6G Celicas Forums

Hey Brenton, well, my issue is have no spark from discharge in coil to cap, I have power to coil + and - but I have no pulse when cranking, same with injectors....I hear what your sayin about Tweak, he does do awesome work, very impressed with how clean and perfectly routed my harness is,checked every wire at ECU, and all is correct....
Pulled distributer off and tested, G1, G2 checked out at 154ohms and NE+ was 190ohms and of course G- is ground, that I tested from, and from what I can tell, it is in good shape within ohm spec, today when home from work will hook coil directly up to battery to see if I can get discharge to arc...then I will know if it's shot or not. If nothing comes out.....anymore thoughts man??

did u check the ignitor if u have power to the Distributer coil and your ignitor is good check your relays tho's will really get you but i really think its the coil the cap rotor botton relay or ignitor try to get a another Distributer the whole thing see what happens i really have that problem alot when imm working on peoples car those coils gooo outt alll the timeeee and i put a new one on and bam it starts righttt upp but i really think it has nothin to do with the wires tweak has been doing them to long to mess them up wat gen do you have i think the 3rd gen has a cam sensor it should still spark if its bad the car just wont be in time take the cam sensor out and try to pick up something metal with it if it doesn't pick up anything its bad if that is the Distributer coil that came with the engine and you never got a new one im almost sure that that is your problem

are you saying you don't have pulse signal to distributor cap and injectors ?

3rd gens do not have a cam sensor..(well, technically, the do, but it's part of the distributor.

Yes, when cranking, have no pulse signal to cap......just a constant power,

it might be your ecu if your not getting a signal call tweak tomorrow and ask him can he look at your ecu this is why i got a caldina i have c.o.p's and dont have to worry about the Distributer and ignitor just my crank sensor c.o.ps and cam sensor

and injectors ?

if both systems are affected, I would look into the COR

Yes, no pulse at injectors either.....

so looks like either something with the ecu or dizzy. Correct? The injectors won't pulse unless having a signal from the dizzy.

yep same thing i told him

Does dizzy stand for distributer.....sorry, had to ask, is that what you mean though, if so Brenton told memto replace it, can't I just replace the pick-up coil inside, or should I just get a whole new one.

I will say this to you guys, I had spark before harness was sent out........I get harness back 2 months later, and now no spark.....think that's why it makes this so much more confusing, because it's hard to believe a part would just go on my car in that time the harness was gone, I guess it's because of coinsidence, that I'm suspect of the harness, cause the car would barely roll over twice before firing, now nothing????????

uve took the harness off make sureeeeeee u ground those ecu cables in a gud spot put them back where they were wen u had it on there before u sent it and yes u can replace just the coil inside if u really wanted to

What ECU cables to ground?? Wait does ECU need to be bolted down to centre console on bracket, to be grounded???

the ecu does not have to be bolted in.
here are the specs for the 3rd gen distributor.

no there are cables that cum out from the ecu to the engine bay they should be grounded to the block on the caldina they are under the intake man i have no idea where they are on the st205 can sumbody please help him out with a st205 he needs to find the ecu ground cables


and the not cables sry i just say that for wires but they are wires they come out of your harness they should be brown unless tweak used a different color but im sure they are still brown

Now that you said that Brenton, I did mount a wire behind the intake manifold, on a 10mm bolt the wire had an end that excepted that bolt, n screwed it tight to back of manifold. From the harness

Ok just tested coil with battery + - and had a very very small spark on coil wire ( discharge ) end, to screwdriver, is this spark supposed to be big n bold, or barely able to see it????? Cause that's what it was...really had to look for the spark????

yeah try to go get a new coil and see what it does i really think that is your problem

K man, I am gettin one tomorrow.....keep my fingers crossed, the scary thing is, if this doesn't work, I don't know what else it could be????
