944 Won't Start, Good Spark, Good Fuel

Recommended Posts

I have a 1985 Porsche 944 that won't start

All 4 plugs spark and there is fuel at the fuel rail.

I tried the following.

Gas strait in to the throttle body

Gas strait in to the cylinders via the plug holes

The car was running fine until I hosed off the engine and used engine cleaner

I checked as many connections as I could find to make sure they were dry.

The tach moves a little tiny bit when cranking.

Any ideas?

... if you have spark and you have fuel what are you missing???? that's right - air! Check the MAF and intake.

A similar thing happened to me - it ended up being the intake boot had a big leak - check and make sure it's conntected nice and snug on both ends. It could still be your MAF.

If connection from the ignition coil to the distributor cap is not working, that could cause a non-start issue as well.

My 944spec buddy told me that 99% of hard or non-start issues are related to the ECU...

Good Luck
