distributor, firing order, timing

[hcr250]

I took out the distributor, im going to replace it but for now i put the same one back in..my truck was running before i took it out, i was going to do my timing, i cant get it, the truck wont start, Ive been working on it so long I forgot the firing order and cant remember which cylinders are what... What is the firing order for a 90 toy dx p/u...3.0 v6...and what is the order of the cylinders on the engine? .....if i have everything right and didnt screw up the wires..what do I do abotu the position of the distributor if my truck still wont start...i shouldnt of taken the whole thing out yet but i did....how do I position the distributor? any help would be good, I need my truck to start by tonight...

By the way, anybody know where to pick up parts for a good price or have any? I need a manual also....

i remembered the firing order and set up the plugs...they are set...I Cannot get the distributor right...the truck will not start...i dont know why im having so much trouble with this, maybe its because its toyotas distributor design with no points...anyway, i set the #1 cylinder, put the rotor at #1, and put the distributor back in, still wont start...can somone please tell me whats going on or tell me what to do....i dont have a timing light, i usually go by ear...i cant find the points of the cam and crank cause everything is so crowded, cant see them...any help would be appreciated...

Ouch, I guess you broke the cardinal sin of not marking it.
The firing order is 123456. 135 are the left bank, front to back, 246 rt bank.
If the timing is messed, you'll have to align the timing mark at 0deg with #1 at TDC on compression stroke. Then install the distrib with the rotor at # 1 position. good luck.

yea i definitly screwed up with that one...its hard to set the crank, no room without removing stuff...

also, how do i know when the rotor is set at #1 cylinder?

If you line up the rotor, or other landmark, to the right spot and then insert the distributor, it usually turns as the helical gears engage and the timing winds up being off. Is this the case with your truck?

Have a drink and think on it. Sometimes a fresh start brings things into focus.
You can do this!

If you know the wires are correct, follow the wire from #1 cyl(there should be an index mark for #1), mark the position on the dist and remove the cap to check the rotor position.
