Sisters Volvo 740
Has had problems on and off with misfiring.
Have to tow it home one day. "it stopped, fix it"
Ok, start by checking fuel, it pumps fuel.
Pull a sparkplug, no spark, fuuuu its electric.
Coil has juice.
Check the timing thingy-majig on the flywheel.
The piece of shit thingy-majig holder made out of aluminium brakes when i touch it. Fuck.
Spend rest of day driving around, checking friends junk piles. Nothing, have to order part.
Get shitty aluminium part, and new thingy-majig. Now has spark, doesn't start. Pull all the plugs, to do compression test, the last plugs decides to take the thread with it. Motherfucker... 4 spark plugs, 3 different brands. Who is this cheap?
Have to go buy gasket kit and sparkplugs. Find a cylinder head that only has 62 000km on it at friends. Got it for free, because the timing belt snapped last winter out on the ice.
Tear old cylinder head of, drive home, tear broken cylinder head of, smack on new gasket, drop cylinder head on my fingers. BOOM done.
Check compression, fine. Put in new spark plugs. Crank engine, not even a cough... Lambda light now on.
Swap LMM and Oxygen sensor, had those laying around from old projects. No life, give it starter fluid, starts and dies. What, it had fuel?
Now gives no fuel, must be fuel pump relay (common problem on these) resolder it. No dice, swap in a brand new one, nope.
Crawl under car with a battery and two wires, pump is fine. WHAT
Crawl out, steam pouring from my ears. Get gas can out of my own car, pour 5 liters in, car starts. MOTHERFUCKER
Friend is laughing so hard he falls of his stool...
Never have I felt so much like an idiot...
