No start
We have a 1994 Grand Cherokee, did a motor swap in it and now we have no fuel getting into the rail.
New
Fuel pump
Fuel filter
Fuel lines
Fuel pressure Regulator.
We have fuel up to the fuel pressure Regulator but nothing past it. If I put gas in the intake tube it will fire up and run. I' m at a loss now and don' know what to look at next. All the fuses are good.
FYI it was a running rig before we did the swap has 230k miles on that motor and the one we put in has 40k miles. Donor was a 98, swappe the manifolds and everything electrical. New plugs and wires new coil. Just no gas past the regulator.
thank you for any help In advance.

You already checked that you didn't pipe the regulator backwards? It is an easy mistake to make on certain engines.
