I disagree that sporatic problems possible rule out relays. You jumpered them both and you are getting the no start right?
Ill try to look up more info on the resistance you are seeing at the coils

Dan,
Have you tried jumpering the fuel pump relay? Do you hear it running? 87 to 30.
Did you three-way jump the fuel injector relay? Three-way wire 87 + 87a to 30.
If you haven't tried, do this and try to start the car.
I have a well-worn 84 5 speed that has had intermittent function from its old relays. (in fact, I've had a brand new relay click in and out on the highway when temps got down in single digits). Never underestimate the dodgyness of relays.
Also, does your car have the factory alarm. Or is it bypassed?
If not bypassed, go thru the ritual of closing hatch and doors, lock then unlock with the long key and try it. You could have an intermittent situation combined with a driveway alarm situation. Its happened before.

Craps, I did not jump the FI relay 3way!!! ![soapbox](https://rennlist.com/forums/graemlins/soapbox.gif)
But the pump did work......
Zoltan, the only way to test the relay is to have enouf amps to make them click and my colegue did not have the amps needed.
I called at different places to have the relays checked and it seems that no such machine exist!
But the pump IS wizing and there is gas at the rail.
I even opened tem up and cleaned the points, the rest looks ok to me....
Will go jump the FI relay and will get back to you guys.
Thanks

Thanks to everyone who helped me out, I was a zero when it came to electronics.
I just saved another bondle..... I love this place.

Conclusion : Do the jumps(properly) before anything else....
Can't trust the reading for the coil and resistors...
Nock on wood, it was the FI relay.

Stop the press
It turns out not to be the relay.
Got another relay and still the same thing, no start.
So I rechecked the voltage @ the socket.
Ignition off or on, socket 3 as 12v (3,4 and 5 are for jumping)
Ignition off or on, socket 7 as 0.04v - according to the other 7 I have tested, should be live with ingnition !? Please confirm...
Ignition off or on, socket 2 as 0v
On the relay 3=30 4&5=87 7=86 and 2=85
Started to dismantel the board, anyone as a runtrough for that job?
I can lift it and bend it my way to take a look and it seems that there is a somewhat loose wire where the FI socket is....
Anything I should watch for or do..yes the battery was disconnected.

BTW Sharkskin has the best central panel article ever. Search and you'll enjoy it.
Good luck.

Well, I'll be a MONKEY'S UNCLE.
![](http://www.cinemaretro.com/uploads/PLANETAPES3.jpg)
Just to be sure before dismantling the fuse board, I got 2 more new relay.
Low and behold, the dam car runs.
To be sure it wasn't a fluque(sp) I tried and old relay and no start.
So I put back the new one and it runs.
Got sidetraked with those voltage/ohm reading I got...
But now I have rugh idling and some misfire/hesitation at take off.....from messing with the electronics
![surrender](https://rennlist.com/forums/graemlins/surrender.gif)
Idle is around 700

And what is the prossedure(sp) for checking that baby? ![Confused](https://rennlist.com/forums/images/smilies/confused.gif)
Ok, today I got a new coil and I still have rough idle misfires.
Took more reading and the resitor 6ohm is at 1.0 (should be less than 0.65) and it's hot to the touch after only 1min. running. Is that ok?
4ohm resitor is at 0.8 (should be less than 0.4).
Can anyone check there resitors and see what you get please?
I'm semi-completly lost... I hate electronic problems.![soapbox](https://rennlist.com/forums/graemlins/soapbox.gif)
Anyone as a used green wire known to be good that you would part with for cheap or just lend it to me to see if it's that. Those baby cost $95.![surrender](https://rennlist.com/forums/graemlins/surrender.gif)
thanks

Ok, replaced the green wire and same thing.
Here is another clue : When I bleep the gas pedal it almost dies!
Electrical? vacuum? AFM? like one suggested....
Remember it was running great before it died while running.

Update :
It looks like my problem is solved.... Nock on simili-wood.
Notice the red piece diconected on the right in pic of post 54!?
Well behind that are prongs wich one goes directly to the FI relay.
This one and this one alone was loose, no other connection on the board was loose.
Deciding to remove the relay board : 7 days
Removing and reinstal the board : 1h
Driving the car : priceless.....
