I've had the car at the body shop for quite sometime -- they've
never had an issue with it firing up.

Sure enough -- they are almost done and they went to move it yesterday and
she'd crank all day -- but no start.

I happened to be out there last night picking up a race car -- so I gave it a try with no luck. Cranks well, just doesn't even hint at starting.

This car has always fired on the 2nd crank if the starter engaged. I did have an issue at one time with the tranny sensor -- but then there would be no starter.

1/2 tank of gas per gauge -- and I shot some starter fluid down the intake
a couple times -- then tried to start it -- I was by myself, so couldn't do both at same time.

I didn't have any other tools or info with me at the time
and the body shop has limited hours -- so not like
I can get out there over the weekend.

I'm guessing that because the starter fluid didn't help -- that it must be spark -- but
I didn't have a way to check that last night.

I really don't want to have to trailer it home -- figure it out, then
take it back to finish the last of the body work.

However at home I can tinker -- as time allows. There I've got to be more tactical.

thoughts?

thanks,

The timing system is dead simple. I'm surprised that was the failure instead of the fuel pump.

Apply a timing light and see if that's really not working. Perhaps a visual inspection will show a loose wire or something.

Quick follow up Q:

Does the tach bounce on a 928 just like it does on a 944 (although it has a DME and my 928 doesn't)

The tach bounce is our simplest debug gauge on our 944 race car.

thanks,

I've never noticed if it does.

surprised they don't have any wheel dollies for situations like this. maybe you can rent/buy a set?

replace the green wire

Green Wire:
Is this the wire from the 14 pin to the coil input?

Is there a way to check this in situ -- after showing from the coil there is no spark?

thx,

Mike

98% of wont starts are green wire failures,
if your wire is original or old then replace it,
it should last another 25 years or more
