If you have a multimeter, you can check it :
crank position sender:pin1 + pin2 = 860-1060 Ohm is good
the other sensor on the clutch bellhousing:pin 1+3=100.000 Ohm is good
throttle position sender:pin18 + pin3 =infinite Ohm when throttle is wide open; pin2 + pin18=infinite (always, or the sender is gone...)..
AFM:You have from left to right pin no. 5-9-7-8, they are numbered in the AFm plug...Pin9+7=Ohm value increase costantly as you open the inner AFM flap ; Pin 7 + 8 (temperature sensor inside the AFM)= costant increase also here ...
If some of these paramethers are not the same in your car, you have found the the faulty part.
Temp sensor parameters(not so useful, in this case, but I wrote here some good stuff for everyone else, just in case...):
for Bosch temp sensor 0280 xxx 023 :
-10°c=7000-11600 Ohm,
+20°c=2100-2900 Ohm,
+80°c=200-400 Ohm.
Sensor Bosch no. 0 280 xxx 026:
-10°c = 8200-10500 Ohm,
+20°c = 2200-2700 Ohm,
+80°c = 300-360 Ohm.
Hoep this helps

Hi Francesco,
Some good info there but it may be worth a mention that sensors which ohm ok can still be faulty. If they ohm bad (open, short or ay out of spec) then they are bad for sure but the converse is not always true. the only sure way to test is, as mentioned by another member above, to scope them. Of course "bolt on diagnostics" is another option as fitting known good parts is a pretty sure way to go, as long as there is not more than one part faulty.
It's all fun and games

Phil's (286bhp) post outlines just what a nightmare
this can be. When you've done all you can (power at
the ECU?? .......), it would be time to crack
the wallet open and get Phil to sort it out - if he can't
get it going then nobody can.
The money you spend on getting it fixed will soon be
forgotten when you're out cruising.........

If these tips are not successful, I think that your wallet , dear phb10186 ,will have a bad breakaway before your 635 in the wet.....
If You were near me, I should take you to my friend, who got a BMW programmtester from a old bmw dealer (now there's a market in that place...).

Just to throw my tuppence in,
When I did an engine transplant on my old 528 it wouldn't start and had same symptoms - mine ended up being 4 out of the 6 injectors blocked. Changed the injectors and rail and started within 30 seconds. HTH

Jesus, haven't you got the lowering springs on the
'34 yet? It looks like a 4x4!!
It's well worth doing the front shocks at the same
time. If you're on a budget, the French made Alco
ones are very good and don't give anything away to
the Boge ones. About £70 a pair with the VAT I think.
I've found that doing just the fronts is okay and leave
the back as it is, but it's down to each individual I
guess!

If you are working on the front shockers pay careful attention to the spring carrier base welded to the leg. Look for corrosion caused by drain holes getting blocked. Spate of these failures on e23's recently.

I have several mint e23 complete front legs, these were taken off low mileage dry climate 745s that died.........
I also have some mint e28 m5/m535 legs as well.

Hiab
These with ABS or without?
Good to know you have some, as when mines back from the shop, that'll be one of the first things I'll be investigating!

eta,
I know of that problem as the drivers side carrier base broke with my lowered spings on and scared the cr*p out of me as I'd just gone round a bend doing 65 mph at the time. Was lucky that I had just straightened the wheel at the time.
Drew,
The front shocks need replacing thats why it looks terrible. Am very unsure about lowering this car after what happened to the E28

Unless the front spring cups are rotten, it won't be a
problem. Just clean out and Waxoyl the spring cups
and it'll be fine. Dampers won't affect the ride height
anyway, a common misconception.
A 30mm drop won't be an issue but be aware that
unlike E30 and E28, you can't 'cut a coil' off E34 and
E32 springs as the top and bottom coils are a
smaller diameter than the middle ones!
That car needs lowering badly!

No, no, it needs lowering properly.

I bought springs for the E28 not cut a ring off - thats suicide!! I shall see what its like when the shocks are replaced. I may lower it but only by 20mm if I do.
