good evening,

87 s4 manual, had it for a few months. today was the first warm day (65 degrees), so i worked on it, tried to fire it up. no luck.

what i have done so far:
took out the CE panel, cleaned it, installed new relays, new fuses, cleaned it thoroughly.
Cleaned ALL grounds on the car, front to back, including the ground above the CE panel, in the trunk, in the front, in the battery area, replaced gound strap from engine to chassis , etc.... The car lit up like a christmas tree.
The car has been off the road for at least 16 years...

Fuel tank out, cleaned it, replaced the fuel strainer, fresh fuel lines in the back, new fuel pump and filter.
New battery.
INstalled new crank position sensor. was crumbled and the tach was not moving while cranking last month...
Rebuilt LH.
Car cranks, tachometer bounces, fuel pump buzzes. There is fuel at the rail, cracked the nut at the end of rail line, fuel gushed out.
No start. I sprayed carb cleaner, it fires up and idles for a few seconds, then dies.
Spray again and it fires then dies...dont want to over do it, as ether is not the best for combustion...

Fresh engine oil and filter.

Havent taken out the injectors. 

Havent installed a noid light yet. this is how far ive gone on my car.
I have fuel at the rail and i have spark, because it fires on ether/carb cleaner.
So as of now, not sure if the injectors are firing, but i think that is the only reason why the car is not starting...

I will buy noid lights and check this week to see if the injectors are pulsing. 

Any other ideas are welcome.

Thank you,

Sam

i unplugged the temp 2 sensor this morning, just in case. no start. i did not measure the resistance on each spade yet. still having coffee and trying to fire it up.
Ill head to the auto store and buy a set of noid lights today.
I will then peel the boots back on the injectors and try to find a short somewhere....

ok noid light installed, light bulb came on when ignition key turned to on.
Cranked and saw the light bulb pulsate while cranking.


So that leaves me with clogged injectors...
i have spark, i have fuel at the rail, fuel pump bizzes, i have pulse at the injectors, but no squirting im assuming.
It runs on ether, so its starving from fuel... 
Car hasnt run in like 16 years or so. 
Fuel tank refurbished, new Fuel pump, filter, CPS, LH, battery, grounds cleaned, groudn strap replaced, CE panel fresh, new relays... 
DIdnt replace teh Temp 2 sensor. 
Do i still need to do an intake refresh?

I will pull the injectors and clean them and see if that solves the problem.

Thanks,

Sam

pulled the injectors, holes clogged with sand and dirt/. cleaned them and applied 9volts to them, nothing, no life.
Off to look for a set of injectors.
