not the fuel filter- still no start.

my cdi still wont start and now i've ruled out the fuel filterso i checked fuel pressure at the top of the injector and i have fuel. diesel fuel. not water or something weird.i have air. i have battery power. but still, the engine cycles but no fire. by some freak incident i suppose all my injectors failed at the exact same time, but i highly doubt it. this really seems like something electrical, considering how immediate my car's stall was.i have no codes in my scangauge either. so i have a new idea, please give me input. the accelerator pedal? unless i am mistaken it appears to not be a cable driven thing, so could i have something messed up in the actual pedal assembly that is sending a weird signal to the injectors. part of my reasoning is that when i stalled, it was when the car was going into a coast, and unless i am wrong, does this car not close the injectors during coast as part of its fuel savings? could the pedal still think it is coast and is thus not telling the injectors to open????i'm just throwing ideas out there, but would love to hear some thoughts.thanks so much

I believe the smart 450 cdi's have a 'drive by wire' gas pedal... No cable.I think the injecters DO close during decceleration,under certain conditions to save fuel.One thing you could look for related to electrical problems, is a poor or missing ground strap in the engine compartment somewhere.This was mentioned somewhere in this thread.Also look in the battery compartment .There was a recall do do with proper water drainage ,and moving up some electrical components in the battery compartment to help prevent some electrical problems.Your dealer would know if your car's been done or not.One other thing to mention, is did you do any drilling in the car, while doing any installations?There are many wires hidden just under many surfaces of this car which are very easily damaged by drilling even the shallowest of amounts, as found out by other members.You may have to consider taking your car to a dealer to find the problem, due to the cars many complex computer controlled electrical systems.

thanks for the reply.i thought about the battery, but when in there, everything is totally dry and cleani have never done any modifying or drilling.and perhaps the most troubling, this is a U.S registered car-so i cant really take it to the dealer, cause we dont have a dealer that deals with the cdi.i like the idea of a bad ground. you have any particular grounds in mind that i should check, and where they would be? thanks!

You can also try disconecting the battery for 10 minutes,and then hook it back up.Somtimes this will re-set computers, fixing problems.You can also contact 'FastEddie',( a member here), or go to his website www.flyingtiger.caAlso try finding help at www.evilution.co.ukAlso stay under this heading 'general vehicle operation and maintenance',( where we are now), and search every heading on every page, till you find the help that works.
