Cold start valve located AFTER fuel distributor. Does mechanic know DeLoreans? Has he jumped RPM relay to rule out electrical problems to pump? Also need to ensure fuse #7 making good contact, especially under road vibrations. Check grounds from pump/inertia switch AND ignition module. Grounding points are a DeLorean Achilles Heel (plastic car). If engine is shutting off randomly problem most likely electrical.

Suspect accumulator or the pump both are less then 1 1/2 years old but the car did sit for about 3 plus months without running any suggestions please help????? Mechanic says it is a fuel problem not electric or relay problem!
