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

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.

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

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 *** home.

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!
