I have a friend with a 7MGTE waiting to swap into his Supra, I'll see if I can get out to his place sometime soon and check out the coil pack wiring for you. When you mounted the coil packs, did you attach the grounds coming off of them too?

Of course i made sure everything is well connected and earthed and yea they all are, i already tested all voltages n keep getting 12v means its connecting but no spark or i reLly does but wrong wire!! that y i need help by give me closer pix of the wires or just tell me off of any turbo mk3 jus lik my pix above

[btwilson86]

Ok, here are the pics I could get. Coil pack connector,individual coil connector, and the coil pack ground. I just realized that the first pic is probably useless since I don't have one of the wiring harness side, so hopefully someone else can post a pic of that one

Hi! -Had a close look at your ground wire , seems a bit loose, so could you be suffering bad starting? . Also, the ground from the plate should be connected to the cylinder head as the cam cover is mostly insulated ( sits on a rubber gasket and held down with rubber washered bolts ) .
May I suggest that a bulb and wire or a multi-meter be used to confirm continuity of the wire and the curcuit or plate is fully earthed .

Interested- the upper intake is currently removed on that engine as we are in the process of swapping a usdm wiring harness on it, so that's why nothing is really connected atm.

Dawg- its from a turbo, why would i take the time out of my day to send you pics of a N/A? Like I said above, I don't have a pic of the harness side of that connector so I can't tell you what wires connect to what. There are hundreds of people on here who actually own 7mgte Supra's (the one i took the pics from isnt mine), one of them will have to help you.

Hi! -thanks for your feedback , just trying to assist , my car wouldn't start after overhauling following a BHG , so I know how frustrating a non-starter is , got it going eventually after finding my ground wires were not re-connected underneath the intake manifold and , the grounding wire was very corroded and only connected by 3 strands at the coil plate , thats why I made a new one .

Yea your right i didnt noticed it until later last night but already so late i had to grab sleeps lol was lazy edit mine ,but you are right its turbo now i got it correctly..

Blue/redto black
Blue/yellow to white
Yellow to green
3 tan wires to black n orange
jus made me 2 ground wires jus in case lol

Hi! this is a picture of my coil pack earthed ( grounded ) out , is yours the same? -very important - no sparks without .My car is a '89 7mgte. MA70. Also-check that all of the earth ( ground ) wires are connected UNDERNEATH the inlet manifold , you'll need a good mirror to see them -theres loads of them .
