hello all i am new to this community and this is my first post so i apologize in advance if im not doing this correctly.
i have just purchased my fifth e30. this is my first eta and it is a 1986 325es. all my previous e30's where either i or m3. i never experience fuel issues luckily so this is my first time working on the fuel system.
so here is what i know from the previous owner. not sure exactly why but he changed both fuel pumps. then was having a issue where the engine would stall out once it came down to 3/4 tank and would not start again....then the car was rear ended while it was parked. the damage was not to bad. i bought the car super cheap. it started right up and drove fine. my friend and i pulled out the pump under the rear seat because i could smell gas inside the cabin. we immediately realized he replaced the original pump with a cheap piece of junk. the fuel sending unit was not sitting flush so we corrected that issue also the tapered rubber tub inside wasent connected properly so we re-zip tied it correctly and reinstalled. drove the car down to 1/2 tank no issues. next day drove it to work and when i came back 6 hours later it wouldnt start. had a steong crank but no start (previous owner also complained sometimes it wouldnt start and that he would come back the next day it would start). would almost fire but die out. pressing the gas pedal did not have any effect while starting. came back the next day. filled the tank to full tank and after many cranks it finally started but it was running with a major misfire. seemed to be misfiring at least two cylinders because the engine was stuttering so hard. i pulled all the plugs and 1 and 6 where completely black and full of carbon. other plugs where worn but not nearly as bad as 1and 6. had the car towed home. inwent over all the wires under the hood and found a few things. the wires going to the icv where frayed so i stripped them back and re soldiered them. i also found two connectors on the drivers side. they are directly underneath the power steering res. on the male side of the connector all the plastic has been cut away and whats left is just the male spades they are exposed and jammed back into the female side of connector ( i wish i knew why someone would do this )
the car starts fine now but it still has a really bad multi cylinder misfire. i pulled all the plugs and replaced them. still a bad misfire. pulled the plugs again and 1 and 6 where completed black and full of carbon. i check each plug for spark and had plenty spark. checked cap and the points looked pretty good cleaned and re installed. pulled fuel line off 7th injector and had plenty pressure. also rechecked both pumps and i can hear them working. fuel filter seems to be changed recently....
before i go crazy digging around anymore can anyone offer me advice and next steps. i am thinking bad fpr or icv please advice
THANK YOU IN ADVANCE AND HAPPY NEW YEAR TO YOU ALL
