2000 S70 radiator core support replacement need help.

[Rocket99]

Wow you aind just kiddin, its a tight squeeze. Got it in, finishing final electrical reconnections.

immediately after the accident I noted the starter would click only, guess I better figure that out before is all put back together

The donor vehicle made it all possible, I could never have done it without especially so quickly

thx for your input, saved my but, this thread on Matthews....

The small 'signal' wire going to the starter has a push-on connector that is known to cause trouble, if nothing else disconnect it and give a Gentle squeeze to tighten its grip on the spade lug.

.... now almost ready for start ..... will need to use jumper cables (need a battery), air filter enclosure not reinstalled presumably that is OK for brief run for a / the moment, intercooler tubes not fully installed, radiator may not be full, it would be test firing only.

is this oK?

Does not crank. Also would not crank immediately after crunch on the day of the accident suggesting direct damage to something not corrected
Definately got a dash board full of lights and otherwise normal buzzers, electrical sounds I'm accustomed to driving this car 2 yrs
I did verify the engine does rotate easily putting 30mm socket on crank pully

headlights not installed
side lights turn signals also
electrical connection to the air filter housing not connected, filter houding not back in yet
Battery voltage a little low at 12.3V

collision impacted well above my bumper, buckled hood, destroyed Radiator pack and support, but the impact did not go deep enough to crunch the engine

The electrical relays etc, 4 of them, at the top of the radiator, feeding the engine cooling fan is not yet reinstalled, and was obliterated in the crash and it could not crank over then either.

Got every part needed to repair this , so far, from a near identical donor car

thoughts:
-swap out engine management computer, from donor car?

Thx in advance if you have suggestions

[misha]

Automatic?
Main ground from battery to transmission housing connected...also from battery to behind driver's side headlight?

B+ cable from battery to starter and from starter to alternator connected?

Starter ok and it's wiring?

Relays on fan shroud should also all be connected.

ETM damaged?

Airbags opened during accident?

[Rocket99]

thx mish... good to hear from you
yes automatic
yes those grounds appear intact, the ground to the transmission appears to connect within inches of starter motor, I assume that is the one you refer to
Starter not impacted in the collision
ETM (is engine management computer?), not impacted, I do have a spare from 2000 V70 R donor car with same VIN 56 engine
no airbags deployed

would not be surprised about those relays, when they got wiped out in the impact, it acted similarly, I hear normal ignition "on" sounds then no more than a click from turning the key. Maybe the system gets confounded and will not allow start with Engine preserving systems not plugged in....
thx

Is the PNP switch damaged in collision?
It will prevent cranking.
Did you tried to start it in N position?

ETM is electronic throttle module.

You can't just swap ecu on a '99+ cars because they are "married" with the car via CAN network and chipped keys.

Did you checked are there blown fuses after accident?

There is really not much that can stop the car from cranking except PNP switch and starter.

All other things would make the car crank but not firing.

[Rocket99]

great suggestions, there is one fuse (labeled starter) does not look blown thru window

there is another (on wiring diagram in Haynes V70 &S80 manual) shows how engine relay is in the starter circuit with another fuse in cabin fuse box

there is a cube relay that could have been toased, shown on Haynes diagram

no damage I see to PNP or ETM, starter was normal before crash

having an intact parts car here: value = infinite

its making sense , will follow up on everything.
thx misha

foggy
"that" small signal wire goes ?where.? This one is solid green.

elsewhere other threads on matthews I'v seen it terminates, or at least has continuite with, continuous with, the lone white temminal inside the engine fuse box area, saw that on another thread on mattnews. My Haynes agrees with differences in color designations. My green signal wire has zero continuity with that terminal inside engine fuse box. That is clearly my no crank deal, slam dunk, That terminal in mine connects to a wire that is green with another color stripe.

Now I think the dense wiring bunch along the front of the engine just above the central motor mount tooka hit in the accident , I need to get into that find that green wire.

my haynes manual has slightly sketchy wiring diagrans covering many many models.

I need one more specific for 2000 V70 XC AWd

[Rocket99]

removed the radiator pack again and radiator support, only way to get good access to starter motor

energized the system, turning the key will not crank it

shorting the HOT on the starter motor to the green signal wire , the starter works fines

swapped out the ring antenna from another car .....no difference

Ignition switch? Green signal wire got damaged. I now think the impressive bundle of wires passing through there, containing the green signal wire did take a hit in the crash, probably how the no crank condition came about.

can I replace the green wire?
