My Project. We swapped a 3.4 automatic with a 3.8 5 speed. now everytime i try to start it, there is sprk but the fuel pump does not send any fuel. when we found a fuel primer line we hooked it up to the battery and got the fuel pumping, and the car still wouldnt start. I dont know what to do. Help!

  • Your service soon light it's not lighting up that is connected to your PCM it not telling the injectors what to do! I don't know what you have done but, I know if that service soon light is off it's not going to run!

  • nah we got it to run...pcm never got any ground. check out the other video.

  • Well I can see your problem. You need to rewire the whole car the inside of it. interior wiring is pre obdII u need to get the whole interior wiring from a 96 to 97 M5 Camaro or bird

  • well why should i rewire if i need a new interior wire setup anyway? we did do some rewiring to get it to crank and spark because at first it was dead and wouldnt do anything. someone said taht i may need a new steering column?

  • You might need a new steering colum why do I say? InsaneABOT just did a 3.4 to 3.8 conversion and that was the same problem he had.

    Check out his channel and ask.

  • he did!! i might have to talk to him. i was told it was alot of things. another reason we said this was a problem because we went from auto to manual. that might have to do with it?

see all

  • having the same problem. how did u fix it?

  • Spartan I believe that's a fuel pump problem. Once it gets below a certain point its not getting full contact with the gas so its not sending it

  • Ecm my fiero 3800sc swap did that.

  • my 94 z28 is really weird, if it gets below a quart of a tank(gasoline), it has a hard time starting, then when i fill it up it starts right up

  • how hard was it to swith the auto to the 5 spd? what all did you have to do?

  • i have a 3.8 wrecked camaro that i want to take the engine out of and put it in my 3.4 could you please tell me what i need to change from the 3.8 to the 3.4 thanks.

  • hey im in the process of swapping my 3.4 but idk wat motor to get. alot of them come to mind but im not sure wat i want.. i was kinda thinkin of a carb 350.. but im not sure if my stock v6 suspention can support that weight goin down the road as far as handling wise and im lookin for a very cheap motor swap cuz im really short on cash. if you can help please do

  • @AustinBWaters do you thin a 3.8 would match up to the transmition that comes with q 3.4
