I have spark [bright white].
I have fuel [~39 psi].
Threw codes 11 and 21.
Crank angle sensor fine [injectors click every 90 degrees hen spinning the shaft].
Ignitor fine [checked resistance between pins].
I put a highport cam in it, an adjustable fuel pressure regulator, and a header.
Cam timing is right [ at 0 degrees exhaust cam sprocket dot is at 12o'clock with 20 pins between cam sprocket dots].
Ive swapped the MAF, disto, ignitor, coil and took off the MSD ignition.
Cranks but thats it, not even a hint of firing.
In the fsm it says if showing codes 11 and 21 to check things that would cause a bad crank angle sensor. What would that be? The cam timing is right.
I am completely stumped. Pretty frustrated also. I can usually nab problems fairly quick, but I have no clue.
Please, help me out. Im hoping thats Im just over looking something obvious
Im thinking it has to be a timing issue, because of the fuel and spark. I also tried rotating the distro cap while someone cranked it, no hint of firing.
Its my birthday, so pity me and my POS SE-R. If someone can figure this out I'll send you a free sr20forum.com decal or a bunch of them, I dont care. Just help me!
The crank angle sensor is housed within the distributor. Try another dizzy. Thing is though, if your CAS is bad, you probably aren't getting any fuel. If the CAS isn't working properly, I don't believe your fuel pump will operate.

Check the power transistor. When my brother first got his engine in, we couldn't figure out why it wouldn't fire, but it just ended up being the power transistor.
Yea the CAS is fine, as is the ignitor(power transistor). As for the distro being 180 out, mine can't go 180 out. The slot in the cam is slightly offset. Keep the ideas coming though... Thanks guys!

Trust me Nick, its possible! I wouldn't have believed it myself until I accidentally did it.
well before I tried putting the distro in 180 out and I couldn't. turns out i had the cams 180 out but that is fixed now. I tried for about a half hour to get the distro in backwards (because the cam was backwards) and no go. im almost positive its bot the distro but ill check again. no harm in double checking
If your crank signal was bad you should have no spark. You sure you are getting fuel to the cylinder? If you are getting spark and fuel it should at least try to fire. Where are you checking for spark at? I think you have a bad crank sensor.

if you pull the disto out and turn the shaft every 90 degrees you can hear an injector click and the fuel pump run. unless im mistaken, this would mean the CAS is fine.
Checking for spark I connect a wire to a plug and hold the plug to a ground and it sparks. The only thing I can think of is spark is out of time.
This thing has be completely baffled.
Im also starting to lean towards a bad ECU. the only thing I can think is I damaged it when taking I out of the bracket to check codes before I realize cam timing was off. Unrelated, but I thought it was odd that the LED and screw were on the side facing the fire wall.
No, they come out wet. I havent had a chance to touch it, but hen thinking about it Im thinking it isnt sparking as much as it should. What I mean is, it isnt sparking ever cycle. Im thinking coil. I have a MSD Blaster coil, and I swapped it out for a stock coil I had laying around, but I can't remember what that coil came out of, and if it is good.
So tomorrow... swap out with the coil from my running G20. After that... ECU.
But that would force the cam timing to be off at TDC. He said it was dead-on, so timing isn't going to be the issue. Unless, of course, he didn't check it at TDC.
when you turn the key on do you have a check engine light? if so more than likely the ecm is good. if your sure you have fuel n spark, dbl check plug wires coming off cap are going to the right cyl. when i go to the shop tomorrow ill pull up the trouble shooting ish for those...

With the crank at TDC, the exhaust cam sprocket's dot is at 12 o'clock, with 20pins to the intake cam.
I still havent got a chance to touch the car. Two full-time jobs, and 3 broken cars don't leave me with much free time. It is at my parents house, so I can only work during the day.... Tomorrow morning maybe....
