? some help ? timing ?

hey ,
whats up all, i cant seem to get my maxima running, i just finished putting my engine back together and the only thing thats off is the timing. im getting fuel and spark, just no firing. i have my full stand alone all wired up, it is working fine, but now i cant get it to fire at the right time. atleast thats what i think is the problem. i've tried everything i know what to do.

any sugestions or help

how do i know if i set the timing right?




anyone ? oh, come on!

Do you have spark? Take a pulg off set it on a ground, and double check you do.

if you dont have a timing light borrow or buy one.


Find TDC of cyl #1 on the compression stroke. You probably need 2 ppl. 1 to turn the key and bump the starter or turn the acc drive pully, and the other to hold thier finger over #1 plug hole to see when TDC passes.

What me and a friend did is turn his acc drive pully, while I held my finger over the #1 spark plug hole. He rotated the crank shaft the normal way untill I felt the cyl push air, then try to suck it back in. Then I had him stay at that position, turning back and forth a little to find TDC. Then we went 10deg backwards (15 deg for the max) before TDC. Then we put the dis at #1, as if it was firing.

what that did was get us on the #1 cyl's compression stroke ~15deg BTDC which is exactly when the plug should be firing. Now thats done use a timing gun to check the timing.

Pretty hard to diagnose when you mentioned you put in a full standalone ecu. I mean that in itself could be a source of 5-19 potential things

i did that, and no start i've tried like everything



the ecu should be running correctly, it has everything else working right.
will holding the key down for like 7 - 11 seconds be bad? like just let it keep trying to start?

if the timing is off will there be a little bit of smoke coming out of the valve cover when the timing is OFF.

oh BTW this a motor that hasent ever been run before, i turned the motor by hand to try and get oil threw the motor. then i turned the key for like 2 or 3 rotations, like 2 seconds, and then let off.

slide a long screwdriver or a wood dowel in the #1 spark plug hole.

turn the crank..BY HAND and watch the screwdriver dip down and then go up. once you determine the full up position you're at TDC.

now take your distributor...clock it slightly before the #1 cyl position...(match it up on the dist cap peg if you must) and slide the dist in. when you slide the dist in it will want to turn. you might end up past the #1 peg that you had it at. if that's the case pull it back out and back it up one cog/spline/tooth on the gear back so your dist will install in and you're slightly before #1 peg.

go back in the car and try to start it. if it doesn't start it would sound like you're "close" to starting but it's not catching. that's good..you're close. you might also see some smoke and smell gas. you can try turning the dist and making the adjustment...keep the dist bolt semi loose.

if it still doesn't catch repeat the above but move the rotor farther back (before the #1 peg) another tooth and try again. if you don't see smoke at all or almost starting then your standalone is not wired/set up correctly.

i'm going to over look post #3 because you're a total a-hole for posting that because YOU need help...not us...but from the years of you being on the forum i almost expect it from you.

another reason why i don't post all that much now.

good luck

Are you sure the injector timing is correct, if the ignition timing is? I'm not familiar with your engine, but it must use a cam timing sensor or crank angle sensor to fire the injectors. Is that oriented correctly? Perhaps the injectors are squirting out of cycle.

what standalone system are you running? Haltec? Megasquirt? you need to give us more info.

i have a megasquirt, how do you check to see if the injector timing is off?
my friend has a megasquirt in his elcipse, and it runs fine. he tunned his and is helping me tune mine.
we tried starting the engine for about only 20 mins, and then gave in after a long night.

would just cranking the motor do any good?

i did the whole find TDC, and put the rotor on cyclder one, and it didnt start.
i tried messing with the degrees of the timing, with my megasquirt and with the distributor, but no luck. im going to be messing with it tonight and trying to get everything situated, i have to go over some little things and double check everything, but ill find out.
thanks for the help

oh danny, ur the best moderator on here <3
if u lived close to me, i'd have yea come over for a beer
all the things u said happened, i did the rotor thing, and smoke did come out of the valver cover, and i did try adjusting it. all i know now is that i have to fix a little problem i have encountered, my fuel rail is leaking a little,
now if there is some coming out of the valve cover, and it really sounds like it wants to start, should i just keep cranking it? or stop and try again.?


DANNY = THE BEST <3
