Please specify your year make and model.

This will help us out, when trying to determine the problem with your 4.3 cpi engine.

On a side note 70 psi is well above what your fuel system should be operating at.

Also you there are tests that you can perform with the proper equipment to check for an injector pulse reference. Normally the injectors won't fire until the dis module sends the reference to the ecm to fire the injector. It could be in the ignition. Most of the problems we have experienced at the shop were simply fuel leaks from the injector spider assm, or a misfire condition.
