1986 Nissan Pickup 4WD 1986 - Answered Questions & Fixed issues

Wow, this open question is pretty old..... Imma gonna take a stab at it anyway.... Try the "check" relay under the hood. It should be located with several other relays under a plastic cover

Never heard of anything called an 'intake coil'. The intake is a tube supplying fuel to the combustion chamber. The spark comes from an ignition coil. https://www.google.com/search?q=1986+Nissan+Pickup+intake+coil ..

It is on the fuel pump under the truck on the passenger side. Right in front of the back tire. You have to remove the metal protective box to see it. Have this truck and most folks answering here have no clue this is a one year issue with this truck.

test blower its self and test that power is getting there (im thinking blower motor resistor)

May be a faulty crank senser

Change the bulb/bulbs on that side. you should always carry a spare set at all times to avoid traffic violations.

Carburetor idle circuit is not working - carb needs to be cleaned and reset to restore normal operation.

This will take too long here. Get some trained help or good home mech. You need to do this safely because of the weight of the trans. You will need an alignment tool to put the clutch back.

The self-diagnostic system identifies malfunctions of signal systems such as sensors, actuators and wire harnesses based on the input signals received by the ECCS control unit. Various malfunctions are coded and displayed on the control unit by a series of blinking red and green lights. Results of the self-diagnosis are retained in the control unit's memory and are displayed when the mode selector, located on the rear of the control unit, Fig. 122, is switched to the On position. When displaying malfunction codes, the code number can be determined by counting the number of light pulses. The red light represents the first digit of the code, while the green light represents the second digit of the code. For example, a Code 32, would be displayed as three flashes of the red light, followed by two flashes of the green light. Malfunction codes can be translated as follows:

1. Code 11 -- Crank angle sensor circuit malfunction.
2. Code 12 -- Air flow meter malfunction.
3. Code 13 -- Water temperature sensor circuit malfunction.
4. Code 21 -- Ignition signal malfunction.
5. Code 23 -- Idle switch circuit malfunction.
6. Code 24 -- Transmission switch and clutch switch circuit malfunction.
7. Code 32 -- Starter signal malfunction.
8. Code 42 -- Throttle sensor circuit malfunction.
9. Code 43 -- Injector circuit malfunction.
10. Code 44 -- All monitored systems satisfactory.

Bad timeing belt, or spark timing system. Last time serviced? Maybe time to take in. let them diagnose.

Check fuel pump.

It is possible that you have a vacuum problem. There could be hundreds of other causes, but start at the beginning and check for a perished rubber vacuum pipe. Vacuum leaks could also occur between the carburetor and the intake manifold, but on a '86 model, just for fun check the play on the butterfly valve shaft. Your car is 28 years old, and the butterfly shaft tends to wear out from years of acceleration and deceleration (throttle valve movement). If you do find excessive play on the butterfly shaft, you probably need to have the carb overhauled, or possibly less expensive, have it replaced.
