hello all, i'm new to the forum and to volvos. i've always been a fan of 5cyls just never had the opportunity to own one. i recently purchased a 1993 850 glt.(pics coming soon) Overall i think its a great car, besides the wrong wheel drive lol. but anyway. the Po said the car had been sitting for a while and that in order to run it needed a fuel pump or that it had bad gas. He also said the car had the engine replaced in 98 after running the original engine low on oil. anyway, the next day i piut a battery in and gave it a few cranks, it cranked fine but no start. i sprayed some ether in the intake and i got it to fire up, so i knew the issue was fuel. i removed the line from the fuel filter and cycled the key to see if the pump was operation. it was not. i removed the fuel pump and it was a mess. it was seized and would only hum if i tapped it a few times. As far as the fuel goes it was horibly brown. While i was draining the tank i replaced the fuel filter with a spare pump i had leftover from a previous build. New lines, wires and strainer. After the pump replacement and a few gallons on fresh gas the car sputtered to life with the help of ether once again, but maintained a smooth idle on its own. i shut the engine off then checked all the fluids. i went to restart and it took a little longer than before. i figured because of the gas quality. even diluted i figured it would be a little hard to start. anyway, it idled fine, revved great, but then it developed a slight tick then slowly died and wouldn't restart. i tried the ether again and it would only slightly stumble and backfire through the intake. initially i thought it may have been "lawnmower syndrome" but after a few quick checks that was ruled out. my next step was the timing belt. upon removing the cover i noticed that the cover said "B5254S," i took that as a surprise because i thought that all 93 850s had a 2.4... the block read the same. but anyway, i inspected the belt and i was cracked so replacing was due. i checked the timing, and it seemed to have jumped a few teeth. fearing the worst that the valves were bent i went ahead and replaced the timing belt. i checked the tensioner and it didnt seem to leak during compression to install the pin. after the tb replacement she started right up, it still had the tick but i figured if i let it warm up the oil would get on the head and quiet it down a bit as i had changed all the fluids while waiting on parts. the car idled fine, no misses of sputters. however it only revved to 1500 max, then started to idle worse. and now it wont start again. i believe that it jumped timing again, what would cause these symptoms? im guessing the tensioner. i plan on resetting the timing and doing a compression test just to set a baseline. we'll see. Also the blower motor has a mind of its own, it doesn't respond to any input from the climate control and just turns on and off at different speeds regardless setting. I've hear that these cars are tanks, probably because the seatbelts fall apart and they had to keep the passengers safe somehow lol i mean springs and buttons were all over the floor lol same with almost ever 850,960, and 240 at the local parts yard haha. i found a good set and replaced the set that were in the car. also learned that the interior trim cracks if you look at it wrong, very..fragile lol.. anyway i apologize for the long winded post, i just really want this thing up and running.
