fuel + timing + compression + spark = a not running engine
 

Ok, i made a post yesterday about this and i couldn't find it so i figured id just make a new one with the new information i've gathered.

I have fuel going in to the cylinders and i checked injector pulse on cyl #2 and there was one.
I have good compression
My timing is at about 15* btdc using static timing
The car cranks quickly because it is hooked up to a battery pack
I have spark all the way at the plug at least on cyl 1 and 3

so let see. fuel, timing, compression, spark = a not running engine

it doesn't even catch at all. just cranks.

This is all after just replacing a headgasket because i blew my other one.

im sitting in auto and i can't get a ride home for at least an hour and a half.

This is a 93 240sx ka24de. HELP!

*edit* just saw that my other thread got moved and thats why i couldnt find it. Sorry mods

Checked all fuses and plugs (MAF etc)?

Re: Need Help ASAP!!! I need my car to run NOW
 

So you didn't check for spark at your other 2 plugs?

Re: Need Help ASAP!!! I need my car to run NOW
 

codes?

Re: Need Help ASAP!!! I need my car to run NOW
 

maf

it would at least try to start if the #1 cyl is good. you'd hear the first one pop and then that would be it.

Re: Need Help ASAP!!! I need my car to run NOW
 

Fuses would be a good start... Codes as well. for some reason I didn't check those.

my car does run with the maf unhooked.. i've tried it before. it runs poorly but it does run.

I know i should check all plugs for spark. I definitley would if the engine caught at all, but right now i don't any pops or anything. just ------- cranking

Re: Need Help ASAP!!! I need my car to run NOW
 

Un hook the MAF and try. My boys suby did that after driving threw a puddle and shorting it out. as soon as we ditched it it fired right up. Of course it was suiside taking it past like 3 or 4 grand but it will get your ass home.

Re: Need Help ASAP!!! I need my car to run NOW
 

ok, tried it without the maf hooked up

fuses are all good

ecu had a crank position sensor cel.. put in a new distributor and no problems were solved.

any other ideas? I'm ---- out of ideas!

*half bump, half comment*

If my lower timing chain was off a link, could that cause this?

Re: fuel + timing + compression + spark = a not running engine
 

and this one is also in general why .. ?
*MOVED*

how do you know compression is good?

Re: fuel + timing + compression + spark = a not running engine
 

checked compression with a compression checker.

if one of the timing links was off would there be the correct compression?

Re: fuel + timing + compression + spark = a not running engine
 

up up

i think the bottom chain might be off a link. would i still have compression? If itwas off a link could i just compensate by moving both cams one link left or right? I really really don't want to pull the front cover.

i got the same prob but mine is a 91 teg ls

Re: fuel + timing + compression + spark = a not running engine
 

Im in the same boat with a fully built H22A 9:1 Ross pistons. I have fuel sitting in my runners and it runs for no more than 30 sec, then dies and I dont have alot of vac at the TB when I put my hand over it. ANYONE KNOW? if piston 1 is at TDC and the markings on skunk2 cams are set facing up and in the center of the cam caps,,,,,,is the correct timing minus the dizzy's fine tuning.
