i recently replaced the motor in my 95 lumina with a 3100 motor the motor i replaced it with ran great before putting it in the lumina,now it wont start i replaced the fuel pump,fuel filter,checked the fuel pressure and i have spark.the motor will fire up as long as you spray gas into the throttle body.i checked the injectors and they all shoot a stream of fuel but the front middle one is the only that keeps shooting fuel as you are cranking the motor.i have had others look at it for me that knows about cars and no one can help so i need some help with this please

 

Was it a 3.1L before you swapped it?

 

both of my motors were 3.1 and i didnt have to change over anything

 

95 lumia van wont start have spark and fuel seem like to much fuel did comp test ok but the plugs were not wet checked timing chain seems tight this has a dist and no obd i got code 34 if you pull 1 injector off it almost wants to start but dont and if you put both injectors in it just seem to flood out both injectors are dumping in fuel but like i said the plugs arnt wet

 

Make sure you plugged all the wires in correctly and tightly. Seems that there is a short or mix up somewhere.
