Good advice here. This JUST happened to me with the same symptoms. It turned out to be a bad reference sensor. $55 shipped from pelican. Good luck!

How would I go about doing the jump on the DME relays?

EDIT: When you talk about dme relays, is there a specific relay your talking about or just one of the relays in general?

Ive had my 944 for a year now and im 19, so Im quite new to the whole 944 ordeals...

My car has the fuses and relays under the steering wheel, and I have no idea which one needs to be tested...

If you're getting fuel when you try to start the car you don't need to test the relay. It's working properly.

So under my circumstances, where do I go to next? I have checked the fuel, I have fuel.
How do I check the air flow?

re:

do yourself a favour!
remove the fuel pump relay, replace with known good one, or just jumper the contacts to test.
i went thru this recently. the solder used on these relays was a poor mixture, and leads to either cold soldered joints, or the solder will actually crack. this happened to me twice ! when i inspected the relay, i could see the solder was cracked all the way around the pin.
very frustrating. my friendly sparks took all the old solder off, and re made the joints with modern/better solder. he has guaranteed the relay joints will last the life of the car !!
good luck!

But I think mt fuel pump relay is fine. The fuel pump will start up just fine when i turn the key to the on position. Doenst that mean the fuel pump relay is good?

Someone here mentioned the reference sensor. If your getting spark,then it's most likely a sensor.

So Im not getting any spark at all. I took of the distributor cap to see how the contacts were looking like. They were slightly corroded, so I cleaned them. I then tested to see if i was getting voltage through the distributor cap. From the center wire that goes to the cylinder by the windshield washer reservoir, it had a voltage of 12 volts when the key was in the on state. Then checking the rotor to the distributor cap that was off, I wasnt getting any voltage. Does that mean I need a new rotor or distributor cap? To also note, the spring loaded piece of carbon in the distributor cap seemed to be in good shape.

I also was wondering when a spark plug is removed and you turn the engine on, should you be able to see/smell gasoline? I couldn't see or smell any gas.

Sorry to fill you guys in, I though I replied to this thread. All it was was the DME relay... I overlooked it at the very beginning and went to the worst case scenario... Remember guys and gals, check everything!
