Car died...help

I left the house, got about a mile from home and she died.

It has been cold here, today mid 20's. I just started and went. Was going through the neighborhood, it seemed like I hit a bump while crusing in 3rd and lost all engine power, although the radio and electric seemed unaffected. I took it out of gear and tach went to zero and it wouldn't restart. It turns over great, but doesn't seem to be sparking?

I am going to try to get it home later today.

does anyone have any ideas?


thanks in advance.


Mark

Have you checked for fuel flow? Could be as simple a a fuel pump relay or fuse...

Assuming it is the 86 911, could aslo be the DME relay. Could also be the wiring in the motor.

Simple check is to find a hot wire on the trunk fuse box and run a jumper wire over to the fuel fuse.

Thanks for the replys...

it is the 86 911.

After it died, I jiggled the spark plug wires to see if they were loose and they didn't seem to be. I tried to crank it a few more times and again it turned over fine but nothing. I did faintly smell gas as my wife was picking me up. I assume it is getting fuel but not positive.

How do I tell if it is a DME relay and whats the approx. cost to replace?

When you say the trunk, I assume you mean up front?

Thanks in advance...

Mark

The relays only cost around $40, and it's a good idea to keep an extra with the car because it seems they all go out eventually. If you've got a buddy with a Carrera nearby you can switch his relay into your car and see what happens. The switch only takes 5 min. I think there's a way to bypass the relay but I've never done it.

From memory the DME relay on the 86 is under the driver seat with the DME (motronics brain about 5"by 5" by 1.5").
the DME relay is a black squarish box about 1.5" square?
Just plug and play.
The fuel relay is under the front hood (bonnet) and is on the left driver side and is usually under a cover. There are 3 or 4 relays which are round and either black or red again about 1.5" in diameter. again just plug and play.
I had the fule pump actually die on mine about 10 miles from home.
The fuel pump is under the car in the center about 2' back from the front, aft of the front wheels.
If the fuel pum p is working you should hear it buzz quietly when you turn the ignition on but before it turns over.
Let us know how you get on, good luck

When the DME Relay on my 86 Cab went out a few months ago...the car would run for a little bit, then die after a few minutes. Replacing the DME solved the problem.

Note: My car would start and run...then die. Your symptoms appear to be different.

In the Carreras, the DME relay is the relay for the fuel pump also. Also, be sure to check the fuse.
