i have a 91 sc300 2jzge

i have a prob with my moter right now just replaced the headgasket got it all zeroed went to start her up and at first really strugled then it fired but ran really ruff as if a miss fire or more then one really bad so i turned it off looked around the moter couldent see anything tryed to start it agen and now it wont turn over like it sounds like it will try or hesitate to and then is just stops also the fumes from the muffler are extremal rich as if it just isint igniting any ideas of how to fix?

my best guess is the distributer is way off?
if this is true how do i fix it?
im open to all suggestions

 

Double check the belt and be sure it's at the correct timing, then reset the distributor. Sounds like the timing is horribly off.

 

the cams and crank i know r right on there marks ima check the distributer in the morning jw if the distributer was just one tooth off wold it be tis bad?

 

1 tooth shouldn't effect it too badly, but good to double check. Did you pull the distributor completely when you changed the head gasket? Might be 180* off...

 

ok i just went out and looked when i poled it out after zeroing the moter cams marks on the cam gears and the first mark on the 0 on the harmonic balancer i poled the distributer the protruding mark on the gear was lined up with the indent mark on the distributer...

and ya i took it out
jw what about horrible spark plugs?

 

If the timing is correctly set I would check to see if you crossed some of the plug wires. Sometimes that would allow a motor to start and run; however, run really rough and may not start at all.

 

ok ill check the wires do u or anyone now what port to what cylinder to make sure. bc on the distributer there are letters on them what order are they and what not?

 

update just triple checked everything its all zeroed i put new plugs in played with timing got it to start and run for a min then when i shut it off agin it wont start still tryin to turn over and it hesitated

 

Maybe you forgot to plug something back in after the head gasket install.

 

We looked it all over cant fined anything out of order so I have no clew now

 

im guessing no check engine light??

 

Did you mark the plug wires to where they go on both the dizzy and on the motOr?

Have you double checked the grounding points? MAF sensor if it's buggered or not?

 

i duble checked wires there all in the right order when i get back to my house ill check the grounds if the grounds are off could that cause the problem?

 

also another thing i remember is when ever i put the key in it makes a really loud buzzing/ grinding sound any ideas what it is and if it may be part of my starting problems????

 

^^^ Saying that it seems that something was connected to a wrong plug of some sort. I'm in Korea at the moment and have been driving two cars, one with a push button switch for fog lamps and air suspension. Whenever I tried to push in the fog lamp switch it'd dim all the interior lamps and make a horrendous buzzing noise... the connectors for both the fogs and suspension were the same but switched around. I say maybe check for any incorrectly plugged connections? Were you doing any work to the car around the dash by any chance?
