Top 10 1994 Nissan Pickup Questions & Answers

I would start by checking the resistance of all of the injectors. I saw this happen last week, I had a new injector that was reading low ohms and it was making two cylinders misfire. Replace the new one with a another new one and both cylinder ran good. I dont know what the ohm value of your injectors should be but I would want at least 10 ohms, All of them will be about the same except the bad one..I did a web search on your problem and it was covered at several places.

its mounted on the right fender well

I would venture to guess that a timing chain guide broke and the chain chewed a hole thought the timing cover. The timing cover also has coolant passing through it where the water pump is attached. If you were running a multi viscosity oil, even it it were a 20-40 and got surprised by a zero degree day, I doubt seriously, it would cause that to occur. That series engine had problem s with timing chain guide failures. However, there usually is some chain rattle well before a disastrous failure. Most of my customers noticed the chain noise before it has caused catastrophic damage.
Sorry you have suffered such a loss. Good luck on your repair. A used timing cover would be the cheapest route. A place in Dallas called Bishops, buys engine cores, dismantles them, evaluates them, cleans the good parts up and sells them at very reasonable prices. They ship all over the country.

Hope helps (remember to rate and comment this).

This problem is caused by a defective brake light switch, the switch is either out of adjustment (it is a threaded adjustment) or is defective, it is located under the dash and at the top of the arm the brake pedal is attached to. There will most likely be a plastic panel under the dash you will need to remove to see the switch. Here is a picture of the brake light switch.

Yes the AC compressor swich could be bad, you could check switch continuity possible bad contacts. Also check to make shore you have proper DC voltage supplying switch, should be 12 volt DC.

Clean the battery post's and terminals and hot wires to starter and the ends of the ground wires. Try to jump start it if it starts it may be your battery or your starter is going bad.

Check the cable that connects the Gas pedal to the throttle plate in the intake manifold. Cable could be streched or breaking and not opening the throttle plate all the way.. another easy thing to look at is just past your air filter is the Mass Air meter.. open it up (take the large hose off) and clean it. there is special cleaner for this job.. its a spray available in any auto parts store. You replaced the CAT.. is there any other possible blockage in the exhust system.. this is a classic symptom of a blocked exhaust. To check this you would unbolt the front part of the cat and run with a open exhauset just to see if it corrects problem. Very loud but a last ditch choice. Check air filter?? I have seen rats nests in airfilters in the winter.. this usually causes the engine to smoke from too rich mixturee.. but the fuel inj systems are so smart now they might adapt to a blocked air filter and reduce the amount of fuel.= going slow.
