Thread: 3.1 mpfi to dohc 3.4 swap

Update on the build.... She lives!!!! Got her fired earlier... Didn't have to rewire the dash... Just one wire...Tip for anyone upgrading engines to later years... If you do the swap and it will not crank, no dash power, not much of anything... try running a power wire from the battery to the ecm and try firing it like that... if that works then you can do like I'm doing and using that wire as a kill switch... or feed that wire into the ignition power off the column.

thanks for that bit of information.

Just to try it to see if it worked, I ran a wire from the battery to the ecm fuse in the engine compartment. And it worked... Only issue I have now is the fuel line is leaking and when the fuel hit the flames out the header it burst into flames lmao good thing we had a fire extinguisher or bye bye gp -,-
