Re: Fuel pressure on 944

Thanks for the tips guys.  I finally had time to check out the fuel 
troubleshooting steps.  I found that the fuel system is working correctly.

I have good flow, good pressure and the leak down test was also good.  I 
also checked for proper signals to the DME.

So I looked at the spark next.  I pulled #1 spark plug and found it only 
spark about every 5 sec...not good.  So I looked at the coil next and
found 
that the resistance is good on both primary and secondary windings but
when 
I use the jumper trick I get very little to no spark.  The only thing I
can 
think is that the coil is bad although the resistance measures good.

I'll let you know the outcome once I get a new coil.  Just one more thing
to 
buy.
