Hello all. First off I have spent several hours searching trying to solve this issue... I've been dealing with diesel too much. haha

Car: 1984 190e 2.3l 5 speed

My brother bought this years ago. (I've posted on this forum about it) He typically drove 190 during the winter. He did this because of the hot starting problem. It's been there for years, It has gotten worse recently. I bought the car from him and have been driving it the last week.

Engine below 80f: Engine cranks and starts in 5 sec or less.
Above 80f (sitting all day, but outside temp is 80f plus): Cranks and starts in 10-15 secs maybe more.
Engine fully warmed up: No start.

Honestly starts better the colder it is.

I've use a spray bottle with gas.. Sprayed into air intake, and it will start. Brother has used either, but I'm not a fan.

Things done: OVP relay fuse ok, jumped ovp relay pin 30 to 87's, ok. Fuel pump relay jumped 30 and 87 for 2 mins during no start after getting home from work, no start still. Eng cranks fast. Has a new battery. About 2 years ago it got new spark plugs, cap and rotor. Less than 20k put on since then.

Read possible causes as fuel accumulator, cold start valve, weak spark, ovp relay, cracks in solder in fp relay, and cis distributor.

Lots of post seem to indicate accumulator as the problem in this instance. I thought that running fuel pump would rule it out. Is that a false assumption? When I get time I'd like to check to see is accum is leaking past diaphragm.

Anyways before I spend $ on parts.. Just hoping for input. Thanks
