98 S90, Cranks won't start!

Post by DCamp »

I was driving to work, exited off highway and stopped at light. S90 began to idle/diesel/ no power. I was able to coast to work.
I have checked compression avg. 132psi, have spark, have fuel at injectors, replaced crank sensor, replaced ECU, cleaned cam sensor, new plugs and removed cat/exhaust no start. Timing marks are dead on! Assistance is much appreciated. 2.9l w/165k miles. Ignition Control Module? IAC?, MAF?,

Cheers

Are injectors 'pulsing'?
If no, then check for the common (+) power supply to injectors (I am assuming you have the Denso or Motronic arrangement with switched (-) ground from ECU). If OK, then: Is your Fuel Pressure OK?
Example of Precision: Measure with a Micrometer, mark it with Chalk, and then cut it with an Axe.
Disclaimer: We (very) seldom do that

How is your spark? I had a coil pack quit on me once and it idled pretty crappy, and I limped it home. Check for spark on all your plugs. With new plugs do you see any wet ones? Any codes?
