I'm assuming you are running a MSD box? What Crackedback said, that box and the coil need to be fed in ign1 (run) and in ign2 (cranking) & actually the OE system needs to be also and that ain't being done the way you have it wired right now (your coil & box are OK) tho you might benefit slightly from going to the MSD coil and there might be a longevity bennie related to MSD box/using OE coil combo (I ain't sure on that). Short version: post what system you have and how you have it wired & if you have that correct then with your VOM see if everything is being fed with the key "on" cuz that is when it is going dead

Alright, it starts then dies when you release the key. turn the key "on" & go under the hood with your VOM see if the ECU and coil are being fed. If not then pull/seperate the bulkhead & check there & either work upstream or downstream in that blue wire ign1 circuit for the open. www.mymopar.com will have the colors for you. EDIT this is the OE 4 terminal "dual" ballast/5 terminal ECU system right now?

You've lost power to the IGN1 circuit (blue wire). Check the firewall disconnect for faulty connections.

Mech pump? if so, hook a 5/16 neoprene hose to the inlet nipple & run it into a nearby can of gas then prime the bowls & see what develops. this'll take the line rearward of the pump and the pickup/sock (all) out of the equation. Sometimes very worn pumps have a hard time pumping when being activated slowly with a slow cranking eng & you'll see the effect of that when a car has sit long enough to evap the bowls but with you priming the bowls that ain't an issue. the pump might be totally shot (whats the history on it) and do a good visual on the hard lines and the (2) short neoprene connector pieces (1) up front at pump inlet and (1) at the tank sending unit. I had a '83 Cordoba and the pump outlet nipple pointed to the horizontle line along the frame going rearward (no gas!) took a bit to figure that one out. it used a U shaped piece of hard line to route em right.

You've filled the bowls/inlet hose in a gas can/fired it up? if so does it keep running or die from the bowls going empty?

Pretty much just sounds like the pump is bad. A parts house "airtex" is a pretty cheap pump unless you are needing more capacity than that.

I'd pull the pump & crank it & see if I could see in there to check out the cam eccentric
