help! '91 no start
my 91 6sp has sat in storage for about 5 years and now no start.
had vats issue that is now fixed had 1 Injector out of spec. now replaced.
drained and replaced fuel. It will run with happy juice up her snout. no codes in pcm or ccm. node light flashes during cranking at each injector.
good fuel pressure at the rail. injector ground is at 0.1 ome from ecm connector to battery ground
any body got ideas?

any body got ideas?The next thing I would do is replace all 8 injectors with Bosch III's from Jon at FIC https://secure.fuelinjectorconnectio...il-orings.html. I'd be willing to bet your originals are gummed-up and sealed at the tips. 5 years in storage can cause a LOT of damage. I assume they are original Multecs?

Especially in this case, the OP stated in the first post:
That means that it has spark, and randomly buying ICM's and Coils would be a complete waste of money. That the car runs on ether, shows us that it has spark...problem is lack of fuel.
OP should check his fuel pressure.

Noooo....the CHEAPEST thing you can do is diagnose the problem.

I would pull a few of the spark plugs out and see if they wet or dry.
If dry and the noid light is flashing , then the injector is gummed up and not opening.
I had this issue with 2 injectors.

My 91 had same type issue cranked but no start. Went thru ignition system all new parts, went thru fuel system (new injectors from FIC) still no change, all new sensors still no start. Ended up being a clogged catalytic convertor. Replace with new Y pipe and single high flow cat. Between this and all new ignition/fuel system runs great. Mine had sat for about 3 years in original owners garage, 77,000 miles.
