Ok heres the deal. My buddy fixed a friends truck and now it doesnt run right. He did the headgasket and timing chain. The timing isnt right and we have checked several times to see if he is off a tooth on the cam and it isnt. No matter what we do we cant get the truck to run right unless the timing is set to about 20 degrees. The other side of this is the timing doesnt seem to drop when you jump the connector under the hood. We used a timing light on it to watch to see if it changes when you jump the connector and it does not. My buddy is ready to pull his hair out. Any help is appreciated. The truck is an 89 with the 22 re standard trans. Thanks guys.

 

sounds like the dizzy itself is a tooth off.

 

Unbolt the dist. and see if you can adv. it enough to run. If so, then you are off a tooth. Looking at the rotor, it turns clockwise, FYI

 

The truck runs great the only issue I can see is that the timing is set at about 20 degrees

 

Pull out the dizzy and align the rotor at 12:00. Put the dizzy back in and the rotor should rotate back to around 10 o'clock position (pointing at #1 pulg on the cap). If done right, the bolt with the adjustment should be right in the middle. Then fine tune it from there, there should not be much adjustment either way.

 

Take the valve cover off and turn the crank so that it is at the 0 degree mark on the crank pulley. Check to make sure that the rocker arm on the first cylinder is loose and not stiff. If it is stiff then turn the crank over one time.

Then put your check your distributor by taking it out and aligning the marks on it so that the rotor button is around 12 o'clock. Center the adjustment slot on the distributor to where it bolts onto the engine and you should be perfect. TPS adjustment may be needed if you are not hearing the idle change with the jumper in the diagnostic connection. Good luck!

 

Do you have access to a vacuum gauge?

 

You need to start back at the basics. Turn the crankshaft until it is point to 5 degrees BTDC (NOTE: Pulley at 0 is for the 22R, The 22RE gets set to 5 degrees). When the crankshaft pulley is pointing to the 5 degree mark, remove your valve cover and check that the rocker arm on No1 cylinder is loose. If it is not... then rotate the crank 1 full turn.

Insert your distributor with the slotted opening for the lock down screw centered on the hole where the lock down bolt goes. As you are pushing in the distributor... your goal is to end up with the rotor pointing very close to the 11:00 position. Next ensure that when you put your distributor cap on that the number 1 position on the distributor cap is lined up with the rotor. If it is not, remove the distributor and turn 1 tooth either clockwise or counter clockwise and re-insert. Remember... goal is that no1 position on cap..lines up with rotor.

Next put your timing light on the number 1 plug wire and of course positive and negative on the battery. Start the runner and check the timing. At this point, you should be dam near the 12degree mark. If you are great!!

Next locate the small round yellow diagnostic connector on the driver fender. using a paper clip, fold out the clip into a big "U" shape. Put one end of the clip into 1 slot of the connector. Insert the other end into the other slot of the connector. At this point you should hear the engine rev down.

Check the timing now and it should be at 5 degrees. If you did not set the crank at 5 degrees before you installed the distributor... you will be off on the actual ignition timing.

One key note.... a bad Throttle position sensor is notorious for throwing off base timing. Hope this info helps.
