do not have a key fob, just a key. so do you think it's an anti theft guard? where is the injector relay?

which electronics? how do you match them?

I just used a light to see if the fuse is getting any power and it is getting power after i stop cranking but not while the car is turning over. the light stays lit for a few seconds after i stop cranking then shuts off.
I would have already trailered it to the dealer but it is a 2 hour drive.

I just installed a replacement engine, I have a spark but no injection. I have fuel pressure at the rail and the injector fuse (#6 in the engine bay fuse box) is fine. Car will run when I spray ether into the intake manifold so I know I have spark. Car was running when the old engine threw a rod ...

I have a 2001 V70 T5 2.4L with the Xemodex throttle body.
It blew the throttle body/TPS fuse twice (#7 fuse if I remember correctly). We took off the intake manifold to remove the Xemodex and found quite a bit of water in it, probably about a quart of water.
We have been losing coolant but could not ...

I also unplugged the vacuum control valve and the car ran just as crappy as before.

UPDATE, I just checked the vacuum hoses front and back, forwards and backwards and can't seem to find any leaks.
Next I'm borrowing my cigar-smoking buddy to come over and blow smoke into the vacuum system to see if any smoke leaks out somewhere...

This thing was running excellent until about 3 days ago, when cold it starts and runs fine but when it warms up all hell breaks loose.
It started stalling at stop lights. When in gear I have to juggle between the break pedal and gas pedal to keep it from stalling, when in neutral the idle surges ...

Installed the crankshaft position sensor and it was still stalling...for the heck of it I unplugged the MAF and voila! Stupid thing runs like a top. So I ordered a new one for *gulp* $137.00 American dollars...
Meanwhile this thing is running like Seabiscuit on crank!
I'm having second thoughts ...

Found it! Autozone has it for $71 bucks.
thanks!
