Subject:fuel pump relay problems?!!!

Thanks to all that sent me their advice on my relay problem.  I just have some
more info.

1) Both of the relays in the Eng. comp are the same is this normal? mine are
they are a relay 40 amp w/ a resistor (I opened it) looks OK as a relay should
2) Before this thing went bad when you turned on the key the pump would run
for 2-4 sec. I guess to build up pressure. Now it won't shut off.
3) I disconnected the pump wires at the pump and the relay stopped chattering.
4) I checked and wire brushed the 2 ground posts under the coil.
5) What happens if the idle control unit is disconnected will it still start?
Disconnecting mine made no difference in my problem.
6) I checked the large grounding strap =2 ohms.
7) I disconnected one by one the afm, temp mod, throttle sens, p/s sens, oxy
sens, dist, just about everything I could find in the Bentley.

The relay still chatters, it wont start, and the injectors are firing at
random. The tach is at 0 mostly but sometime it jumps to 1000 then falls back.

maybe it will fix itself (yeah right)

thanks to all
Kurt Thomas
