Question type: Maintenance & Repair

I have acquired a  1984 porche  928 cp v8 that had extensive mechanic
maintenance compleated prior to  being parked in dry storage for about
the past 11 years. After some  general minor clean up, i was amazed with
the overall good-great condition of the hoses, wires, ect.  The tune up
parts and all fluids looked brand new and fresh. however for my  peace of
mind, i still replaced all the fluids, spark plugs, fuel filter, and battery . i also
dropped and cleaned out the fuel tank. as well as cleaning up the starter
connections. It turns over but does not start up. i double checked my
connections and  made sure my battery had full charge. however i still am
experiencing the same  problem.  I would like to know how i go about
checking to make sure im getting spark, or how to check to insure  the fuel
delivery. as  i am thinking maybe i have a issue with wires of my fuel
injectors.  i would greatly appreciate any advice and/or ideas  on which
direction to go in regards to resolving this issue. Thank you

Check for spark by pulling a spark plug wire. Put a spark plug in it and ground the outer part of the plug to a metal engine part. Have someone turn the engine over while you watch to see if there is any spark. I bet the problem is with fuel delivery though. Did you replace the fuel filter? Blow out the fuel lines and make sure the fuel pump is working?

Could be a bad crank position sensor
