Ok,
So my 73 was running great until it slowly started to go down hill. Car would not start after it was running/driving for a while but the next day would fire right up. Recenltly changed the oil that was completly diluted with gasoline. WTF??

Read this thread: http://www.914world.com/bbs2/index.php?sho...=312907&hl=

It all applies, even though that's a 2.0. If you check some of those things and give us feedback we can help narrow it down.

Gas has washed past the rings and into the sump. Good thing you changed it; gasoline does not lubricate like oil does. This happens any time the mixture is rich enough that the engine almost doesn't run.

Things to check: Fuel pressure, disconnected wires (especially head temp sensor wire), MPS that won't hold vacuum, unplugged hoses...

--DD

Thanks a whole lot!

Thanks I will check that out.

Check mps vacuum first.
Pretty easy to do and good chance that's the issue.

Ok, so fuel pressure was 27 psi.....car starts with fuel pump disconected from the relay box after it has been primed...wtf? lol

Fuel pressure is not the issue then (it's probably low by a PSI - I think 28 PSI is spec).

Are you saying that you can disconnect the fuel pump relay (or connector) at the relay board and the car will start/run after initially turning the key and priming the fuel pump? Please explain in more detail. How long does it run that way? Once you prime the pump the fuel is going to be pressurized for at least a short period of time even if the pump isn't running, but it will bleed out quickly.

Not sure why you disconnected fuel pump, but you still need to:

1. Verify MPS holds vacuum.

2. CHT is working properly and is connected to wiring harness properly.

3. Try with CSV disconnected.

The car runs for 1-2 seconds after being primed and then diconected.

Ok, that sounds normal then. Your fuel system is pressurized when you prime the pump.

If it goes down hill slowly ........ release the hand brake
