i used starting fluid and it fire up for a couple seconds...without it it just cranks and cranks, but its open header and I dont wanna burn a valve so we stopped trying...truck has a 4cyl exhaust but a 3vz swap so it doesn't bolt to the headers.But i replaced the pump, tank, and filter...I think the lines may be clogged the pump comes on but it seems like its still not getting anything to the rails...im gonna start back at the pump and make sure its squirting out. I have a feeling it could possibly be wiring also they appearantly tried o make their own injector harness when they did the swap
