Help needed, fuel issue?

[87freerunner]

My 1990 FJ62 wouldn’t start the other day. Wasn’t getting fuel. Fuel pump turned on but no fuel delivery. I replaced the pump yesterday and it ran fine for about 30 minutes. Now is stumbling and almost dying when I give it gas and let off. I’ve checked vacuum lines/air intake and all seem intact. EGR is deleted.
I’m up in Maine and trying to leave to go home to Texas and it keeps giving me issues. My backup plan is just shipping it and flying home if o can’t figure it out. Any thoughts?

Truck idles fine, it’s only when I give it gas and the RPMs come back down does it stumble and almost dies.

Have you ever replaced the fuel pressure regulator? Part no. is 2328061010 but the FPR is NLA, so aftermarket is the only option. Something to consider.

Determined that was the issue, can’t get the part in time so I’m just shipping the truck back home and will deal with it later. Bummer! Thanks for the response and great guess!

There are several other Toyota/Honda/Mitsbishi/Subaru/Isuzu from the 90's that use a FPR that is very similar and interchangable. Go into whatever parts store with the old part in hand and you'll find one that fits.

As much as I’d like to mess around and fix it, I’m out of time. I have to get back to Austin for work and this is the safest bet for me at the moment. I’ve broken down too many times on this trip to chance it at the point. I’ll get it running again when it’s back in Austin.

Back in the old days was the 3FE mailing list comprised of FJ62 and FJ80 owners. I was the odd one with a 3FE swapped FJ60. Frequently when someone would post that they were having wonky fuel issues the FPR was the culprit. Symptoms were seldom consistent. Could be no start once warm and shut off, hard to start when cold, or even running great shut it off and will not start. Maybe Toyota improved the FPR for other models because seldom do other forums bring up failed FPRs.

Yeah this one was pretty frustrating as it presented as a failed fuel pump. Basically killed the original pump, the first replacement, and now the second is likely bad so I’m just going to throw a new one in again for peace of mind after running the truck too long with the bad FPR. Darn it! Always learning something about this truck!

I ended up hauling it back with a uhaul truck and trailer. Did 2200 miles over 2.5 days to make it from Maine back to Austin TX since I had to be back home by tomorrow morning!

I too had a failed FPR that (I believe) eventually killed the pump. Truck ran fine until it wouldn't start one morning, pump running but no flow.

Just reference for yourself or anyone reading the thread to troubleshoot fuel issues... install a 1/8 NPT direct reading gauge to test pressure using the LCE adaptor 1093076 at the cold start injector. Eliminates the guessing.
