First- without the help of Admin Andy and Timothy nd 28- my 1975 1.8 L jet would not be on the road. Thank you to everyone who helped me.

NEW ISSUE I NEED HELP FINDING- WHY CAN'T THE ENGINE CONTINUE TO RUN?

The engine will start. (I was having a problem with the ignition not turning the motor over- but I think I solved it with a fuse and a relay problem). Now, she starts every time, but then stops after a few seconds. It appears either my fuel pump is out or I'm not getting enough electricity to the pump to run it.

I have installed a MSN fuel pump. It is high presure and worked perfect out of the box. I put about 2,000 miles on the car before this mystery started.

I've checked the in-line fuel filter and it seems fine. (I do live in Southern Oregon where during the winter the area is forced to run oxigenated fuel that is known to cause problems with older cars- but since she starts just fine I think my injectors are ok.)

I've pulled the relay apart and all contacts seem to hit just fine.

My questions:

1. Could a new fuel pump go bad this fast?
2. If I'm not getting enough electricity, or have a bad end, where in the world do I find the wires in the engine bay? The pump is connected with a brown and a black (ground) wire.
3. Could it still be the relay?

Thanks in advance of to everyone who might chip in advice. I am not experienced checking voltages- but am willing to learn.

The problem with this car is: I've got the body in great shape, put a new interior kit in, and have thought about selling it to finance either an SC or a motor for my 365c, but I'm really starting to love this little car. Or as my wife calls it: The Hot Wheel.

Thanks,

JAA

L jet cars will do this when the AFM is not connected or having issues.
