Question about 1990 Mercedes-Benz E-Class

1986 200E 124 - Starting problem

It takes hell of a time to start in the morning and any time of the day. I have changed the fuel pump, fuel injectors, spark plugs, HT Coil and cables from distributor to spark plugs, ICU.
All shows functioning well, but it takes 15 to 20 minuits to start every time the egnition is switched off.
Fuel distributor/divider shows functioning well with fuel flowing through.
Could you tell me where the problem lies.

Having problems starting 99 Chevy blazer have to chycle fuel after running starts right up already changed fuel pump


First thing in the morning, key on engine off, did you check proper fuel pressure before you changed anything? Do you have proper fuel pressure after changing the pump?


Cycling the key several times before you crank it, helps to pressurize the fuel system. Also, if you have the spider fuel system, that system is noted for problems. There maybe some service bulletin regarding cleaning the fuel poppet valves. Hard start in the morning, starts fine rest of day. The cleaning procedure I saw, was a shop procedure.

I have a 1999 GMC jimmy 4 door 4x4 v6 4.3 ltr automatic with a starting problem, it starts with starting fluid and runs great afterwards can drive all over God's creation afterwards, but day a


Sounds like you are loosing fuel pressure overnight. Since it takes 70+ psi to start and run, if you have zero pressure in the morning, it would take a long time of cranking to get the pressure back up.
If it is low or no pressure, the problem could be a faulty check valve in the fuel pump.

I have a 2003 silverado, it starts fine in the morning but the rest of the day it cranks for a long time before starting. turning the key on and off a few times doesn't help. I have had the fuel pump


If the fuel pump is inside the gas tank, remove the gas cap, to equalize the air-pressure inside/outside the gas tank. That should let the fuel pump "suck" the gas from the tank.

Hard to start in mornings


A common cause is a faulty check valve in the pump. The check valve prevents fuel pressure from draining back into the tank. The pump gets power from the relay for only 3 seconds during crank which would not be enough if the fuel line has zero pressure. You could cycle the key on and off a few times and probably start it quicker if that is the problem.
Have the fuel pressure checked after sitting overnight.

Its faulty fuel pump and clogged fuel filter.In your vehicle the fuel pressure is low,due to this faulty fuel pump and clogged fuel filter,so its not starting.But it starts when you spray liquid in intake.The liquid directly goes to engine so vehicle starts.Replace the fuel pump and filter.This will help.Thanks.Helpmech.

Hard to start in the morning


Either your fuel pressure regulator or your fuel pump itself is bleeding off.Try cycling the key in the morning on and off 3 times to see if the truck starts easier.
