Hey Guys i have a 93 850 and i was going to leave work today when all of a sudden, my car would not start at all. I was craking it for a good min. (several times acutually) Checked the cam position sensor connector to see if it had somehow come loose or disconnceted. Found it connected. Than checked if i had fuel. Opened the shrader valave on the fuel rail and gas came out. I haven't checked to see if i was getting spark. Now i could hear the fuel pump purge with the key in ACC. So i should be getting fuel. Now just before this dilema i took out all the plugs for an inspection. I doubled checked to make sure that all of them were in place and snug. They were. Also i had just finished washing my car down. And i just thought that i'd mention that the cam position sensor had broken when i was doing the valve cover gasket. I was able to fix it with some RTV. But also i was getting a shuddering sometimes when i would start the car in the morning when the engine was cold. I had replaced the fuel pump relay, the fuel injection relay and the fuel filter last month so i can't see them going bad. I haven't changed the plugs, rotor, distributor etc yet but parts are on order from FCP Groton. Today however i got it started. But shortly died . Tried to start it up again but would refuse to. So i ruled out that i have spark and compression because it did start and idle for about 5min. It only died when i opened the butterfly a bit (about half way). Although when i tried again it wouldn't quit. Eventually it sputtered and then died. I tried again to start it up but to no avail. I hooked up a fuel pressure guage and it was reading 45psi at the shrader valve (not the one on the engine but the one before the filter as the one at the engine was in a tigh spot and i couldn't thread on the line) So i also ruled out that the pump is not the problem and that my injectors must be firing because it did start. I'm stumpted with this. Anyone have any opinions on what it is????? Thannks. I really need this car runnig again as it's my only car to and from work.

 

I forgot to mention too that i had just finished washing the car on Saturday but it sat in the shop on the weekend.

 

you need to check for spark first.if no spark wait for your parts to arrive and install them.(i didnt see plug wires on your list)i would change those too.if still no spark check back in with us

 

Sorry forgot to mention that those are on order too. But ok thanks for the advise and i'll check that tomorrow morning when i get to work. Appreciate the input. Will get back to you.

 

+1 on plug wires; cap & rotor too.

 

Agree with gdog. You need to check them.
