I own a 1989 190-E 2.6. Here's the problem, the car is hard to start when cold.
When I pump the accelerator 5 to ten times and continue to crank the engine the car eventually starts. I know compression fuel spark ignition.
I checked the battery and had a load test done on it, it is ok. Checked all the fuses ok too.
When the car starts and is warmed up a little it seems to start fine.
Pulled and checked all the spark plugs to see if any were fouled, all ok too.
Pulled off the air assembly and cleaned the carb. and surrounding area all ok.
I had the compression done about year and half ago most cylinders 150 140 one cylinder 120 ok for a car with over 200,000 miles I think 160 is real good.
I did change the fuel filter maybe 2 years ago and checked the fuel pumps. One was replaced by a mech. The other one is the original.
Just ordered two new AIRTEX pumps and bosch filter, and some other brake parts,
What else could be causing the hard start when cold ie initial turn on. Could it have something to do with the choke mechanism on the carb.
