1987 e30 325e start up problem? need help!

1987 e30 325e start up problem? need help!


my car usually starts, now that it has been getting cold, and when i go to start it sometimes, it wont. so ill the put the key in and turn, the engine cranks and sound like its going to start, but it wont. so i let it sit for an average of 6 to 12 hours then try again. every time after letting it sit, it starts right up like it normally does. can anyone help me or have suggestions?

check the cold start sensor/injector...it could be just dumping too much fuel and fluding it...then when you let it sit it will start up normal...

yeah go with what Eurostyle suggested but I wouldn't worry about it being your distributor cap or plugs because it wouldn't do that, and if none of thoese work then have you o2 sensor changed and get your fuel pump checked, it may not be the fuel pump but the assembley to it may be getting fried

WTF? I had this problem and replaced these items and the problem went away, I already had my fuel pump replaced.
How does starting a car not have anything to do with the cap and rotor and plugs

Did you do the work yourself or was it done at a shop? Because a LOT of the time shops will fix a small problem by replacing random parts and charging you for it!!! Just a few months ago my friend had problems with his Golf VR6, we couldnt find the problem for 2 days, he went to a general mechanic shop...they couldnt find the problem after 5 hours of work (my friend was there all along), then the next day he sends the car to the shop that did the engine swap (VR6) in the first place; in about 1 hour the car was fixed, long list of parts "replaced" (distributor, coil, etc...) and it they charged him $500!!! When i came back from europe a month later i checked the distributor and it was NOT replaced, but it was a bit too late to do anything...

Hey man I don't mean to come out sounding like a dick I just know how these things work thats all. See my mechanic and I are good buddies and I also work at NAPA so with his know how on repairs and mine on cost of parts I know what goes on. See in this situation its most likely gonna be the cold start sensor like Eurostyle suggested or the coolant sensor (possibley fuel pump related but their not as unreliable as a sensor in winter). See for you mechanic to change your sensor would be dumb for him because it would cost him more money than it would cost you. One of thoese sensors goes for about 26$ (jobber confidential price) then theres you mechanics mark up and about 5 minutes installation for him, so see hes really not making much off of that. So what he is gonna do is tell you its you cap and/or plugs because they are more costly and time consuming to install so he will make a larger profit out of them. Now hes only doing this because its a ignition related problem, but in this situation its not what needs to be fixed so he just adds to the job to make more profit and at the same time saves you trouble down the road. So getting your cap and plugs changed was a good idea but it wasn't the problem but at least now you don't have to worry about it for at least 70,000km. Once again sorry if I sounded like an ass its just this is how it works buddy but Merry Christmas and happy new year too.

Hey you were saying you took off the air filter and you were getting a fuel leak from your MAF sensor? THAT SHOULD NOT BE HAPPING, the MAF is air not fuel there should be NO fuel comming from there. Have that lookedat if you see fuel comming from there because that is a problem.

,i think if was from the coold start spraying all the time when i try to start it, over and over. ............ . so i got new thremo time switch (temp sensor) and it did not start tonight, it might be the cold or it might not, my fuel injectors have never been replaced, pretty sure i need a new feul filter, not sure if my fuel regulator is correct cause i got it off ebay, its a adjustable one, the presure dropps to 0 as soon as the car is turned off, so on start up it has no presure, mayy thats it i dont know, but im just going to keep trying things me self , if any one has any ideas , i'd love to hear them.


thanks
