Following your advice posted in previous threads I have done the
following:
1) cleaned claps and installed new battery (it was old anyway).
2) cleaned the engine ground connection behind the dipstick bracket
3) cleaned the ground connection on the firewall just to the side of
the battery.
4) cleaned the positive connection to the power distribution box
There are a few more ground straps though. That about the heat
expanding the connections makes sense. Thanks!

I forgot to mention I removed the relays, cleaned the connections,
moved them around, then decided to replace both the fuel pump and ASD
relays. No change in behavior, but now I have spare relays! Thanks

Re: Delayed start problem
Sounds normal to me, you must give the computer time to run it's
diagnosis. A common reason why the on board error code is not displayed,
people won't wait before starting the on and off sequence.
