Fuel rail issue or????

[ColoradoCarlisle]

OK, I need some help please

I have a new to me 1988FJ 62 that took a little while to start. Sometimes I’d have to turn the key pull the throttle a bit and then it would start up

I saw a video of someone actually Jonas, who restores Land Cruisers mentioning sometimes when it’s hard to start to possibly change the fuel pressure regulator located on the fuel rail

I ordered an aftermarket part looked like it would be an easy 10 minute job little did I know the rabbit hole I would open up

I took off the pressure regulator from the fuel rail, which looked pretty worn on the exterior so thought the new one would only help

When I was trying to install the aftermarket sensor, unfortunately, I broke one of the bolts that has sheared in the fuel rail

I was able to reinstall the old pressure sensor as the aftermarket didn’t seem to fit. It was extremely hard to push down into the fuel rail, so I didn’t end up using that.with I ended up just reinstalling the old pressure sensor thinking I would drill the broken ball out in the future

That night it started right up. I was able to give it gas and seem to run great for about half a mile and then sputtered and would not really be able to drive underload. It would start up and seem to run fine but then as soon as I put it into gear, it seemed like it didn’t have power and would sputter and barely keep running. I was able to get it started and actually get it to drive home but feel like I was lucky.

It hasn’t had this problem, even though I’ve only had the truck for a month. I’m wondering if this might have been an issue that I have created by messing up the fuel rail or by only having the pressure sensor in there with one bolt or could this be fuel pump or possibly fuel filter?

I did try to drill out the bolt unfortunately, the left-handed stud extractor broke inside the bolt, so my only options are to replace the fuel rail or tap the existing fuel rail with a new bolt

Any help would be greatly appreciated
Not sure if I need to spend more time literally trying to replace the fuel rail or should I start down the fuel pump fuel filter or something else?

Thank you in advance

There is no "fuel pressure sensor" on the 3FE. Are you referring to the fuel pressure regulator? Pics would help.

Do you have a copy of the Factory Service Manual? It has a great troubleshooting decision tree for the EFI system on the 3FE.

You can find a copy of the FSM here, thanks to the fine folks at the @Cruiser Cult. The EFI section starts around page 140.

Yes, thank you sorry it is a fuel pressure regulator. I did include a picture of the part.

Weird, that second photo didn't load for me, sorry about that. I see it now, though.

Anyway, it does kind of sound like you're starving for fuel. It could be any number of things, but if you haven't replaced the fuel filter that would be a good place to start, especially as it's cheap/easy and part of baselining a new to you truck. The pre-filter sock on the in-tank fuel pump might also be clogged. Unfortunately the only way to access/remove the pump on a 62 is to drop the tank, which is a pretty miserable job.

Yeah, I’m just thinking it’s gotta be something in the fuel delivery system It just seems weird. It kind of appeared almost the same time as when I was doing work on the fuel rail.

I’m going to dig into things a little bit more I do. I have a fuel filter ordered. It just hasn’t made it in yet.

Crazy at how complicated this stuff has gotten. We also have a 1971FJ 55 and I’ve had quite a few FJ forties over the years.

This is so much more complicated than just an engine and a carburetor

Highly suggest using a gauge to check your fuel pressure rather than guessing at the problem. It will be time/money well spent. See this post

Thanks for the help
Weird it happened at the exact time I was messing with the fuel rail but it was the filter …….
