Ok, and you did try a different solenoid resistor and still nothing ?. Im running out of ideas, your 4Runner is doing the same thing mine did when it wouldn`t start, i had fuel and spark and tryed everything i could think of, and just for the hell of it i tryed the spare solenoid resistor i had and it started. When you try and start your truck can you hear the fuel pump running ?, if not then jump it at the test conector under the hood. have you checked the fuses behind the kick panel on the driver side, check the ignition fuse and efi fuse, make sure there good and not coroded. Do you have power to the dash lights and everything else ?.

well i unpluged the hose going to the fuel rail and gas does come out when i turn the key on.....and its getting spark...and its getting gas to the spark plugs....so im sure it works... and ive checked every fuse 3 times....i know im running out of ideas my self... know let me ask u i something is wrong with like the igniton controll module or coil will it still spark?

854runner4x4

and the thing is it ran right before i pulled it out then after it just dint.....

myyota

If the ignitor or the coil go bad you won`t get any spark, why did you pull the engine, did you just rebuild it ?, did you replace the timming chain ?, if so did you get the timming maks lined up properly ?. Another thing to check is the distributor, make sure its not 180 degrees out of time.

854runner4x4

yah i did the chain right....i took the cover off 3 times to check it....and as far as the distributer goes i had 180 degrees off and it was backfiring when it was just turning over so i changed it 180degress so as far as that goes i believe its right too?

myyota

If its back firing while your trying to start it, then it has to be something to do with the timming, go back and check everything again. It sounds like it wants to start but can`t because something is off (out of time).

854runner4x4

yah..hey whats the piston order from front to back is it 1234 or 4321

myyota

Front to back as far as i know, 1234.

myyota

The firing order is 1342

854runner4x4

yah i know that..but i was just seeing the other part man im gonna have to take the timming cover off one more time and check the chain again...

myyota

That sucks, but its got to be something in the timming, im sure were on the right track.
Let me know what you find.

854runner4x4

ok now i have no compresion on in cylinder number 3 and its bearly any......and how exactly is the timming chain supposed to be set cuz mine is a single chain..and theres only two discolor links in the middle of the chain like one on top and one on botom..... how exactly does it go...cuz my book tells me how to do it with the double chain

myyota

If you have no compresion in #3 then that a big problem right there. The colored links on the timming chain don`t mean anything as far as i know. There is a timming mark on the cam gear and on the crank gear, they need to line up with each other on the intake stroke. If you have the chain installed and the crank and cam are out of time then that can cause the piston to hit the valves and cause major damage. So if you don`t have any compresion in #3 cylinder, its possible that - that is what happened.

leftovers

run a compression test i bought a 79 with a 20r lots of spark lots of fuel no compression cranked like a champ(no resistance lol) should run about 156 to 160 psi mine was 0 to 50psi!

854runner4x4

no number 3 is the only one with compression and its like 30

myyota

If number 3 is the only one with compresion and very little at that, then your motor is toast, you either need a new one or you need to have the one you have rebuilt. How many miles are one the engine ?.

854runner4x4

the engine was rebult 40,000 miles ago...and it ran before i took it apart

myyota

But if you have no compression in any of the cylinders then something major has happened to the engine, and like i said before, if you put the timming chain on wrong and the pistons came up and hit the valves then you have major problems. You need to pull the head and check for valve and piston damage.

yah ama take it off tommoro morning

myyota

Let me know what you find.
