'88 RR 3.5 EFI - need to upgrade EFI system

Blocked injectors perhaps??? fuel rails rust out and crap either catches under the regulator holding it open resulting in low fuel pressure and/or blocks the filter cups in the injectors. Had both of these happen at the same time on the 3.9............

Hi guys

many thanks for all the valuable info - lots to follow up!!

PhilipA - Just driving along - engine coughed, then just died - just a few minutes after being at rest all day - a few stutters before the battery died.
NRMA called to 1. check for loose wires etc, then to 2. organise a 'lift' home.
Obviously something has failed - either a loose wire or a malfunctioning circuit board - checked all wires, now to keep replacing boards!!

thanks all!

If it just cut out , that may be your problem.
