Engine/Transmission (1998.5 - 2002) Rut Ro.........truck died, check engine light came on

[DKothe]

Driving thru Siloam Springs, AR yesterday in 3rd gear about 1200rpm my '99 suddenly died, I throttled it 2-3 times, no response... ... ... ... . cutting across traffic I coast into a parking lot still in gear and against the engine.

When I clutched the truck was still running but the Check Engine light was on.

Nothing changed other than that.

After picking up my inline 6 cylinder Land Cruiser engine I was headed home again when it hiccuped once more (died but started again before I could do anything).

I had just under a 1/4 tank of fuel at the time.





What does the majority say happened to my truck?



I've got a buddy who's bringing over a fuel pressure gauge in a day or two to see what the lift pump pressure is.

I just bought Geno's banjo fittings but haven't gotten them installed or a gauge to mount on it yet.



Thanks

Sounds like your injector pump is not long for this world.

NOT WHAT I WANTED TO HEAR!

That isn't good news. Going to tap the fuel pressure tomorrow after I get home and see what the Lift Pump is doing. Other than that I guess I could take it in and have the CODES checked on it.



Any other way except having a dealership hook it up??



Thanks

Hopefully, its just something like a Throttle position sensor. Good luck!

The codes will tell you what is wrong or at least what the computer saw out of spec and probably caused it.

Fuel Pressure readings

Installed the Geno's large port banjo fittings tonite along with a grease gun hose, valve and 30# gauge on the outlet side of the fuel filter, from the top of the Geno's fitting.



Fuel Pressure

Idle (850rpm)... ... ... ... ... ... ... . 10. 5 lbs

2K rpm... ... ... ... ... ... ... ... ... ... ... approx 7 lbs



The check engine light isn't on any more either.



Do these pressure readings look okay? Or should they be higher?



Thanks

Normaly you want about 14-16 psi Idle and not lower than like 10 or so cruise and not lower than 5-7 WOT.



I have a pusher 7# Pump and a Mech. Adj. regulator between the OEM pump and the filter with a return to the Pre-filter so even the pusher has a small head pressure... I have 11-14 psi constant, no matter what I do... WOT or idle... . due to the regulator setting. I can set this higher or lower whenever I want.
