Porsche_993

I was driving my 1995 993. I think I ran out of gas even though the gas light did not come on as it did in the past.

Car stalled and then started momentarily and then shut off again. Filled up 2 gallon of gas and car still will not start. Had to get the vehicle towed. Never had any issues with the car before. Any idea on the cause?

I opened the engine compartment and noticed a hold in the rubber / plastic intake connected to the air filter. See picture.

Does any know what would have caused this or if this is related to the car not starting.

The broken air duct (fairly common at this age) has nothing to do with the car not starting/running. If you're certain the tank has fuel in it, try a new DME relay.

Andreas is spot on, I reckon.
DME
Part number:
993 615 227 01
Always carry a spare!

The DME relay is located in the fuse box in the trunk, underneath the carpet on the passenger side, right beside the hood hinge. Undo the two clips that hold the fuse box lid in place, and remove the lid; the relay is located as circled below.

BTW that broken shroud duct is part #5 in the diagram below. There are two versions of the part, the one starting with 964 is for 95 pre-varioram cars, the one starting with 993 is for cars with varioram. Easy install, 3 bolts to undo, slide out broken part, insert new, done. Part is available from Sonnen, Sunset, Pelican and others.

You should not run at a low fuel level intentionally because you risk picking up sediment at the bottom of the tank and possibly overheating fuel pump caused by pulling in air, fuel is the coolant for the pump.

buy two. keep one in the frunk.

If you really did run it out of gas, it'll take a little cranking to get fuel pumped back to the engine. Just don't do the cranking all at once -- do a few 5-second bursts so you don't overheat the starter motor.

Don't forget, the fuel pump does not run continously when the starter is engaged; it operates just for a moment until the engine starts.

You will either need to jumper the FP (DME) relay, or be patient and keep cycling the key to the "on" position several times until the pump has filled and re-pressurized the fuel rails.

Thanks for that info that is good to know.

This. you can have a buddy turn the key for you with the frunk open so you can hear the fuel pump do it's gig.

Two things. Ya let the gas get low enough to run dry? Bad juju!!!! Don't wait for an "idiot light" to tell you to get some gas. And you scared me stating the rubber fan shroud duct was connected to the "air filter". The above advise should help ya get er started. Good luck

So it has been 2 days and we have not heard back from you. Did you get the car started? What was the problem?

Grapeape

I second Tom. What did your mechanic find? I always look back for a successful ending to the story. The OP's for threads like these should add their value by providing closure. It is more valuable than a thank-you to those taking the time to help trouble shoot and provides a complete picture for future searches on issues.
