Toss a set of gauges on the fuel distributor. Need to check running pressure, differential pressure, and residual pressure. There is a way to test the accumulator, but I forget.

I spoke with CIS Flowtech on the phone for a while as my M103 car coughs/misses on cold starts and irritates me. It has good cranking compression 160psi+ and recent full head job. They are pretty sure my FD is leaking down internally, which makes sense. The Ethanol fuel has eaten up one. Doubt my injectors are the issue as the car has not sat for extended times, but could be one.

It fires INSTANTLY cold, then dies. Cranks, need a bit of extra throttle on and off fast (more air to clear flood I figure...), starts, and acts like has a miss. Clears it throat and runs fine. It is related to the EFI, once running car is fine.

Hell, it just made a full power pass at 120mph a few weeks back. Yes, it was closing on redline. I was around 6000rpm sustained. Not bad for 325,000 miles.

You may simply need to tweak the EHA to bump or reduce differential pressure.
