19red88quest Posted August 10, 2012 Report Share Posted August 10, 2012 ok so i recently put a new timing chain, gears and all guides ect. had the head freshened up with new vavle job put the motor all back together with new gaskets and it doesnt start. the timing is correct, i have spark, fuel and air. the car will run if your spraying starting fluid into the throttle body with the injectors unplugged. whenever i try to start the car with the injectors plugged in it doesnt fire. i am lost now, i currently have all the nobs on my translator set at zero. if anybody has any ideas or thoughts please chime in i need as much help as possible. thanks Link to comment Share on other sites More sharing options...
Ironside Posted August 11, 2012 Report Share Posted August 11, 2012 Is all your intercooler piping hooked up?Is your tach jumping when you turn it over?Have you tried the stock maft? Link to comment Share on other sites More sharing options...
Indiana Posted August 11, 2012 Report Share Posted August 11, 2012 Your ECU isn't getting the tach signal. The ignition is separate and as long as the timing is close they will run without an ECU even plugged in. The ECU is just the fuel supply. Without a tach signal, the ECU won't fire the injectors. Check the ECI fuse link. Link to comment Share on other sites More sharing options...
19red88quest Posted August 11, 2012 Author Report Share Posted August 11, 2012 the intercooler piping is all hooked up. the tac moves when cranking, unfortunetly i lost my stock maft! i pulled the injector housing and cranked it while my dad watched the injectors, the primary sprays perfect. with that said should i still look for the ecu not getting a tac signal?

Indiana Posted August 11, 2012 Report Share Posted August 11, 2012 If your injectors spray then the ECU has power. You got a compression gauge? Were those hydraulic lifters? Link to comment Share on other sites More sharing options...
19red88quest Posted August 12, 2012 Author Report Share Posted August 12, 2012 yea i checked it before replacing the timing chain. it had 110 psi on all four cylinders. i dont know if the lifters are hydrolic or not the machine shop did all the head work, im pretty sure they are just stock lifters.

Indiana Posted August 13, 2012 Report Share Posted August 13, 2012 (edited) If the rocker assembly was removed from the head then the lifters moved you will have to collapse them. They will not collapse on their own the oil pressure keeps them extended too much and a valve can't seat that's what I asked what lifters you had and if you checked compression AFTER, just before you tried to start it again. I might not have any compression or its too low to run. Check it again. If you have low or none, do this... http://www.b2600turbo.com/lash%20cleaning.pdf Edited August 13, 2012 by Indiana Link to comment Share on other sites More sharing options...
19red88quest Posted August 13, 2012 Author Report Share Posted August 13, 2012 ok that makes sense, i will try collapsing the lifters and see what happens. i checked it before and after both times it was 110. Link to comment Share on other sites More sharing options...
Indiana Posted August 14, 2012 Report Share Posted August 14, 2012 If its 110 now then its fine. You should check the ignition timing while you're trying to start it up and rotate the distributor until you see TDC that will let it start. If its way off like 10ATDC its going to be difficult to start. After it starts up the idle motor may move and after about 15 seconds it will move again then you can at least try and get it to 10btdc but you'll still have to wait until its fully warmed up to set it.

19red88quest Posted August 14, 2012 Author Report Share Posted August 14, 2012 we put a timing light on it while cranking and adjusted the timing a little bit. its really close to 10 degrees before top dead center. Link to comment Share on other sites More sharing options...
Technology Posted August 14, 2012 Report Share Posted August 14, 2012 did you put a spark plug wire on the body, like by the strut tower bolt and watch it spark? Link to comment Share on other sites More sharing options...
19red88quest Posted August 14, 2012 Author Report Share Posted August 14, 2012 yes i checked most main things i could think of. it has good spark, it has fuel and it has air. i havent made it down to my shop to try and collapse the lifters yet but thats what im thinking it is.

19red88quest Posted August 17, 2012 Author Report Share Posted August 17, 2012 ok i went down to my shop today to check out the lifters. im brand new to overhead cam motors so i had a difficult time finding the lifters as my dad did too. do i have to pull the rocker assembly off ? also how would i go about collapsing the lifters? thanks Link to comment Share on other sites More sharing options...
Metric-man Posted August 17, 2012 Report Share Posted August 17, 2012 It's a manual job , but before you do that..... may I ask, .... why you have all the translator settings at zero? Link to comment Share on other sites More sharing options...
19red88quest Posted August 17, 2012 Author Report Share Posted August 17, 2012 i have the translator settings at zero right now so it runs at the stock afr of 10.0. i tried tuning with the translator when the car was running and the numbers were always different like it has a bad mas sensor or translator and at this point im focusing on getting the car to run first. i bought maf translator extensions, could i possibly have them hooked up wrong causing it not to run?

Or like you mention it may need attention anyway. Edited August 17, 2012 by Metric-man Link to comment Share on other sites More sharing options...
19red88quest Posted August 18, 2012 Author Report Share Posted August 18, 2012 im running a gm mas air sensor. i will try adjusting the idle settings, but i completely forgot how to work the translator. i remember that the aux doesnt get used and then theirs 4 dials on the bottom which is which and which way is leaner and richer?

Metric-man Posted August 18, 2012 Report Share Posted August 18, 2012 (edited) If you have this dial type I would think it is self explanatory. Why don't you look at this PDF and see if you can figure the dials out? http://www.fullthrottletech.com/attachment.php?attachmentid=37&d=1093665074 Here is a link to the settings thread.. http://www.starquestclub.com/forum/index.php?showtopic=107897 http://i636.photobucket.com/albums/uu89/daniels_zx6/2010-05-20104201.jpg Edited August 18, 2012 by Metric-man Link to comment Share on other sites More sharing options...
19red88quest Posted August 19, 2012 Author Report Share Posted August 19, 2012 ok i figured it out thanks. i tried messing with the idle settings and nothing, just cranking and cranking. so monday im gonna bleed the lifters and see what happens.

Shelby Posted August 21, 2012 Report Share Posted August 21, 2012 if the injs have been spraying fuel all this time the spark plugs are drown'd , try a new set of plugs Link to comment Share on other sites More sharing options...
19red88quest Posted August 21, 2012 Author Report Share Posted August 21, 2012 ive been checking plugs, their dry like the vavles arent opening properly to let fuel in the motor. thats why the intake gets 1/4in of gas in it. Link to comment Share on other sites More sharing options...
Indiana Posted August 21, 2012 Report Share Posted August 21, 2012 Take the plugs all out of it, check compression again. Take your finger and poke it in the #1 spark plug hole and turn the motor over by hand and when you feel pressure building stop turn it. Now continue turning clockwise until the crank pulley mark lines up with the TDC mark on the timing cover. Take your dist. cap off and make sure the rotor tip is pointing like the picture I posted. Stick a screwdriver in the plug wire and lay it across the valve cover and crank the motor over and watch for a spark. Take the pipe off leading into the throttlebody and look inside and make sure fuel squirts as the motor turns over. If all that is happening, you put the plugs back in it will run.
