1992 Nissan Pickup - Answered Questions & Fixed issues

Buy the chilton manual and some tooling that's a start

The craziest thing happened to a sunbird I once had it had electronic Speedometer. The speedometer would show anywhere from 20 to 30 MPH sitting still. I will always remember it because it turned out to be a bad voltage regulator. I had to change the alternator. It could be other things but it should be cheep to have your alternator checked. Most Auto supply places will check for free. My car did not do it till you drove it around a while. If you can have it checked after it starts acting up I think it would be a better test. Just a thought which came from my past.

Check your clutch pedal switch,may be loose or bad,I have a 85 nissan 720,replaced my switch their years ago.

That compression is pretty low, you should be seeing around 140+ per cylinder. I would try a squirt of 90 weight in each hole and see if it will start.

Did you inspect and clean the connection fitting? You should also use a bulb connector fitting lubricant...did you touch the new bulb with finger grease or any dirt? These headlight bulbs are extremely sensitive to hand oil...the connection sounds serviceable...Hope this helps.

Timing marks are off. Get access to the crank mark and cam marks. Make sure they are in the right position. Reset them , turn the crank two revolutions by hand and make sure they are still lined up. Not close, but lined up. If off a bit, use a pry bar on the tensioner, tighten up and recheck.

all PCV valves are located in valve cover

I can't remember if the j21 has a single or twin cams, but here is a solution if you haven't taken the old timing chain off yet. Take off the timing cover and the camshaft cover. Remove all spark plugs. Place a wire (welding rod or a piece of an old wire coat hanger) into the n;umber one plug hole - this is the plug for no. 1 cylinder, the cylinder nearest the radiator. Turn the engine until the exhaust valve just closes and the intake valve just opens. This is referred to as the valves "rocking". At this point the wire should be right at the top of the piston stroke, and the number one piston is timed to take in gas on the down stroke, that is, the intake stroke. At this point you should see the timing marks on the timing gears and their relationship to one another. The marks are either dots on the gear teeth, or marks on the camshaft which line up with marks on the cylinder head. These marks line up when the crankshaft is at top dead center, which is the position you turned the crank to while feeling the position of the piston with the wire. I wish you well, good luck.

If it has a carburetor you probably need change the float and needle and seat.go to utube and look

you will have to check fuel pressure and volume. can you hear the pump run, when was the fuel filter last changed. are the injectors working.

Could be anything. Vacuum, valves, rings, tune up. Check vacuum lines. Then check compression before you do a tune up. If you have bad compression in a cylinder, tuneups don't help. In that case, either drive it till it dies or replace/rebuild the engine.

Are all 4 of your tires the same size?

they must be there once oppened

It sounds like you have an exhaust obstruction. Check that you have good exhaust flow out of the tailpipe while the car is running. If you do not have good flow out of the tailpipe, begin trying to find the clog. (You will likely find that the "breakdown" ruined the catalytic converter and clogged it.)

Check the slave cylinder for leak, 9/10 times is the slave cylinder. Check for fluid on the filler cap.
