Question..
What would happen if the throttle linkage was stuck in wide open throttle position and one attempted to start the car?
I believe in EFI systems that the computer would sense that the car is not started and prevent loads of fuel from being dumped in the cylinders, but what about the k jettronic? my car would turn over but not start, so I pulled the plugs and they were soaking wet, and fuel was actually dripping out of the spark plug hole. I then played with the throttle linkage and realized that the connection between the accelerator pedal and the linkage was broken, and the linkage was in the WOT position.
thanks

K Jet is mechanical and the injectors will only spray at 45psi or greater.I'd say you have an ignition problem rather than a fuel injection problem.Check the ballast.
Hello. Very good information in this post. It have been very useful so far.
We have a w116 280se with D jetronic with starting trouble. It is the M110-engine.
The first problem was that the car was hunting at idle. We changed the spark plugs and checked the following: both temp-sensors, pressure sensor (MPC), throttle switch, aux air valve. We also checked for vacuum leaks and that the fuel pump was running. Nothing helped.
But, when we took out the trigger points and cleaned them the problem changed. Now the engine starts but stops after 5 seconds! When it stops, it also stops the fuel pump. We have connected 12v separately but it stops anyway.
We have measured the trigger points when not installed. But my guess is that they maybe are worn down so they won't work when installed and therefore maybe the ECU stops the engine? I also think the cold start valve helps it start, and when the cold start valve stops, the engine also stops?
How about the fuel pump relay,wiring and ignition switch?
I have 87 300E and wont start,new Fuel pump relay,temp switches,ign.rotor ,gets a good spark and fuel presure to Fuel distributor and nothing to the fuel injectors,is there a way to fix fuel distributor/clean it/ or gota go with new one $1500

Pressure actuator or control unit faulty.With a multimeter,see how many mA you are getting while cranking the engine.
If you read anything,it may just be the control plunger is varnished causing it to jam. Sometimes a rubber mallet tapped dead center on top of fuel distributor will free it up. Overuse of fuel injector cleaner will cause this as well as well as low octane (87)
hi Benz
I need help .
Can't get mine going at all. 86 E 300 I get good spark ,replace ignition rotor and distributor cap,sparkplugs,I get fuel to the fuel distributor but nothing out of it.Got a new fuelpump relay,and Overprotector relay,fuel presure is147psi before Fuel distributor and no presure coming out of it.
just an update
tapping didn't help,I do get reading to it but no fuel comming out untill I press the airflow sensor plate/ don't know if that is what you call it/ fuel starts comming out under presure from fuel distributor,but floods the engine!!!!,so still no start
Should I replace that duel distibutor or there is cheeper fix.
Thank You
i'm Barong,.. i live in Jakarta Indonesia (adityamangoen@yahoo.com)
i own a Mercedes Benz 280 SE (2.8)W116 -1973 which have trouble.
I had an accident,....the engine compartment burned.
I have fixed the body and everything,..and engine overhauled.
The problem is,....the engine can't start.
I have checked :
1. The fuel regulator which have 1 inlet and 2 outlet not working
2. No electric signal to the fuel nozzles. (the wire cheked,...and no problem.
3. I assume the trouble is from the ECU,..
Need help....
1. How can i get the fuel regulator ?
2. How can i fix the ECU or can get the used one but in good condition
3. I need the electricity map/diagram
4. Because of my less knowledge and careless,...now i need a fuel diagram from the fuel tank to the nozzles
I hope you all can help me,...i really desperate,.....
