[SpeedRacer]

ok, trying to start my 4age tonight, will crank but not spark. took the coil -> dizzy ht lead off and thats not sparking, pretty sure coil has power, guna get an LED to check ignitor tomorrow.

running a Link LEM, SR20DE ignitor and standard coil dizzy

anything else ive forgotton?

grounded ignitor?

grounded ignitor?

SR20de igniter has an earth wire. the toyota igniters use the case as an earth ( even though they never show that in a wiring diagram)

Do you have a remote or laptop connection for the link?
Are you getting an RPM reading on the display.

To test the wiring.

Unplug the ECU.

Turn on the ignition.
Use a test light with about a 12v 4watt bulb.
Clip the lead onto a 12V pos supply.
touch the probe of the test light onto the IGN1 wire in the ECU plug,
(the wire that goes to the igniter)
the coil should spark as you make and break the circuit with the testlight.
if it does it's most likely a problem in the way the dist is connected to the ECU, or in the settings in then ECU.
If not, then you have a wiring, coil, igniter problem.

just to make re enforce,
do this test with the ecu unplugged.
Do not probe power into the ECU. Probe it into the plug you have pulled out of the ECU.

ok, put an LED on the injector and it flashes away, so im thinking its the coil or ignitor

anyone tell me which wire does what?

the coil is the TVIS non round one
I *think* the SR20DE pinouts is:

white: coil
Green ecu
black gnd

ok so heres the latest:

LED on injectors and it flashes then blows (no resistor )

LED on ignitor and 12v, blows straight away (no resistor )

which leaves the coil. that should all mean the coil has facked itself and i need anoher right? is there a way to test the coil to make it spark?, did the thing u suggested matt ad nothing happend.

any update on this man?

ive got same problem with my 4age, but got power to coil but none to dizzy and 1 of the wires to igniter is dead.

Coil was wired wrong, have a look at your thread, i just replied.
