Just ship the car to me and I'll fix it right the first time. Shipping costs might be cheaper than just throwing parts at it.

The injection is CIS, so no DME of the later Motronic systems. In the meantime, I've cleaned all the contacts on the usual relay/fuse culprits (well, except for the speed relay under the driver's seat).
No, I'm not sure it's the fuel accumulator. But it's an intermittent, usually warm start problem. If I drive the car and turn the motor off, I won't be able to restart for about 5-10 minutes. Acts like there is some sort of vapor lock. Is the fuel accumulator going? One of the check valves in a fuel pump (as those are supposed to work in concert with the fuel accumulator to positively pressurize the system)? Some odd vacuum leak in the CIS system? My WUR?
I haven't purchased a set of gauges to check fuel & CIS pressures. I've been trying do things in order of least expensive --> most expensive, and/or most common --> less common.
