Car wont turn over after swap!
Alright so first thing is details. I just swapped a 7mgte into my 7mge supra. I have the same year ecu with harness and motor but my body is 88 which doesnt make a difference since pre 89 are the same. The harness was for a automatic and decided to use a R154 tranny. So I researched how to bypass the nuetral system and spliced the two wires off of one round plug together.
Things I havent done yet is put the Turbo tachometer in yet and thats the only thing. I used the original NA starter and figured I didnt need to change that out. I also got a 100 amp fuse for the alternator, is that the right one or is it a 80 amp? originally there was just a wire connecting to each side to get power to the alternator. There is two small plugs from the harness next to the ecu that dont have a place to pug into, one is black and the other is yellow. And I havent conneted 3 wires that go to the water neck, they are the ones that slide onto the metal like the fan shroud and coolant temp switch. Other then that everything is connected. There is power because I replaced the battery the other day. Any and all sugestions are welcome to what the problem might be? Last edited by Conga1991; 09-13-2010 at 07:04 PM. |

When I turn the key to turn it over theres one click noise coming from where the ecu is, which was kind of strange and I couldnt pin point where exactly where it was coming from.
Also the fuel is going cuz I hear a spray and I have a little fuel leak which Ill fix as well as a small coolant leak on my floor. |

you might want to unplug the fuel injection until the starter atleast starts kicking, so you don't flood the cylinders. Take a vantage or something to the starter wires and make sure you're getting power, you can do an amp test by cranking the started while having the leads in the proper position on the started case and on the big ass wire bolt attached to it, i think thats right atleast its been awhile.

Fix your fuel leak before going any farther.. safety first. Pull the little wire from your starter and have someone turn the key and check for voltage. Again while wire is unhooked from starter. Don't pull the efi fuse or u will lose power to your ecu the main brain of the efi system and that's why its powered from the efi circuit. Check your connections on battery and make sure your ground is hooked to the block below intake manifold. Let us know

you have 2 fuse box, my EFI fuse is located under the hood on the drivers side, its a 15a and is labeled "EFI" check the one under your hood, if not there, check the one in your car by the drivers kick panel once you find it pull it out, if its good keep it, if not go get a new one.. then just turn your ignition to see if you get acouple clicks from the starter..nothing? then take a amp to see if your even getting power to it... maybe you missed wires.. check the amp level any way, i think you should have 1.5? idk im not sure... tell me if you get it working.. |
