I would try fuel only that would make things easier to figure out. Email me your MSQ when you get a chance as well. It's also possible that whoever built it messed up your patch harness. It wouldn't be the first time. So make sure that all the pins are in there good and tight and they go to the correct corresponing pin on the opposite connector.

^^^ you know what, i was thinking the same thing. ill pull all the wiring off (ugh) and ill see whats going on with the harness. maybe a wire got loose or messed up in the DB37 connector..? ill check it out.

oh yea, the cranking RPMS never raise above 180 rpm, if that indicates anything.

wiring looks good as it should, i opened up to see if the DB37 harness had any loose wires on my solder job or bridged lines, but everything is nice and snug.

MSQ sent.

Make absolutely certain all of your wiring is set up. I don't know jack **** about the wiring half, so if anything is botched up there nothing I do will help.

ok, well savington came by to take a look (despite that annoying bastard that was cleaning my house the other day..) and we are stumped. we took a look at the settings, and everything was verified as correct.

im completely stumped. I still believe my timing is completely off, does it have to do with my trigger angle settings? should i try adjusting this? im not exactly sure what to do anymore. i plan to email this to DIY and hopefully something can be figured out.

i also took a datalog of the cranking, and hopefully someone can shed some light.

He can't even get the car running let alone checking his timing.

are you still getting the pop on key on? then it's too much fuel. lower the cranking PWs.

im not any more, i think i was getting the pop because i had the coil outputs inverted, and it wouldnt ignite right so it probably flooded the motor.

the other night before savington came by when i was trying to start the car, when the ignition fired, it sounded like air was directly coming out somewhere...
think of it as it sounds like someone is taking an air nozzle attached to an air compressor and presing hte trigger every once in a while. I believe this means that coils are igniting... WHEN THE VALVEs ARE OPEN! wtf. when i tried swapping the output coils AGAIN, i had the same effect, only that it was coming out of the intake brake booster line (when i removed the line from the brake booster to the TB.

well you got spark, you sure you're getting fuel, cause then the next thing is just compression.

i performed a compression check the day after i tried to get it running.
Obviously i cant get accurate readings, because the car is not warmed up.

but i did pull some strange compression numbers

1 = 147
2 = 130
3 = 125
4 = 180

The car was running fine before anything of this happened. i never had an issues with knock or bad running, except with all that bad idle and horrible A/F ratios with being wayyyy too rich (10:1 - 11.4 idle, normal 11-11.5 with slowly running, higher RPMS at 12-13, never got higher than 15 unless coasting) with the emanage.

The car would still run with that much compression. When warmed up it would be much better i'm sure.

I assume you added a CAS to your 99 motor? I'm trying to think of a good way to get timing in the ballpark without the engine running.

What is your trigger angle set to? And where is your CAS set to in its adjustment range? Is it at the retarded end, or the advanced end?

On my car (2000 motor) I'm using a 94 CAS, trigger angle of 68, and my CAS is pretty far toward the retarded end of the range.

When you DO get your car running, and double-check the timing, keep in mind that 10 degrees is with the marks on the crank pulley at 0 and 10 (this always confuses people who are used to the older cars with one mark that you're supposed to line up at 10).

hm, i figured it had to do with the trigger angle. i might have to adjust it, but im afraid of adjusting it in a way where it would ignite before it reached the top... its like a forceful "pre ignition" cause by bad timing i think. any way, how did you determine your trigger angle?

OMG.

Its a miracle.

Long story short...

I change a few settings, bought a timing light hopefully to check some things out. After trying to start for 20 minutes with having problems with the battery crapping out and not wanting to turn the starter, cranking and cranking, IT CAUGHT and fired right up. i checked the timing, was set at 10 already!

YES!

Unfortunately, my car is throwing some CEL codes (i was expecting it) and i had codes P0123 and P0301. Probably P0301 misfire code is due to the stock ECU not hooked up. to the ignition? The P0123 is obviously from the TPS because i cut if off from the stock ECU to wire it up to the MSNS. need to figure out what to do about that.

my car didnt sound like it was running great, sounded like it was kind of running off 3 cylinders, but it gives me a reason to work on the COPs, now that i have figured out the startng issue.

i also had a lot of "water" mixed with black soot coming and dripping out of the tail pipe... i hope thats not to bad. I gotta change the oil after all that starting.

anyway, thanks guys for you help along the way. i appreciate it!
