ok so im pretty stumped on this here is a video i made, i thought maybe i was off a tooth on the cam but it looks right to me what about you guys?

Kiroshu

Still no start..?

I assumed you verified and correcting timing chain timing marks.

The Camshaft sprocket in your video is dead on.

Does the Rotor button point to #1 cyldiner on the distributor cap exactly..?

If not reposition distributor drive gear until it does so.

mc360

sorry about the video idk why it uploaded upside down. it starts but where i have the distributor now it had to be fully advanced to start (with gas pedal being pushed) and the timing light shows it at like 15 degrees btdc. if i pull the distributor and rotate the rotor either clockwise or ccw it wont start with the housing fully advanced or retarded

Kiroshu

Engine at TDC #1 cyldiner. Distributor rotor button should be pointing at #1 cylinder on the distributor cap.

mc360

when i pull the distributor off and move it a tooth forward or backwards it to far either way to where it wont start

Kiroshu

mc360

this is where it is at

Kiroshu

Is the crank shaft at TDC along with the camshaft...?

Crankshaft at TDC #1 cyldiner.

"Notch" on crank pulley/vibration damper pointing at 0*...?

Cam and crank must match TDC together or the engine will not operate properly.

It seems like your distributor is still installed incorrectly to the engine being at true TDC.

Seems like you have the distributor installed at TDC for the camshaft when the crank shaft is not at TDC. (Which I believe would be #1 cyl's exhaust stroke.)

Line them up together and re-install distributor.

mc360

The video shows the crank at 0 on the timing mark and you said the cam was dead on

Kiroshu

Oh missed that part in the video ^_^ I see it now though.

mc360

So what is your guess, it wont idle since i changed the timing chain and i had to advance the distributor so much that it pings under load

Kiroshu

Stopping the video at 0:11 shows the camshaft on #1 cyldiner on the exhaust stroke.

You can see the lobe lifting up the rocker arm opening the exhaust valve.

Kiroshu

Actually.

I wonder if I can zoom in the video. I think its ok as far as that.

Kiroshu

Yea never mind I zoomed in on it. For second I swore the lobe was pointing up on the camshaft.

Kiroshu

Very interesting. The way you describe it.. it sounds heavily like the distributor timing.

Kiroshu

May not be a timing problem at this point. Seems everything is in order.

You received the truck with it not running correct...?

Possibly restricted exhaust system..?

Compression...?

Vacuum gauge..? (Verify internal engine health.)

Spark plug gap..?

mc360

I bought the 4runner running but knowing it needed a timing chain, i just replaced the cap rotor plug wires and plugs with ngk Bpr5ey (assume they are oem so i bought some new ones) the gap is what ever those plugs come with stock.

I dont know the compression since i dont have a compression tester vacuum gauge or air compressor

Kiroshu

Ignition Cables(Wires) Distributor cap installed correctly...?

mc360

Yes i pulled one wire off at a time and replaced it before i moved to the next, but i will recheck
