Default 94 GSR Wont Start

Trying to start my 94 gsr, but it only cranks and doesn't fire what-so-ever. So far I have checked spark at all 4 plugs, that is OK. I have fuel pressure when I remove the return line and crank it. The plugs smell of fuel, but are not wet. There no CEL codes... The firing order is correct and I believe the timing is OK. Any ideas of what to check?

Ignitor? Coil? Sounds like you have spark for no FIRE!!!

Spark is bright white/blue on the plugs... Is there a chance my timing could be so far out that it doesn't even sputter?

Possibly but not likely. At the worse timing adjustment the car would still start and run, it would just run like pure shit.

I forgot to add you may want to start looking in to modulator within the distributor if that is not working the car will not start.

I forgot to add that it's a new starter and the engine is turning over. Accessory belts are turning and the distributor is spinning off the cam.

if you are seeing a spark the problem is almost certainly not electrical. how exactly are you checking fuel pressure?

Checked fuel pressure by removing return line and cranking the car over. Squirts like a mofo.

So I am so desperate I pulled the whole fuel rail off with injectors in it. When I crank it all 4 injectors fire pulses at the same time. Not sure if that is correct or not... Also, I pulled the valve cover off to compare the cam gear position at TDC to the distributor and piston position at tdc and it all looks ok... I am stumped.

yeah it sounds like you've pretty well confirmed fuel and spark so that leaves compression and timing. whats the background on this, did it run fine and randomly quit or is something you were already messing around with?
