1990 Eunos Roadster Starts then dies.
Hi there,
1990 Eunos roadster, perfectly stock.
Now's the time for my winter car to run. I've parked it last april and when i came to my storage to start it back, didnt start.
Well... There's no good way to say this.
1. I start the car, it automatically dies after 2 seconds.
2. I Have good spark on 4 cylinders.
3. I Have good fuel pressure, i have injector pulse on startup and then my car stops the injector pulse and then it dies.
4. CAS is scoped, signals are true and sync. Power and grounds are nice, tested with a lightbulb.
5. Coil is powered ok, Power and grounds are nice, Tested with a lightbulb.
6. I didnt have RPM at first, but i fixed a broken wire (That i see from ECM to Ignitor and everything seems nice so i bypassed it) So i have Rpms.
7. Every Signal to and from Ignitor have been scoped, i have ok signals and everything seems to move. Power and ground also tested with a lightbulb.
8. Ignition Switch is brand new and wires going to it have been tested and cleaned.
So my car cuts the injector pulse so it dies. If i start the car and reswitch key On/off repeatedly like a madman, it resets the startup injector pulse and it 'Runs'.
If i try to start my car after it died ( from my key already released from START and still to ON ) It doesnt fire up at all. No injector pulse.
quite strange.
Any insights?
Thanks
