I have a 89 nissan pulsar with a 1.6 sohc engine. the engine sat in a field for 3 years so i rebuilt it and now the problem is that if i pour gas into the throttle body it starts and runs till that fuel is gone but if i try to start it normally it wont go. I've replaced the fuel pump, fuel pressure regulator and i get fuel from tank to throttle body and from throttle body back to tank but nothing comes through the injector. Wondering if i have a bad injector or a bad throttle body or something else that im overlooking.

Question edited into written English.
Question moved to 1989 Nissan Pulsar (98 or 89?).

It could be many things, usually fuel delivery or sensors. Help in the link

a 35year old car. never seen one me with less than 10 problems.
100% expected. USA car in OK state clearly told and nice!
NO ENGINE TOLD (size) car is called N13 you generation car.
auto tranny and with 4wd?
USA PULSAR NX, IS 1.6L DOHC OR SOHC ENGINE.
ALL ARE INTERFERENCE ENGINES,
NEVER IGNORE THE TIMING BELT . REPLACE IT FIRST.
so is and engine problem, not transmission failure to up shift, correct>? this fact must be learned first. or off base tests go.
engine Power loss has 50 causes. (electric or pure mechanical)
but in basic engine theory (ASE) and gas engines, and otto cycle engines,
the ordered list is.
1: good engine. . EGR not stuck open. CAM BENT NOT BAD OR WORSE SLIPPING. << FAST DRIVING THIS WILL Bring destruction.
2: good spark ,cap, rotor , HV spark wire set and plugs.
when 40mph cliff of failure hits, is engine misfiring? violently?
or is power loss smooth loss of power, RPM fails to rise more. but falls.
the former is spark bad. (ckp ,cmp or caused by cam belt slip)
#3 fueL
if slow smooth power loss,fuel pressure may be low.
if slow gee? the belt on the cam slips. never drive like that.
day one traded to this car, the belt is first ( I just hate bent valves)

The damage is already done. Gasoline breaks down within 1 year. Drain and flush the old fuel out of the gas tank(s). Try adding Chevron Techron fuel injection cleaner to the replacement gas. That may work. However, you probably need to remove all the fuel injectors [if it's a fuel injected engine] and have them sent out to be professionally [ultrasonic] cleaned and tested. Fords are notorious for fuel injector problems. Also do a fuel system pressure test, as the bad gas may have damaged the electric fuel pump [located in the fuel tank(s). For a carbureted engine, you will need to have the carburetor overhauled or replaced with a rebuilt unit. NEVER let a vehicle sit unused for more than 6 months without first treating the gasoline. I always add a fuel stabilization product like Sta-Bil to the fuel, if the engine will not be run for at least 2 months or more. Adding these products after the fuel has gone bad [is already old] will not help. Then it's to late. Below is a link for Sta-Bil. I've used this product for over 20 years. It will save a LOT of grief, when storing vehicles or gas powered lawn equipment. See

Nissan pulsar n13 firing order Nissan Forum

If you are keeping the car forever, swap the engine with a rebuilt one. there are many for sale out there.
about $2k for a rebuilt with core credit. if you are really just keeping it for a year or two until the front "frame" collapses, buy a used engine out of a junkyard, look until you find one with less than 100k on it. there are many for sale on eBay but the shipping will kill you and you most likely have junkyards closer to home.

note if you have an SC1 means SOHC so you have to have a SOHC donor vehicle. SC1,SL1, or SW1
the engines were the same 96, 97,98 i believe. but do not get an older engine.

I hope this helps, it all I could find.

Is it a manual, or an automatic? Earlier Nissans sometimes have a problem with the neutral safety switch (a device that keeps the engine from rolling over in gear or without the clutch depressed.) Generally, if their bad, they need to be a little warm before they'll start, like setting in the sunlight for a few hours.

Good Luck!

There are only two problems but many solutions. Check if there is fire to the plugs. If there is fire check if there is gas going to the cylinder. Once you determine which of these you can address the specific problem.

It might have a damaged valves caused by slipped timing belt making the piston and valves banged each other. That is why the compressions are low. Big job.

1-3-4-2 is the firing order.
