I've got spark, fuel, compression--yet no start.

I'm out of ideas. Can someone point me in the right direction? I must've missed something.

 

How old is the fuel? I had a vehicle in my shop last week with the same symptoms and it had bad fuel. Started and ran perfect after draining and refueling. Is the fuel checks out, and you have air, fuel, and spark, the only thing that would be missing is correct event timing for all three.

 

The timing is good, but Im not sure about the fuel.
It's been sitting since October. How long does it take for fuel to go stale?

 

It's hard to say but all of the crap they put in fuel nowadays can't be a good thing. Also remember that they add even more crap to fuel in the winter months, and last October would definitely fall into that bracket. How much fuel is in the tank? It's a pretty easy task to drain and refill, could help more than you would think.

 

Have you tried the deflooding procedure?
all that cranking could possibly flood it

 

Put some automatic transmission fluid in the lower spark plug holes and see if that doesn't do the trick.

Well, I drained the tank. Then put some new gas in it..same results.

Do you know how to test to see if the i njectors are firing?

 

is there fuel on plugs?
how did you test for spark? simply grounding the plug in open atmosphere isn't enough. you need to HEI test the ignition system. the tester places resistance on the system comparable to live operation. they're cheap. maybe 20$. and easy to use. worth its weight forfuture use as well

 

the only way to actually test if the injectors are firing is by way of a noid light. you insert a 194 marker bulb with its tangs peeled back into the injector connector. then you watch the bulb flash while someone cranks. this only checks for pulse at the injector, and not the injector itself. however, seeing as how your car is a t2, accessing the injector sockets is not something you want to get into at this point.
if you've got fuel on the spark plugs, we will assume they're firing.
you should probably check your fuel pressure

 

an easier way of checking the injectors is if you have a spare CAS, hook it up and spin it with the key on. you will hear the injectors clicking over while spinning it, if you get nothing then they aren't working.

if the injectors aren't ticking over then the usual cause is a bad ground on the rear rotor housing on top of the engine.

 

^^that's a cool method. going right in the memory bank

 

I don't have a spare cas, but I did check the ground on the rear rotor. I cleaned it up, but still no start.

Is there another way to check those injectors?

 

I tested each of the primary injectors with a test light--probe in one connector and the ground in the other. Had someone crank, and the light blinks, so it's getting signal. I also pulled the fuel line off the lower rail and cranked, it sends fuel.

 

You could try pulling em out and running a system like in this video
