no start -interesting symptoms
o.k. fellas, here goes - car starts but wont restart till next day or so . when it starts it takes alot of cranking. all the usual culprits have been checked or replaced. ALL! when cranking it wants to go but doesn't. there was a good amount of oil in the airbox as well as the afm and throttle body. (smoking from airbox while cranking.) have not swapped dme yet. the fuel pmp runs, coil has 12.3 v's and i have good spark. did the thump test on dme rel. and dme itself. car sounds good when it runs. starter is new but seems to crank the flywheel easily, but sometimes struggles to spin it, then at that point, it really feels like it wants to light off. when it does this it almost seems like the battery is about out of juice, but i turn the key off and go for a restart it cranks easy and strong. the battery is new. going crazy and broke. this is so diff. than my 928s4 which i have always worked on. appreciation for any help is an understatement! thanks kevin. enjoying your forum, by the way

brand new!
If they were just replaced and not set correctly, that will definitely cause a No Start condition.
Just my .02 worth since you asked......

Questions.
Has it always done this?
Did it start (no pun) doing this after some other work had been done?
Does it start right up the next day, or do you have to crank it a lot then as well?
I might think fuel related. As in the pressure regulator or damper... or... how does the ground from the battery look and connections at the starter???
Always fun to track these down ....keep us posted...

sounds like fuel delivery issue. Have you checked the fuel pressure yet? I have seen problems with the in tank fuel screen in the early cars, take the fuel line off the pump and see if there is a nice steady stream of fuel running out. Also possible for the FPR to stick and send the fuel pressure sky high, try disconnecting one injector and see if the car will start like that.
Good luck, Mark
