Toyota MR2 Message Board - View Single Post - Mark1-no start and no check engine light?

mr2tim · 09-08-2008, 08:20 PM

In need of some advice....

Fried my 4 wire o2 sensor wire on the exhaust manifold..and fixed it.

Tried to start the car and didn't have a "check engine" light, tach appears dead, & no measurable electric at coil?

I have replaced the ecu, coil and igniter, all the relays in the engine compartment, sc relay, cuicuit breaker, the ignition switch was checked ok.

The power checked good going into the wire at coil/ignitor connector but not at the coil? (replacing coil didn't matter)

Since I don't have the check engine light I can't access the diagnosis system?

Any ideas out there?
