change over relay

[hahaitzskippy]

In the wiring diagram I have, the middle relay is called the vacuum advance control relay and the one closest to the drivers side it the idle speed stabilization relay. Are they the same relay? Can you swap them?

When you start the car, does it die no matter what you do or can you sustain it with the throttle?

oh yes someone responded.

i have been looking for an answer and cant find one... maybe im an idiot and cannot read a bentley manual very well.

as of right now, i have not touched the car since. they are in their original spots. the car fires up and dies, i cannot keep the car running. (with or without throttle). so to answer your question. it dies no matter what.

as far as the relays are concern, i was only able to pull out the "idle speed stabilization relay," have not really tried pulling out the "vacuum advance relay" yet

i guess ill try to pull them both out and let you know how it looks like. i might try and swap them too to see what happens.

another bump?

bump for some m10 love & help?

if it helps, my car is a L-Jetronic system, not the motornic so the parts will be different

ok you m10 engine owners!

my car starts but dies right away. ive practically changed everything i could.

fuel pump (secondary), fuel pump relay, distributor, leads, ignition coil, ICM, DME (ECU), fuel filter, fuel pressure regulator, new spark plugs

i cleaned the injectors, tested the AFM for resistants, tested the coil (old and new), DME (ECU, old & new) created no change, spark plugs (old & new) produce a spark, leads (old & new) both produce a spark, new fuel relay stopped the annoying buzzing, tested the fuel pressure with a fuel pressure gauge and i am getting correct and plenty of pressure.

ok now the question:

how do you know if the change over relay's are messed up? is there a way to check these?

and what do they actually do?

this change over relay is closest to the driver


would the middle change over relay be the "MAIN RELAY" that everyone is talking about?
