yes as above oil level, but i,d say dont drive the car untill sorted.
could be as simply as a faulty sender unit.
blocked oil filter .
blocked engine oil ways .
faulty oil pump , not likely

thanks for all that info . did you find the s/w updt improved anything.

thanks

good job , lovely clean engine . you obviously learn a lot in the fault finding process. where is this blocked water pipe you mentioned , need to check mine have you go an image please. very interesting post sorry just read temp repair . on fpr you said soft ware up date on e,c,u how does that work ...

try air gun.

can you post a photo of it and its location. might be able to help

i got auto and its 3 pin. tps nothing to do with auto .

glad you got it sorted. its often the basic things that are the problem . but not easy to find.
and you have learn more about how your car works. on the electrics

did you clean out the spray bar that lubricates them. I understand that is the weak, link top end lub on these engines .

if you got corrosion on the wires that could well be your issue.

I think 500 - 550 is correct for cps . but does not prove its working .

You said ecu turns the relay on throu fuse 11. I think fuse 11 just lets the power from the relay to the pump. Multimeter makes a beep sound if i connect one side of the fuse and a relay. yes your right . I shouldn't have 12V on the fuel pump relay when I turn the key to 2nd position right YES BUT p...

As you can see in the wiring diagram the pin 30 on fuel pump relay is live . but the power to the coil inside the relay is made live from the dme relay . then the f.p relay is controlled by the ecu . to ground it and make the circuit. so both the dme relay and the f/p relay must be good for the circ...

your car has 2 pumps. 1 in the tank and one under the car . the pump in the tank has rubber hoses coming from it. as in first photo. the sender only has wires to it. https://www.r3vlimited.com/board/showthread.php?p=4072478&p=4072478&p=4072478&p=4072478 this might help look at the diagram . main pum...

if your cps is knackered , you wont have a spark . another test your rev counter should flicker when you crank engine , proving impulses are coming from it
and check your rotor for tracking . ( black marks or cracks ) needs to be removed to check properly.

firstly . our cars only run the pump when the engine is cranking. NO PRE PRIMING LIKE A Modern Car. in answwr to your Q yes . if the crank sensor is knackered , it wont tell the ECU ENGINE TURNING , therefore no pump. have you check the main relay dme ... that send power to the fuel pump relay . and...

that's strange . thought they were all the 3 pin type. what engine managemnet sys have you got then ? L - jetronic

this is lifted from here wiki section Testing While it's relatively simple to test the Blue Temp Sensor, it is also important to test that the information is reaching the ECU. This test needs to be done first, so that you don't disturb any wiring in the engine bay - especially the sensor plug itself...

check out the posts on here from him. there is a very good one about how to check the blue temp sensor. from the ecu is best .
have fun good luck with finding it

i will be watching this one, as i have a similar problem with a cold engine. it could be quite a few issues. check you icv is clean. is the rubber boot to throttle body o.k . not cracked. fuel pressure , afm faulty , blue temp sensor , injectors, compresion , timing c=belt out. but fav would be a va...

i f you youtube it there are a couple of guides on there about takng the seats apart recaro /sports . one guy mentions welding up a particular weak point. iirc on the hinge bracket don,t know if that's what you are referring too.try this link

no it wasn,t lifted from something you wrote, things I,ve learned over the last few years
(many of which have come from your vast experience of the E30 posted here, all spot on I may add ) but the middle bit was copied from wiki.

o.k noted and thanks for the reply . wonder what the recommended service interval is . and the only reason I posted this is because I thought it migh help someone else . I had this problem i,ve been chasing for years now and hooray finally got it. my occasion MIS FIRE has gone. I did not need to che...

if fact your car has not got a m.a.f on it at all , its a air flow meter. afm if we are talking E30 check it on here wiki AFM After being filtered, the amount of air is measured by the Air Flow Meter. This simple sensor involves a door that opens wider as more air flows. As the door opens, it moves ...

the mass air flow sensor is not used on idle.
idle is controlled by the icv and a by pass rubber tube.

Clean your idle control valve , first port of call .

could be blue temp sensor . could be TPS. NOT ADJUSTED RIGHT

Vacuum leak somewhere.

I broke down the other day and had to be rescued by the goood old A,A CAR STARTED MISSING badly on the Mway, then just died and would not start, following investigation. I had a very good spark from the king lead of dizzy . but weaker sometimes no spark at the plugs . The rotor was knackered, appare...

thanks for the reply Brian. for some reason I can't open the image.

is it a wiring diagram ?

I would follow Brians advice on bleeding , which can be a pig on a 6 pot and if no heat coming from the heater after 2 mins can crack the back of head around no 6 pot. /www.e30zone.net/forum/viewtopic.php?f=2 ... m#p2058239

hi All, has anyone got a wiring diagram for the idle speed control system please , or can they explain to us how it works. electrically I,ve been trying to trace a fault on my 89 m40 . I understand it involves the tps and the blue sensor , i think its basically the same as the 6 pot which has 3 wire...

i believe the law states cars befroe 93 , dont have to have a cat fitted providing they pass the emmissions test . for a vehicle of thta YOM. personally I go pattern part from first pipe from the manifold , then buy the second pipe back box which is quite long and chop of the rear box and fit a stai...

has your car got a cat on it. ?

additional water pump ? where,s that never seen it on mine , or is it only on the earlier models ? prefacelift

sounds like you've check a lot, only one component you didn't,y mention is the CPS. if that is failing could give you all the issues your having.
check out wiki on here

have you tried removing the fuel rail with injectors still connected . cranking the engine . disconnect king lead on dizzy first. and see if the injectors are spraying and clicking. if not stop the cranking . the fuel pressure should hold . remove an injector electric plug then connect twelve volts ...

what was the resistance on original cps. iirc should be 540 ohm . but that does not prove its working. but as you got fuel to the rail , appears the fuel pump is running , can you hear it hume , its under the back seat under a black cover , easy to get at ( it only runs when engine cranking ) it's n...

I read somewhere on other models was hit and miss what diameter struts you have, on the lower cc usually have 45 mm . get a pair of calipers , and measure them the diameter , can be done without jacjing the front up , thou does make it easier. I assume your changing the inserts , inside the strut. i...
