No spark after replacing the CPS

[Kickin’Chicken]

1987 long bed 4x4 6cylinder automatic.
 

I’m at my wits end on this one. I replaced the tank, filter and fuel pump recently. I couldn’t get it to start. Cranks but no start. So I replaced the CPS and still nothing - even when spraying starter fluid into the intake. 
 

Is there a way/wire I can test coming from the ecm?

 

TIA

So it didn't start before replacing the CPS and it still won't start after replacing the CPS?

 

Have you pulled a spark plug to verify that there is in fact no spark?

Using a voltmeter or 12vdc testlight (preferred) check for Battery_Voltage on the following pins (use battery_negative terminal for ground):
D1_5:  Battery_Voltage (Hot at all times)
D1_6:  At KEY ON, (Hot for 2-3 seconds). During CRANK, (Hot at all times).
D2_4:  At KEY ON, (Hot at all times). During CRANK, (Hot at all times).

Absolutely verify you have/ don't have spark before you start throwing ignition parts at the jeep.

I just did these tests and they all checked out.

Cranks but no start before and after replacing CPS.

but have you checked for spark?

pull the coil wire on the distributor (not dizzy) cap and set it close to something metal in the area,  have helper try to start the vehicle, see if the

spark jumps from the coil wire to metal...  (this is easier than pulling a spark plug IMHO).

if you are brave,  hold on to the coil wire  LoL...........  (don't do this)
