Hello Nissan Hardbody Brothers and Sisters,

I have a '89 Nissan Hardbody (1 owner) me.

I've severely mistreated my bestie. She's been by my side longer than any human relationship I've had.

I've let her sit in my back yard until code enforcement threaten me with a $200 fine.

Yes, she is very sentimental to me my Grandfather bought me this ole girl for me.

I get offers all the time for purchase. I finally started tinkering with her and did a major tune up with no start.

I did alot of research recently and the bug to fix her has hit me. I can't hear that annoying hisssing when you turn the key........ So google that hissing and that is the fuel pump! So i unhooked the fuel filter and no gas is coming out.

So I was very scared of dropping the gas tank or removing the bed. Well i got an itch and jacked up the truck and dropped the tank to look at the fuel pump.

needless to say the fuel pump, assembly and gas tank is completely rusted out. I've ordered those items and will let you guys know what happens.

p.s. i'm shame this truck has been sitting up for more than 10 years

Waited 9 years to make your first post since joining!
That's amazing!
Good luck getting it running again!

Wow man that's pretty brutal. Go ahead and inspect the fuel lines, and budget for a new fuel filter. Pray it didn't make it up into the injectors, or you'll have to replace those too. I'd recommend purging the fuel lines before you try and start it again.

And +1 for having your first post 9 years after joining. Way to open with a bang. Can't wait to see more

LOL, Well I joined this site for another reason (2001 Infiniti I30) That was my girl too, I gave her to my daughter and i bet yall can't guess what happened to that car....

PapaSmurf2k3 Thanks for the advice.

RIP I30 haha.

I'm having trouble find youtube on flushing the fuel system. If anyone has instructions let me know ASAP. LOL

Post by **velkin** » Sun Jul 10, 2022 9:39 pm

I saw where a guy ran a $12 generic fuel pump, with an external fuel cell in the bed of his hb, and he ran a jumpbox instead of a battery. Dang! I need to go to sleep.

I'd start by disconnecting the line after the fuel filter, before the injectors. With the lines by the tank/pump disconnected, you should be able to hook some compressed air to one side or the other and "blow" the lines out.
Then, once your new tank and fuel pump are in, put some fresh fuel in there. Leave the line disconnected after the fuel filter and cycle the pump a few times. Replace fuel filter and cycle pump again. Hook the line back up to the injectors and hope your fuel filter doesn't clog again.

Thanks I'll let everyone know what happens in about 10 years. Lol!

Okay new fuel pump hoses and tank progress.

I'm flushing fp lines today.

It didn't take me 10 years!

This pleases me. Welcome aboard, I love my little D21!

Post by **PapaSmurf2k3** » Mon Jul 18, 2022 8:47 am

Outstanding!

Post by **velkin** » Mon Jul 18, 2022 7:07 pm

Good new! Gas is flowing up to the (old) fuel filter and flushing this out!

Thank you so much for your help PS! Here's a drink to you!

HAHAHA I'm liking this guy...

Post by **velkin** » Mon Jul 18, 2022 7:26 pm

These (2 hoses)were the hardest to replace with the bed on, but i did it.

Post by **PapaSmurf2k3** » Mon Jul 18, 2022 9:31 pm

They didn't even look terrible, but might as well knock it out while you're in there.
Now you know what I suggested flushing out the lines

I've seen that junk flow right up to injectors and clog them up. Makes for a bad day.

PS,
Can I hit you with another question? My Nissan book is vague on how the wires, cap and rotor are installed correctly.

When i attempt to start the truck it pops and backfires (see the wire placement)

Its been a LONG time since I've messed with one of those dual spark plug engines, but what you're looking for very well may be in the factory service manual.
https://www.nicoclub.com/service-manual ... %2Ffwd.pdf
I'm guessing maybe in general information, maintenance, or one of the engine sections. We don't have one saved for 1989, but I imagine 1988 should be pretty similar.

https://www.nicoclub.com/nissan-service-manuals
If you can't find it in there, I'd take a look at the rotor inside the cap and just see how its distributing the spark, then just try and match the wires to the correct cylinders that way.

Unless you had the distributor or oil pump out, you should just need to get the wires in the right places. Here's the layout and firing order. Exhaust is the bottom side:

my book shows a similar diagram but the (autozone) distributor is labeled with i1-e2-i3-e1-i4-e3-i2-e4 and two (2) wires in the middle

That should be for the older ones. Pre-'86 used a different setup.

Just to be clear I have an 89 hb 2.4, and i have 4 intake, 4 exhaust plugs and 2 wires going to the solenoids....?

Post by **VStar650CL** » Tue Jul 19, 2022 12:03 pm

I think you must have the wrong cap, or something else is screwed up. From '86 up all the plugs fired from one coil. Pre-'86 there were two different coils for intake and exhaust, which is why they had that wacko firing order. On an '89 you should only have one coil, so I'm kind of puzzled.

here is a pic of my dis cap without me going out in 102 degree heat to show you.

And to be honest I cant be 100% on which is intake and which is exhaust for the plug or coils.

bc each hole has i and e on either side of it, Very confusing for a public school boy.

If that's the original cap style then I don't get it, but the 2-coil setup is like this. The exhaust coil is toward the front of the truck:
