Problem 1: The external fuel pump is noisy and doesn't shut off with key turned to off position - had to disconnect the battery.
Any thoughts on what causes this? Did I burn up the pump when I ran it with no gas?
Seems to make the same noise when there was no gas and when there was gas. Could the in-tank pump not be working and causing no gas to the external pump? I don't know if fuel pressure got up to 39 PSI as I don't have a fuel pressure gauge, but I could hear some 'girgling' at the fuel pressure regulator while the external pump was still running just prior to when I disconnected the battery.
How to verify fuel pressure?
And I thought I smelled some gas fumes in the engine compartment. So, it seemed like it was getting some gas.
Problem 2: The sending unit/sensor that sticks out the side of the block between the #1 and #2 exhaust ports is broken and disconnected.
Could this cause a no start as well? I know there is a relationship between the oil pressure switch and engine start. This may just be a water temperature sending unit, though. Correct?
I have not verified spark or injector pulse, yet.
BACKGROUND:
I just began working on my factory stock Cosworth Vega #203 after sitting for the 6 years since I've owned it.
I bought it non-running and I can't remember what was wrong with it, but it sat in a field in southern Washington for years prior to my purchase.
Odometer shows 34K miles - don't know if it is accurate. But car is well-worn - paint faded, rust in battery tray/frame rail area.
The PAIR system was removed by a previous owner.
I have zero experience with the Cosworth Vega DOHC EFI engine. But, I know a little bit about the various components of the EFI system and how it all works in theory.
Anyway, thought I would try to get it running since I swapped out the ignition lock cylinder (lost original keys a LONG time ago. )
Need some help by the experts here.
Before attempting to start:
Oil looked good in both color and level - amazing!
Radiator was bone dry. Added water.
Pulled spark plugs - they looked OK. Re-installed. They are not AC plugs - some Japanese brand.
NOTE: Previous owner had put anti-size on the threads, so they loosened with no problem. Good? The plastic spark plug boots have white marks on them - 1 mark for cylinder #1, 2 marks for cylinder #2, etc. Is that from the factory?
Installed new battery. I could hear the noisy external fuel pump cycle on and off when I turned the key to on and then to off. Seemed like external fuel pump is working. All good.
I then attempted to start the motor. Engine cranks but no start after several attempts.
Oops, forgot to add gas. Not good. Added 4 gallons.
Attempted to start it again with gas in the tank this time. Cranks, but does not start. Not even close to firing. But, I thought I heard a faint hint of a cylinder or two trying to fire - perhaps wishful thinking.
