No start condition - 1988 90Q

[dgraber460 at aol.com]

 Your diagnostic was great, with one thing I would check further.
You say it smells of gas, but you didn't specify it was getting to the cylinders.
You might smell it cause it's going elsewhere. If it will fire on starting ether, then your not getting fuel to its rightful place.

Subject: No start condition - 1988 90Q


In  need of help again, my son's 90q is out of commission again.

Here is what he reported:

when trying to start the car, at the first or second crank he heard a bang (a 

snap, something sounding mechanical) and smelled something weird under the hood.  

The smell, he said, smelled of friction.

The car kept cranking, but no start.  Came back home on a flatbed.



Here is what I checked till now:

- starter cranks the engine

- timing belt is OK

- valve train is moving (took rocker cover off to see if sprocket is not 

sheared)

- has good compression

- timing belt alignment is OK (crankshaft to camshaft)

- distributor turns

- smells of gas when cranked

- seems to have spark (checked with wire touching enging block)

- coil resistance checks out OK

- Hall sensor works (blinks a diode)



Where to look next?  I'm going to blink out error codes tomorrow, mosquitoes 

chased us out tonight.

TIA



Radek
