NO SPARK 900 1991

posted by  someone claiming to be paul on  Fri Jan 17 11:04 CST 2003 [RELATED]



I was driving my 91 940 se turbo just die The car cranks but no spark, 0 v across coil, remove neg terminal get 12v, traced back to power module on drive side fender power on 1 and 4 of connector. Seems to be ok. Are there any other connectors prior to ecu ?

Leading back to ecu and am having trouble locating (unit above brake ?)There is another module on dr kick panel

Not getting any codes
When I run fuel diag no sound only air valve under intake manifold. I think injectors shold fire during test
Is there a relay or fuse that would stop spark?

Any tips on troubleshooting ign. system ie good test piont for rpm sensor, method to see/measure signals to/from ecu, pin outs for ecu etc.....

Thanks
Paul
