86.5 D21 VG30i AT 2Wd with 230K was running well.
One day after sitting all day at a job, it started with difficulty.
I remember it not firing and then starting with that kind of sputtering that requires accelerator pumping, like it was a fuel thing. After that, ran well and started without incident for several days.

Then, on the job again and leaving, it started fine, ran fine for a few yards and stopped dead.
Good battery, turned over aggressively.
Towed to mechanic.

Here's what the mechanic reported:

System Check and Advise:
* Check spark- OK
* Check fuel pressure - OK. 36 PSI (spec 36 psi)
* Checked Power to Injectors - OK
* Check fuel injector resistance - both 0.9 OHMS (speck 1.3 to 1.5 OHMS)
* Both injectors are bad. Have shorted windings. Checked for injector pulse with noid light. Each injecotr gets about 3 pulses and no more. Need to diagnose further.
* Suspect bad computer and injectors


I located, purchased and delivered refurbished ECU.

* Unable to prove computer is defective. Not charging out any diagnositics.
* Customer is towing.


I know it's a long shot, but wonder if anyone has shared experience or advise.
