coil, it has power for a second when you turn the ignition on but looses power when you crank to get it started. If you have any suggestions please let me know. Thanks

I'd suspect the crankshaft position sensor:

Thank you for posting. I went and purchased the part you suggested and it worked. Thanks again.
