86 190E Cold Start Valve

[littlegirl]

My 190E will crank but not turn over.I have replaced the sparkplugs,sparkplug wires, distributor,fuelpump.The battery is charged but engine will not turnover.

Any ideas ? Read about the Cold Start Valve,how do you check or test it if it's ok ?

Lots of things to check before buying parts. Engines need compression, fuel/air mixture & spark at the right time to start & run.

You mentioned you replaced lots of goodies, but not if you have sparks. Pull the coil wire off the distributor & hold it near an engine ground while someone cranks the engine for you.

You replaced the fuel pump, but did you check if there was fuel pressure before spending the $? or whether you have fuel pressure now? Pull a spark plug & have someone crank the engine while you put a thumb over the spark plug hole for a crude compression check. Look at the plug while it's out. See if it has unburned fuel on it.

If you've got compression & spark, try a (very) little ether (starting fluid).

Spend time checking things before spending dollars replacing things that you don't know are bad or not.

Let us know how you're doing.

For $2. my baby's running again. I guess it just wet and the Ether in the "Hot Start" dryed it out so I could start the engine.
Thanks,
