car wont start!!

[mootang]

Ok so it's not the mustang! its a mercedes that i was going to buy for 100 pounds for my dd. it ran fine yesterday when i test drove it but today it would not start. I've checked everything i could. it seems to be getting spark(i put the timeing light on each wire and it was flashing) I havn't checked fuel yet because I don't even know how on this car. I also checked all the fuses. it has an old cylinder shaped coil kind of like the old ford ones and when I checked the voltage on the two screws it was only 1 volt (not sure if that is a problem or not).

P.S. it just cranks and doesn't fire at all. cranks pretty strong though!
thanks for taking the time to help me

Do you have fuel pressure? Do you hear the fuel pump cycle when you turn the key to acc? You may need to take off the gas cap and stick your ear to the filler hole to hear the pump cycle when someone else turns the key to acc.

Does it have a schrader valve at the fuel rails to test for pressure????

no shrader valve, that's why i don't know how to check it.

Please post info on what sort of engine, fuel delivery, etc this car has.

Scott's line of thinking is what I had in mind too. You could pull a plug nd see if it's wet.

Good luck.

thats a good idea on the plug! thanks

its a 190E 4cyl. gas engine.

Ok It started today and I could here the fuel pump prime! before when it wouldn't start I could not here the pump prime! so what would cause the fuel pump to not work and then all of a sudden work again! does this mean that it is on its way out or would this be a wiring problem?

thanks,

Scott, it could go either way. I would be more inclined to look for a bad connection (corrosion, resistance, etc) than a faulty/failing component. That is just my edumacated guess given the climate across the pond there.

Good luck.
