The saga continues sort of. I found out why the car was stalling. I think
I changed the oil pressure sensor at the distributor and discovered my oil pressure was very low. Why because I was two quarts low. The old sender said I had 40 or more psi. The red bar came up as soon as I stated the car.
but still mo pump prime on start up.

:
are you getting good fuel pressure when you turn the key on?? does it stay up?? you haven't said what your pressure is...

So I am following the directions in chary A-6. It says test light on Terminal E and on terminal B no light fix open ground. So I decided to run a wire for terminal B to the battery meg. No test light. Then. I probe E to ground no light . So I lost E. Then I run a wire from battery to E and a wire to battery negative. I connected them using the test light. Got SMOKE. Is the connector causing the problem?

I bought the pump in February of this year. It has 1000 miles on. Plus if the pump were no good the car would not run,correct?
if I prime the car with gas it runs fine. In fact now that have changed the oil pressure switch I can ride the starter and it will start and run,well.

Can the connector cause the problem. here is why I ask.
According to the shop manual terminal E of the connector is always hot. Terminal B is a ground. So I take my test lamp and go from E to B no light. Then I run a ground from the battery to terminal B and try the light. I get smoke, yep smoke and I loose power at terminal E. I can start and run the car. I assume through the relay. But all I can figure is that the connector is causing shorts. Is that possible?
thank you.

The connector could be a problem, but first let's check a few things. Do you have an ohmmeter? If not, go get one. They are very helpful when looking for electrical problems. Use the ohmmeter and check resistance from B to a known ground. It should be very close to zero, not infinity. If you are not seeing zero, then you need to fix that ground wire. Once B to ground is zero resistance, then check B to D, B to A, and B to E. Those should all be infinity, not zero. Also check C to D, C to A, and C to E. Those should all be infinity, also. If B and/or C to A, D, or E is zero or anything less than infinity, then you have a short in the connector somewhere. Another check to do is on the relay itself. A to D should be zero and A to E should be infinity.

If you don't have a ground on B, check G160, Fig.8A-19.. FYI the 84 DOES NOT have a cold start injector..

update
Remmebering that I had power at E, last week, and lost power after I tied to go from E to B. I do not know what is going on.
I went to the fuse box and discovered that there is no power on the fuses marked Crank, Inst and FP.
I can start and run the car. Just ride the starter a little get 5 or more pounds of oil pressure and it fires right up. But I would still like to have everything working correctly.
thank you for the help.
