Question about 2003 Jeep Grand Cherokee

1 Answer

Will not start in cold weather

Recently had a new fuel pump fitted, we were told this was letting air into the fuel line thus when left overnight, it will not start. In normal weather conditions or after the car has been started it runs normally. We have also had the engine heaters replaced, and associated fuel pipes.

Not solution, fuel injectors/ tune up can make a big difference, diagnostics can't tell you anything unless your car is running with engine lights on, timing is everything!

Cold starting

Most common reason for no start cold with a lack of fuel is the fuel pump relay or the check valve in the pump.
The fuel line should have some pressure it it after sitting overnight. If not, the check valve in the pump may have let fuel flow back into the tank. It would take a few minutes of cranking to get it started.
Also, if the fuel pump relay is not working, the pump would not get power until the engine has oil pressure.

2004fordtaurus3.0 engine runs rough in cold weather when started. like today in new york 13degee

You know what...there's nothing wrong with your engine...When metal is contracts...thus causing more friction between moving parts...this is why your motor runs rough in cold weather...I'm gonna give you a crazy suggestion...Have you heard of a "Block Heater" is a heated dip stick that you place in your engine overnight..
this device keeps your oil at operating temp when you start your car....the block is warm...and the oil flows like magic..just pull out your dipstick...insert the block heater...and rest easy...of has to plugged into a 110 volt outlet...You can find these online by Googleing it or go to it a try and let me know....I hope this was helpful....PEACE.....

Mercedes E300 turbodiesel, 1999, is poor to start when cold, almost/is impossible to start when hot. no air visible in fuel lines, all seals etc replaced, new fuel tank strainer, fuel pre filter and fuel...

Yes sir , you have a failing valve, soon it will snap in two....please have your head checked. You can do this yourself by placing a long-handed screwdriver , business end down to each cylinder while pressing your ear to the handle(while engine is running) will notice a definite difference when you hit which cylinder has the bad valve. Also makes sure the egr valve is clean and your exhaust recycle valve is not stuck.( located in the crossover pipe)

1999 Tahoe 5.0 Very hard starting, sometimes requires starting fluid to get started. once started runs fine. Has had a full tune-up, new fuel filter. Fuel pressure has been checked and is ok. 2 different...

The most common cause of this condition is the check valve in the fuel pump failing, to check this hook up a fuel test guage to the fuel rail test port, run the engine for a moment and shut it down, after shout down the pressure should stay within 5 PSI of the pressure at shut down after sitting overnight, if it doesn't then the fuel pump must be replaced, the reason is the fuel drains back to the tank if the valve is defective, so you get air and no real pressure on cold start, A check of pressure on a hot running engine will not show this fault, also make sure you are usine the correct Octane of fuel, Prem fuel in a regular fuel engine will cause cold start and stalling issues in cold weather.
