revhead 1,392 Posted May 12, 2020 Hey guys. I've done the engine n gearbox swap from eb back to ea using 1988 EA engine harness, I've changed it from auto to manual. Using factory manual harness,I don't have spark or a signal from ignition to starter.Fuel pump is working, it's a 4.0 into a 88 ea, it should plug in an runI've fitted new dizzy n coil. New leadsNow being a mechanic, I'm over looking something.This car DOES NOT HAVE SMART LOCK.

deankxf 20,292 Posted May 12, 2020 i've seen quite a few instances of the ignition switch failing in these 25yr old cars, any chance it's just failed now? @SPArKy_Dave @Thomare good with the wiring of these, might have a fusible link issue for eg, 3 CHESTNUTXE, gerg and revhead reacted to this Share this post Link to post Share on other sites
gerg 10,871 Posted May 12, 2020 I had an EA but never messed with the wiring. You say that the fuel pump is priming key "on", is there another relay for ignition as well? Are you getting injector signal? Is your computer earthed?Sent from my CPH1903 using Tapatalk 1 CHESTNUTXE reacted to this Share this post Link to post Share on other sites

CHESTNUTXE 7,312 Posted May 12, 2020 thom will chime in soon with an answer ,but what about the computer maybe the 88 only works with auto,did you swap them. Share this post Link to post Share on other sites
wok 206 Posted May 12, 2020 just a thought but did you bridge/join the inhibitor switch wires ? this used to be a trap when doing auto to manual on the older falcons, not sure if computer controlled or what in the EA....and maybe you wouldnt hear the relays go if they weren't joined ...i'm not sure on these "modern" cars.... 1 gerg reacted to this Share this post Link to post Share on other sites

SPArKy_Dave 8,881 Posted May 13, 2020 If the dizzy isn't getting power, then the ECU won't fire the injectors. I'd be checking some powers and grounds in the engine bay personally. You may have accidently blown a main fuse? 2 revhead and CHESTNUTXE reacted to this Share this post Link to post Share on other sites

It will support a low load - ie test light, but not high current - ie, starter solenoid. 1 revhead reacted to this Share this post Link to post Share on other sites

gerg 10,871 Posted May 14, 2020 Maybe run a temp relay to the starter so you can eliminate so much current going through the ignition switch. The starter solenoid takes about 8 amps to pull it in, a relay takes about 20 milliamps.
