Jamin or anyone...

Has anyone of you ever ran out of diesel on your Isuzu diesel, if so what did you guys do to get the air out and get the truck running again.

My truck ran out of diesel and I'm having the hardest time priming the system to get all the air out to get it restarted. Any tips?
Good question. We haven't done that, yet. But, I have done it with other diesel machinery. It's never fun. Good luck.

Engine type, and reliability

Guys, Jamin, Do you guys know what type and size engine comes in these FRR's ? Is it a very reliable engine?

Jamin, I also have a tree service and intend on hauling a chipper as well. Do you ever lack power when your load is full with chips with the chipper in tow? I wonder what the GVW is for this truck. and whether there are things to look out for with this motor.

Thanks a lot guys. I'm glad I found this thread. I wanna join the Isuzu club now. Happy truckin' ;)

All I know is I have the Izuzu 6 cyl. It is 200hp. And very reliable.

I have a Bandit Model 90 and it weighs around 4,500lbs. I have a 16'x8'x4' chip box. That's close to 19 cubic yards. With all of that said, it is slow with a full load and going up a hill. But, it doesn't bother me. The truck is so reliable, I overlook that aspect.

I hope that helps.

RGVW

The RGVW on the FRR should be 19,500 lbs.
I still am trying to find out the correct name of the "fuel delivery module" since the shop doesnt recognize the part by that name.

Priming

There is a priming pump located on the driver side of the engine block to be opened and pumped up to push air out. You need to crack open the fuel lines to allow air to escape from the injectors. Just opening the line a bit is sufficient to bleed the air off. You should then see fuel escaping once the air is removed. it never is easy so never run out of fuel. Messy too with that diesel fuel.

2000 Isuzu FRR Power Loss

I'm having the same problem 2000 isuzu ftr when the light goes on loose power.
The previous owner changed turbo,injectors. I changed all filters battery alternator.
Everything is fine runs good except when that light goes on. Sansar41 did this work for you? Please help
Well, I took my 2000 FRR to dealer for loss of power. Found one injector dead (replaced), Fuel Delivery Module was failing (replaced), Fuel filters replaced, and finally had the valves adjusted since they hadnt been done for quite a while. Have only 159,000 mi on the truck and never a prior problem. Happy to have such a good running truck. The Fuel delivery module is located on the driver side of the engine next to the fuel priming pump.
Hope this helps anyone with similar problems

2000 Isuzu FRR service engine soon light

I am having the same problem as you described. I just bought this truck, drove 400 miles home with the "service engine soon" light coming on and the power cutting in half or worse to nothing. I would start it back up and and it would be alright. It took me like 7 hours to drive that, my heart was in my stomach. The performance isn't necessarily there. It makes me feel better that others have had the problem and been able to deal with it, easily or not. I really appreciate your post and the specifics of what part it took to fix yours. Before this I felt kind of alone in this, being how I live in an area where people aren't as familiar with these trucks. Do you or anyone else have anything else to say about that problem or related problems or just simply any advice, as I am new to these trucks and need all of the information I can get, thanks a lot. :read:

Trapperjohns, Hope U solved your problem. I returned my FRR to the local Ford/Isuzu dealer after about a month because the problem came up again. Dealer replaced 2 more injectors and now I have had no problems at all for months. these trucks can be expensive if a problem arises but I still think the truck is dependable, more so than other trucks I have had. It seems the replacing of the other items only delayed the existing problem but all is A OK now. I figure I can go back to earning $$ with my FRR so I can pay off the last 2 dealer visits and keep bread on the family table. I would hate to replace all the injectors since they are not cheap. Best of luck

I don't have too many thoughts, but, as you have experienced; diagnosing some issues that may arrise on an Isuzu truck can be difficult and expensive. I've only had minor issues with my truck, but they have always been expensive in the long run... simply because the issues weren't well known/common problems.

However, they are still very reliable and well built trucks. My next truck, for my business may be an Isuzu or Mitsubishi. --Though UD cab overs have caught my attention lately.:icon_wink:

Yeah, I was originally looking for Ford LCF's they really caught my eye, still do. But I have what I have and I have a friend in my area who owns an FRR too, so I will live with it and learn. I bought the truck with a few more miles on it than I would have liked, (186,000) and bought it because it was already up-fitted mostly to my liking, (14' dump bed). So I am changing all of the filtering out, fluids and checking codes. I am spending a lot in just small stuff, but I hope the big stuff can be postponed.

I'm pretty sure this was all it was. It is located right under the driver seat, on the block. Hopefully my photo goes through. If not, send me a PM and I'll give you my e-mail address.
By chance do you remember how much you paid for that?? Part? I think part alone is like 300 something dollars?

I've got an Isuzu FRR (Inline 6cyl 7.8L & Allison trasmission). 2 weeks ago my "Service Engine Soon" light came on and I suddenly had no power at all. For example, it takes 1.5 miles to reach 45mph. (And don't even ask how it does up hill). :thdown:

The dealer could clear the code, but once it was driven, the light would come one again and the poor performance was there again.

I have noticed this: When the truck is running cold, I have power. Once the truck reaches a decent operating temperature, it pops the light and I get no performance once again. I ordered a ECT sensor and will change this out (just for kicks).

What I have done so far: Changed the air filter, changed both fuel filters (with Isuzu filters). I added BG 244 and I'm at half the tank of fuel since I added the BG 244. I have also unplugged the negative battery cable to reset the computer, but the same problem occurs.

Does anyone else her have an Isuzu commercial truck? Has this happened to anyone?

The Isuzu dealer was the only shop who had the software to read the codes. And it pointed to changing the fuel filters. The mechanics opinion was that if these solutions didn't work, then it may need the injectors to be replaced. Do you think this may be the true problem? Or, are they looking for a $6,000 dollar job to come in?

Thanks much. You guys/gals are pros. It will be like Christmas to see what y'all have to say... 👍
I am having the same problem 2003 frr light comes on looses power turn key off and back on problem goes away till next time it shows 226 and 227 code does anyone know the fix

My 2000 GMC WT5500 (Isuzu FRR) with auto transmission runs fine until reaching 2000 RPM when I get sudden loss of power and "Service Engine Soon" light illuminates. If I stay below 2000 rpm all is fine. For now I shut engine down then restart and all goes back to normal power level and the warning light turns off at restart. Without a load I can usually get engine to 2300 rpm but with load esp on uphill grade I will experience the same problem by 2000 rpm.
Dealer service writer told me it is turbo sensor (cheaper) or the turbo itself is failing ($1,200 replacement) Ouch!!!
What do you think? Does that cure seem correct?
I’m having same problem what was the fix for yours
