well i got a 86 300zx turbo 5spd. it has 150k miles and last week the fuel pump went out and the fuel pressure regulator started to leak. also it backfired and blew out the maf sensor. it it even worth fixing bein 25 yr old daily driver.

It's up to you... do you WANT to fix it?

Those things are cake... don't be so emo.

alright well i was gonna pull the maf sensor but there are 4 bolts holding it on i can get to the tow on the left but the ones on the right i cant seem to get and also there is a deal in the back of the car with two screws in it is that for the pump or do i have to drop the tank

Time to look in the FSM you downloaded from xenonz31.

The MAF is seriously easy to get out... just gotta remove a few things to get your ratchet down to the bracket bolts.

As for the "deal" in the back... gotta be more specific. There are lots of "deals" in every car. Open FSM... look up efi / fuel pump / fuel tank section... read.

The Deal in the back is not to pull the fuel pump. The sending unit will be underneath that one. You will have to drop the tank to replace the fuel pump. Call Steve at www.300zxpartsforyou.com about the fuel pump. He has used pumps for in the $80 range. Be careful removing the sending unit as the solder joints on the wires of mine were pretty bad and actually fell off.

I would recommend dropping the tank, clean the tank really well and allow to dry a day or two since you have it off and replace the fuel pump. It is not hard but you will need an extra set of hands and an hour or so once the fuel is out of the tank.

Plus, all those parts are only about $200 used from steve. It is definitely worth $200 to fix.

Don't buy a used fuel pump for $80 when you can buy a new one for $100.

To replace the fuel pump, you HAVE to drop the tank.

But if you're having an issue getting your MAF out of the car, then I'm not sure how capable you are with this repair.

Yavin

Yup. If you can get a new one for $100 do that for sure. I couldn't find one that cheap when I was looking and I also needed the entire housing since mine was pretty bashed up from a previous owners "repair".

These are the instructions I used when I replaced mine.
