SOURCE: I have a 1986 Nissan Pickup D21 that bogs down

your carberator is gummed up. Go to the auto parts store and get a can of seafoam fuel additive. Read the label so you get enough but as I recall you put in one ounce per gallon of gas. Run that through your pickup for a few miles and it will purr again.

On a 1990 Nissan axxess it starts up then it shuts up and struggle to turn back on what could be the problem.

This could be anything from bad spark plugs, wires, rotor, and distributer. It could be fuel delivery, or bad gas. I would start with simple things, change the gas filter, the spark plugs, take a look at the distributer cap and rotor and the spark plug wires. If it has been sitting for a long time, pump the tank out and put fresh gas in.

Replace the Distributer Cap, rotor and pickup, this is likely the problem rather than wires, and not hard to do.

Ihave a 1987 nissan pickup Ihave spark from the coil but not to the plug why

If you have spark on the high tension lead from the coil tower, then there must be a problem with the distributor cap or rotor. The cap may be cracked. Look for black fine lines on the cap. The rotor button may be worn, and not making contact, or the rotor arm may be worn. New cap and rotor!
Your spark plug wires, are they still good? Still supple (not brittle or cracked)? You can check them with an ohmmeter to see if the resistance is still within acceptable range.
Good luck.

My 1990 chevy pickup just stopped running.

there should be 2 clips on from the rotor housing to the cap, pull the clips off and lift the cap, you will want to change the rotor inside as well. do not remove the spark plug wires from the old cap yet...replace the rotor, it will only go on one way, and put new cap on, it too should only go one way. now, one at a time, pull the plug wires and put them on the new cap that is mounted. this will ensure that you have them in the right order.

1990 nissan sentra wont start

It seems you have a timing problem. Have the engine timed properly. If that does not work it could be a craked rotor or distributor cap. have all these checked.
