no sparking 90 xj

I just did a 4.0 swap on my xj. everything was ready to go. NO SPARK!! i check out the ign. mod. and it is recieving and putting out power but still no coil action. I also disconnected the CPS and cranked it over. the volt meter is showing zeros, although it still looks intack. One thing to mention is that there was a small melt or fray in the wire when i took the engine out. I taped it up. anything left to check or any ideas of what it might be would be awesome.
Also thinking about checking fusable links, who knows. thanks!!!!

Unplug the CPS and do an ohm test, see how near it is to 200 ohms.

I did the ohm test, getting virtually nothing. 4-5 if im lucky, any one know where to get some diagrams or maybe some procedures? thanks!

You should be getting a reading anywhere from 175-275 If memory serves me right.

CPS TESTING PROCEDURE 1991 – 2001 4.0L H.O. engines

1. Near the rear of intake manifold, disconnect sensor pigtail harness connector from main wiring harness.
2. Place an ohmmeter across terminals B and C (A-B-C looking into connector left to right with the part with the notch in the middle on the right) Ohmmeter should be set to 1K-to-1OK scale for this test.
3. The meter reading should be open (infinite resistance). Replace sensor if a low resistance is indicated.

CPS TESTING PROCECURE for 1987 – 1990 4.0 L engines

Test # 1

Get a volt/ohm meter and set it to read 0 - 500 ohms. Unplug the CPS and measure across the CPS connector's A & B leads. Your meter should show a CPS resistance of between 125 - 275 ohms. If the CPS is out of that range by much, replace it.


Test # 2

You'll need a helper for this one. Set the volt/ohm meter to read 0 - 5 AC volts or the closest AC Volts scale your meter has to this range. Measure across the CPS leads for voltage generated as your helper cranks the engine. (The engine can't fire up without the CPS connected but watch for moving parts just the same!) The meter should show .5 - .8 VAC when cranking. (That's between 1/2 and 1 volt AC.) If it's below .5vac, replace it.
