Answers :

Either the ram is very new and tight not enough weight to bring it down oror the valve in the pump is not going across to let oil back into reservoir, usually need to power this across.

The engine in my Dodge pickup,diesel cummins, won't start,it has fuel, the manifold heater isn't working and the lift pump isn't working anymore, both were working when we started working on it. I replaced the fuel filter, because it would run for a little bit then die, kept dieing with a new filter so put on a new lift pump, I am wondering if the lift pump and the manifold heater are on the same fuse or breaker. I have checked the fuses and the breakers.

The fuel heater is connected with the fuel pump, if it does not work, the fuel pump won't pump. Manifold heater has separate relays, fuse, and selenoids which are under the driver battery. If you have been working on it a lot make sure the battery is ... 2001 Dodge Ram 2500 Truck

The vehicle fails to start. The lift pump does not presurise the fuel system. Vehicle starts after bleeding is done on the injector pump. vehicle on the road runs perfectly. At idle speed the vehicle "hunts" as if there is afuel starvation. Upon switching the car off, it fails to start again.Every time we clean the tank , oil appears in the fuel. I have used a seperate rubber fuel line from the tank to the lift pump, thinkig there was a hairline crack in the metal fuel line. Filters have been ch

Filter is always dirty meaning the tank is corroded. The clean doesn't get rid of corrosion since there is no special coat remained on the surface. This caused the fuel rail is bad now. you had a great idea to run a rubber line to by pass the fuel ra ... Nissan Pickup

I have a 1994 6.5 chevy diesel pickup that has a problem with the lift pump staying on. I have replaced the injector pump 3 time (all bad). I replaced the lift pump relay and it worked better, but would run rough and die sometimes. I bypassed the relay with a switch and it seems to run fine (this is the way we ran our over the road truck in the 60's). The oil pressure gauge always registers 50# and seems to operate properly. Is the relay connected to a different sensor? Thanks

My 2001 dodge ram cummins engine has now power. Can try to go but goes at an idle or crawl. Can turn off the engie and restart and then it goes fine. I have replaced 2 lift pumps and this has made no change. The lift pumps were taken back and they said had to be something else.

Another post says it might be the throttle position sensor. I have the same problem and DON'T want to replace the injection pump. After all I've read here, this really makes sense. ... 2001 Dodge Ram 2500 Truck

I have a 2001 vw jetta vr6 glx wagon with a manual 5 speed, the water pump bearing has went bad causing the belt to come apart so I need to replace the pump. What literature I have found lists a 50+ step procedure of removing and relocating engine bay items and unbolting and lifting the engine and trans to the driver side to remove the pump. Other information says that the engine can be unbolted from a passenger side dog bone support and lowered enough to allow the removal of the pump because

The engine can be unbolted from a passenger side dog bone support and lowered enough to allow the removal of the pump because the frame blocks it in due to proximity. This is the best & correct procedure. Good Luck! ... 2001 Volkswagen Jetta TDI

Did you check the fuel pressure? there is a sharder valve on the fuel rail to do this. i know you have to have a certain amount of pressure in order for it to run.i think on fuel injection its around 60 to 70 psi.and on throtle body is around 30 to50 ... 1999 Chevrolet Silverado 1500

I have a ford 8000 tractor with a mechanical governed minimec inline 6 injection pump. the tractor was running at 85% throttle, i idled it back & it shut down. will not start now. have changed filters, checked pump timing, inspected lift pump &lines

Sean if you idled it back on a mechanically governed engine you have shut the fuel off to the injectors... turn it back up slowly and possibly crack the bleeders on the injectors to make sure you haven't sucked any air,good luck! ... Ford F
