my sub did this after i did a optic bump too much i went back a little on the bump and it is ok now

do you have the switch adjusted properly ? do your reverse lights come on in reverse ?

i pulled the adv piston out & cleaned it before i put the pump on maybe the pump had dirt in it ? i am going to change the fuel filter & flush the line to pump just in case dave

ok i did some tests today then it would not advance from base timing so i took the stepper motor off & tried to run the timing manually . the advance piston valve would not move ! i pulled the pump took the adv piston out the valve in the center was stuck so bad i couldnt get it out i had...

i am using a mastertech that has gm software (i worked at gm dio all diesel engs ) it shows actual & desired timing tdc offset is -1.45 i put another crank sensor in it the tdco went to -2.45 i set it to - 1.30 when i drove it home timing stayed at 4 deg while desired was at 12-14 deg...

2 96 1 97 1 ss diesel tuned for truck

i hooked up a press gauge fuel press is above 3 psi wide open it also when i floor it the timing will drop to 3 or 4 degrees it is a dog when the timing is advanced 18 - 20 deg & i floor it it runs great black smoke & all so i dont see a fuel delivery problem the pump was on one of my other...

i changed out the ip today after doing tdco i drove it 2 or 3 mi it started acting up again ! i have checked the harness under the int & the pinouts on the ecm swapped diff ecm all scan data looks ok the actual timing will set at 3 or4 deg when desired is 7 or 8 deg then it will go...

mine does it when the belt wears i think my tensinor is weak pull your belt & see if it goes away

ok i swapped in a crank sensor still does it scan data all looks good fuel press ok i swapped the engine harness [under the intake] still doing it i will probably pull the ip next week does any one on here rebuild these pumps ? what are the signs of low transfer pump press ? fuel sol...

no os filter i have 97 software in the ecu the other truck has a ss diesel tune i will pull the old pump apart &look at trans fer pump & fuel sol adj i already pulled the advance piston it looked ok dave

i would say the stepper motor is trying to correct timing it is moving with the timing noise 2 different ecms all scan tool data looks ok ex the act timing when it acts up otherwise it is ok i can command 0 deg with time set & the act will go to 3-3.5 deg turn time set off goes right to des...

ok it acted up today i drove it about 25 mi yesterday ran good when i started it up this morning it ran rough & quiet / no advance then after running about 2 mins started advancing timing then would back down to normal timing then advance again i unhooked the return line no change then i...

1500 burb diesels have 8 lug non floater 9.5 rears optional 3.73 3.42 gears std 2500 only difference i know is they have 10.5 full floater rears 3.73 or 4.11 gears

i have also pulled the advance piston out & checked the bore also the valve in the piston all free i pulled the return line &put it in a jug it stopped acting up but it was intermittent so i have to run it like that & see. i dont know what a restricted return would cause its probably not it...
