Hi there,

I'm new here,
and come with problems :whistle:

living in the Dutch:rockit:

i've I 1998 Chevrolet K1500 6.5 Turbo diesel,

today I put new oil, and filters in the engine and automatic,
a new k&n airfilter (fuel filter is coming!(out USA) hard to find in the netherlands...)

so i've got driving, everything ok

then i've checked with a snap-on mt2500, the injection timing,
even so ok!

than i put the cap on the engine (the gray one, with turbo power on it)

so everything done, checked the oils again,


here is coming the problem:

i started the pick-up again,
now he's rought idling, and smokes while driving.....

trouble codes:
P0231 FP secundair circuit low
P0251 IP fuel metering control
P0370 Timing reflection high resulotion signal 'a'
p1655 ?

any one a idea?

my fuel gauges is coming almost in the red area
clean fuel!

wenn driving, it runs on 8 cilinders!

I think its a electric/software trouble, and not a mechanic fuel trouble
because it's smoking like hell wen driving peddle to the metal


here's a video where my chevy is idling

Welcome to the Forum! Welkom op het forum!

My best guess is something in the wiring harness, electrical connectors and vacuum lines was damaged when you re-installed the Turbo Power cover.

Take the Turbo Power cover off.


For these three codes:
P0231 Fuel Pump Feedback Circuit Low Voltage, P0251 Injection Pump Cam System, P0370 Timing Reference High Resolution, see if you disconnected electrical connections or damaged wiring that goes to the Injection Pump Optical Sensor.

P1655 EGR Solenoid Control Circuit: See if you disconnected vacuum lines or electrical connections at these sensors:

Most of us leave the Turbo Power cover off :HiHi:

the cover is off again....:HiHi:

the trouble code off egr, can i understand, because i put it off :bat:

I hope I've damaged somthing by putting on the cover....

but i can't find anything damaged to the optical sensor....
could i give the optical sensor his last breath, by testing the pump timing :confuzeld


but you think it's a optical sensor problem

checked by air in the fuel-> nothing

the optical sensor got 5v between a-d and a-f

my air flow rate (g/s) is 0.00 by idling

can it be so simple like the air mass meter?

There have been problems in the past using a Snap on scanner in regard to top dead centre offset settings / readings .

Hopefully some of the guys with hands on experience will comment. I,m pretty sure Racer 55 has a Snap on & a tech 2 & knows about the problems in with using the Snap on .He has gone over to the Dmax world , but hopefully will show up or can be contacted there. Turbine Doc had some threads/posts years ago concerning the Snap on in regard to its use concerning top dead centre offset

It is my understanding the Snap On MT2500 has to be set to a 2000 model year for it to be accurate.

Diesel-T is right. Racer55 has posted about this many times. For an example: Click Here

Yes the MAF can cause the problems you are having. You should be getting an air flow reading. The 1655 is EGR related. Did you disconnect the EGR? or is a vac line unplugged or broken? That can also cause problems with OBD2. Is your CEL lit? it should be with the 1655 code.
Try unplugging the MAF sensor and see what happens.
