Please Help
 

My 1988 Porsche 944 (non-turbo) is haveing an attitude problem.

This morning I left home to go mail a parcel at the post office a quarter of a mile away from home. On comming back home, my 944 wouldn't start! I turns over... alright but wouldn't start

I have taken it to the repair shop 4 times now and mechanics don't seem to know what the problem is!!!!!!!!!!.. quess work has cost me a new Airflow meter, Engine tempertsuture sensor,
Air filter, and labor all totaling $1500.

Any ideas!

NB: what the car finally starts hours after a leave it alone, it starts like nothing ever happend to it, just to freeze-up again a day or two later.

PLEASE HELP!!!!!!!!!!

when it will not start, are you getting any spark?

Yap.. got new spark plugs, distributor cap, spark-plug wires, rotor and all the belts are relatively new.

how did you verify spark was actually getting to the plugs?
