Skubaskott Posted April 3, 2020 Share Posted April 3, 2020 I have an 82 brat I am swapping to Fuel injection using @GeneralDisorder guide. I have everything in place and wired up. My issues are as follows. I am only getting 6 volts at the coil. And I'm not getting any spark. My fuel pump works. But only shoots fuel when it is hard wired. It won't turn on in test mode. Nor when I crank it I don't think. The ecu blinks at me when my key is in on which is a good thing I think And the engine turns over. I have looked and read, then looked and read, then looked and read again through the guide and my harness and I really believe I have everything hooked up correctly. Minus the neutral switch and cel wire. Any any any help would be Uber appreciated!!! Quote Link to comment Share on other sites More sharing options...
naru2 Posted April 3, 2020 Share Posted April 3, 2020 What voltage at either side of the coil fuse and IGN terminal of ignition switch? What voltage at the coil if you remove all wires from coil negative?(key on) Quote Link to comment Share on other sites More sharing options...
Skubaskott Posted April 3, 2020 Author Share Posted April 3, 2020 Wires removed from coil neg I get zero voltage. Quote Link to comment Share on other sites More sharing options...

naru2 Posted April 3, 2020 Share Posted April 3, 2020 12V on BOTH sides of the fuse? Fuse is 4th from the right on the bottom row and labelled "ignition coil" on my 84. If you have 12v on both sides,then there is no connection between the fuse and the coil. Quote Link to comment Share on other sites More sharing options...
Skubaskott Posted April 3, 2020 Author Share Posted April 3, 2020 Does the brat tach wire run through that fuse? Quote Link to comment Share on other sites More sharing options...

naru2 Posted April 3, 2020 Share Posted April 3, 2020 Yes,both power and signal. Quote Link to comment Share on other sites More sharing options...
Skubaskott Posted April 4, 2020 Author Share Posted April 4, 2020 The only wire I have with the swa 4 hours ago, naru2 said: Yes,both power and signal. The only wire I have with the swap that could run through the brat fuse box and the harness is the tach wire. Quote Link to comment Share on other sites More sharing options...
el_freddo Posted April 4, 2020 Share Posted April 4, 2020 So your conversion uses the coil wiring from the brat or the donor loom? Is the fuel pump powered through the beat loom or the donor loom? It should be powered by the ECU which takes its triggers from the optical dizzy from the donor vehicle. If this is kaput, you need another dizzy. I have no idea how to check these things Cheers Bennie Quote Link to comment Share on other sites More sharing options...
Skubaskott Posted April 4, 2020 Author Share Posted April 4, 2020 The conversion uses the donor harness. Donor disty. Donor coil. Donor ecu. Donor fuel pump. Everything from the donor car is powered through the donor car ecu. 1 Quote Link to comment Share on other sites More sharing options...
Skubaskott Posted April 4, 2020 Author Share Posted April 4, 2020 I have figured out if I give power from the battery straight to the coil. Everything works. Though the fuel pump im thinking is shooting to much fuel like it's not shutting off at all. The brat will start and idle for about 2 seconds before dieing unless I give it Gas.
