i put another engine in it winds ova but no spark

[oldcorollas]

swap in the ignitor, dizzy and coil off the old motor. are they the same? is the dizzy compatible with the ECU?


i think the very first thing you need to do is to go to "Them" and ask "Them" what "They" think.

if They gave a rooted motor, They should fix it up for you... did you ask Them if it was a straight swap, all electrics the same?

pull out your manual and check that the dizzy is the same...

the coil should not be grounded anywhere except through the igniter.

you havent put a wire from the negative side of the coil to ground have you? this will stop the spark all together.

ok,
i got a new coil today still no spark.The positive and negative poins on the coil have power. i tested them with a circuit tester they both lit up the injectors were pulsing,but the main lead out of the coil had no power at all ,its the lead that comes out of the coil 2 the dizzy.
i aslo got a new ignitor,
still no go........

there's your problem.. me thinks agree with slide86 that u grounded the coil somewhere..

altho if that's not the problem, power going into the coil is good but still no spark happening = rooted coil or rooted lead or rooted spark plug.

try this.. connect the coil to one lead and connect one spark to that lead. (put the plug on the valve cover or body) and crank. is there any spark at all?? that proves my suggestion.

at this point, the next step would be to check your ignition and ECU... and if that fails, my master would say "bring the petrol and give me a match i'll fix it right up"

how could i check the ignition and ecu.
also what fuses could blow to make this happen

[roadsailing]

take the car to a mechanic or a sparky.

do what everyone here has suggested and post up results of your trials so we can help you further...

otherwise u're asking for answers without the right question.

start from the begining again
dizzy - did you try using the old one?
coil - bench test it just to make sure or do that spark plug thing i suggested
leads - again u could try this on another car or bench test
timing - well if you have no spark this doesn't really matter but are your cams matched up with your crank and dizzy in the right position?
ignitor.. ---- so u've got a new ignitor.. that's good for a start..

fuse / relay - focus more on the ignition part. Power coming in? power going out?
then to a further extent your ignition barrel and everything it's connected to? this is done with a test light and multimeter

ECU can also be tested.. simple diagnostic test or even just testing the signals to see if it's doing what it's supposed to be doing?

ok,
The positive and negative poins on the coil have power. i tested them with a circuit tester they both lit up

Check this again while cranking the engine.
With the test light on the negative terminal, crank the engine. The test light should flicker.
Post up the results.

Check you have 12V to the coil when you have ignition turned on. The other way is to wait until night, and do the following: unplug the feed from the coil to the dizzy (at the dizzy end), face it towards a metal object (motor) and try n turn it over. If you have a lightening display, your ignition is fine bar dizzy. If you do not, you have a problem in either the coil itself not giving output, or the trigger wires from the coil to the dizzy are not working properly.

Sorry, forgot to mention you could check if your ignitino relay is clicking, your fusible links are ok.

A common mistake also is - did you reconnect the earth cable from the motor to chassis when you put the motor back in???

blake

[pinkky]

yeah might have to do that big $$$$$$$$

[Robbos_Toyotas]

did you check your earth strap??? from motor to chassis?

[pinkky]

no i didnt connect any wire from the motor to the chassis,
to earth what wire..

[oldcorollas]

so how does the starter motor send it's current back to the battery if there is no connection between the motor and the chassis... electrical conection that is?

[limbo]

Did you put any of the earths back?
If the motor is not fully earth its not gonna start.
Make sure all the earths that were on the original motor are somewhere on the new motor.
Also did you earth the battery?

[Robbos_Toyotas]

no i didnt connect any wire from the motor to the chassis,
to earth what wire..

it NEEDS that wire to start bro, i forgot to put mine on when i put the v8 in the supra...i had the same problem you are having until my dad clipped me behind the ear!

connect a big assed strap to the body from the block and you will be fine

[pinkky]

well when i tryied to jump start it i connected the eartyh to the engine and the power cable to the positive terminal and it wound over. so it would of been earthed
