This problem and this other thread of mine were part of the same issue.

Turns out it was the ECU, got an identical numbered one and replaced mine, cracked up on first turn of the key

+1 to that

doing the very same thing

so would your next guess be to change the ECU?

have changd the crank sensor once and the ecu is running the fuel pump while cranking the engine, is this not a sign that the ECU is receiving pulses from the crank sensor?

i have been having trouble starting my car recently. i found that i was getting no spark at the plugs. I have read up on how the electronic timing works through the motronic 1.3 to try get an idea of where to start looking for the fault. so it looks like the coil gets +12v from the ignition and from...

hi yeah pretty sure got it right, have a look here:

Pin 11 white/green. pin 13 green/purple like you say but pin 12 brown

pin 12 of my c101 was a brown wire, i went ahead and tried connecting the bulb between it an ignition live, the light just remained on. also stayed on during stomp test

'92 318i m40

i've just checked my crank sensor resistance as suggested on past posts looking for 540 ohms ish. it actually gave me no reading at all, basically infintiy......is this normal for a duff sensor?

when you say engine loom plug, you mean C101? in the engine bay?

as title says........

my car doesn't have the check computer and therefore no check light i'm guessing.

i did try the trick where you press your accelerator 5 times but no light appeared.

is my only option a proper fault code reader in the diagnostic port?

any final ideas on this one before i get shafted at a garage??

just tested alternator wires, no short there.

had a word with a friend last night and he said he can lend me a diagnostic kit. would it be worth trying it?

HI mate, tried car again this morning and got some new symptoms, with the key in the on position but not cranking, everything was clicking as per usual but also the rev counter needle, MPG needle and temp gauge needle were all jumping around. then tried cranking but still wouldn't fire. Just been ou...

might be wrong about the evaporative purge valve, just had a look at ETK and it looks more like the pressure regulator OR at least something behind that......maybe the injectors?? by the way thanks for the help

i link 30 to both 87's and then re attached the bypass wire from the battery +ve to the coil. as soon as i did this the clicking near the injectors was quite fast i think it was the evaporative purge valve but i maybe wrong. also the blue and orange relays were still activating intermittently. still...

connected the wire like you said. ignition lights were on without the key in, guess thats the bypass. the clicking was still there before i started cranking it. when i cranked it, it did feel like it was gonna fire but just couldn't get there.

ok connected the bulb and it stays on while cranking the engine. when key is on but not cranking the bulb flickered along with the other clicking bits

is there any way to check, like shorting some of the connections in the relays socket

the main relay(white one) just started clicking constantly today, but the fuel pump relay has been clicking for a few weeks. i haven't moved any relays around. only thing i've done today was to get to the blower behind the firewall. i'm not sure if this may have disturbed something??

i know weird aint it!!!

just taken this video to show you what is going on. pretty sure the starter is fine because it does crank over just wont fire. The clicking noise is only happening when the ignition is on but not when i'm cranking it over....have a watch see what you think..cheers for help guys http://smg.photobucke...

yep def charged. was running only few days ago but was stalling alot at junctions. back then it was only the fuel pump relay that kept clicking. the main white relay problem only started today.....i think. could it be the ECU?

just had a look at the starter all wires connected. also had a look at a wiring diagram and the white one is the main relay and the blue one the fuel pump relay. still clueless as to why they are constantly clicking

hi guys i have a 92 j plate 318 cab. its basically not starting. when i turn the key and get the dash lights on i'm hearing alot of clicking noises from the engine bay and the fuel pump intermittently activating. if i turn the key all the way it wont fire up just keeps trying. http://img.photobucket...
