I've got an '82 J10 with a 258 and homebrew TBI. The Jeep has been parked in storage for the last 2 years and was started and run quite a few times in 2016 and only once in 2017. Went to go pull the truck out of the garage and threw in a new battery. When I turn the key I can hear the fuel pump doing its thing and there is fuel in the lines and fresh fuel in the tank but when I try to start the truck all it does is crank. I manually poured fuel down the throttle body and the Jeep fires right up and runs but does not stay running unless you pour more fuel down the TB.
Not getting any trouble codes and everything I can find online says that this usually only happens if there is no spark, but that's not the case.
I flew cross country thinking I could hop in it and drive off but the Jeep has other ideas...In the past it's always been dead reliable, LOL! It did the same thing last year but after a splash of gas down the TB it fired right up and stayed running.
Anyone have any ideas?
Thanks.

You know it's bad when your car is on the EPA's 10 most wanted list!
If injectors are not firing & you have spark, the ecm is probably not seeing the tach signal?
Since no idea how it's setup...
check obvious, fuses, wiring especially grounds, and they tach signal to ecm wire.

Injectors could possibly be clogged. Gas these days does some nasty stuff when it gets old. I left my TPI motor sit for too long and all but 1 injector was clogged up. Had to send them out to be sonic cleaned.
I'll finish that sentence.....It still wouldn't start
Actually I had REALLY good luck with my Weber but in 2015 the carb was feeling really tired and I thought I'd get all fancy and fuel inject it for Ouray 2016, and I ended up going in the wrangler anyway. Towing the trailer up the passes on I70 the 258 in the J10 dogged pretty good.
