I am having the same problem in a 79 camper. It was running great until one morning it would idle. The tank was run almost bone dry so that is probably the culprit, also there has been tremendous humidity being in Northern VA in Aug. I bought some fuel line cleaner that is supposed to absorb water and keep the lines and injectors clean. I have yet to see if it works, but suggest this a $2 first step.
the idle jet in the carb is blocked and needs to be cleaned out and reset
My 1998 E320 did this. Dealer charged me $1,100 for the fuel pump and filter.
My 1998 E320 did this and it was the fuel pump. The dealer also replaced the filter and it was $1,100.
you need a new cam positioning sensor installed
Could be the starter relay.
it could be the starter. Mine did the same thing and i changed the starter and it works good now. When mine would be hot it would not start but it would start right up when it was cold.
Check the fuel pump?
A poor earth could be the problem here, or a bulb incorrectly fitted, but also a faulty flasher relay could be held responsible.
Try for a cheap fix and change your gas cap. Sounds like it could be vapour lock.
Do you have your terminology right....The injector relay would be the computer right??? The fuel pump relay could cause that problem!!!! good luck and let me know
Your fuel pump may not be able to keep the pressue up, because of either a worn pump or clogged fuel filter, or clogged tank filter.
Check the fuel pump relay.
