on the way to the gym yesterday I went down the 5 degree little decline to the entrance of the gym and my 88 240 dl cut power and died i stopped put in in park fired right back up and didnt die again what would of caused it to die it was running great and then when i left it was running great again i did change the fuel pump and filter the one on the frame last year

 

intank fuel pribably bad. Or low gas at thst time????

 

Intank pump bad or low gas at time of occurrence!!

Goldenblock 2 million miles

 

it has 3/4 tank of gas if not closer to a full tank. it so far only happened once but i am not sure when the in take fuel pump was changed last but why would it start right up if it was a fuel issue

 

If its a huge incline or decline... It could possibly move fuel away momentarily from pick up temporarily reducing fuel pressure. Is your main fuel pump aftermarket???

I have a Rare regina 2 pump system and my intank pump does nothing to effect fuel pressure or performance!

 

on my 740 turbo bosch 2-pump system, when the in tank pump went out, below 1/3rd tank, the engine would starve under heavy acceleration in a mid gear and mid to upper RPMs, also the main pump was quite noisy even with a full tank. new tank pump, main pump went back to silent.

 

when i replaced it i went with a factory pump on the frame that i got through volvo of Palo alto its maybe a 5 degree decline
