New engine in, getting no spark from ignition coil and I have a check engine light on.
All grounds clean and tightened, I can capture pictures if it helps.
Ide hope a scanner will point me on where to look at least.
Thanks for any help,
Matt

Good progress on the engine swap!
Sorry, I don't have one.
Does the local auto store loan them out or do you need to drive up for them to use theirs?
I keep a $15 scanner in my vehicles. Would recommend borrowing from Autozone or Advanced Auto Parts -type place if you need it now. Would gladly loan to you, but I'm no where near FoCo.

The key trick is for newer models I believe as it's never worked on mine. Unfortunately auto zone and the like a do not loan scanners.
Harbor Freight offers them fairly cheap and usually interface with your cellphone.
Got a bluetooth scanner from a friend. Is there anyone here that can help get their hands dirty on getting my jeep running again, I need someone that knows what they are doing, or anyone that might be a good contact to ask? I'm beyond what I know to do at this point.
Thank you
I'm no OBDII wizard but I'm capable enough. I'd be happy to stop over to see what can be done.
Gett'n spark... Is spark in time... Gett'n gas...
I was wondering if you got the engine from a similar year and don’t need to change the ecu?
Do you hear the fuel pump spin up when the key is initially turned to RUN? Do you have fuel / fuel pressure at the rail?
This is still coil and distributor spark, yes? Is the coil getting 12vDC? Is the coil "giving spark"?
Is the crankshaft position sensor the same between the two motors?
A big question - what code or codes are being thrown?

P0122 throttle position circuit a low. I haven't read anything that says this will prevent starting.
Do you have a multimeter?
This might get things close:

If the reference voltage is not there, it may well be affecting other items which in turn are keeping it from starting.

Got some questions, how did you test for spark? Did you confirm fuel pressure in the rail? How did you set the distributor? Make sure you are at top dead center on intake stroke not exhaust stroke. The engine is cranking?

Im happy to answer them. The engine is cranking. The distributor was indexed using the toothpick trick/ aligning the holes on the spindle and housing. Top dead center is indicated by lining up the harmonic balancer notch, with the notch 0 on the timing cover, which I did. I have not put a fuel pressure gauge on the rail, but the pump primes every time and I bled fuel from the rail just to make sure it was making it there. I tested for spark from the ignition coil out with a test light.
I do have a multi meter Jim, I'll review the article.

So... easy test is to index dist 180deg and hit the key!
