If If this is an example of the help offered folks I would be surprised if anything got fixed. Gears are different? Speed sensors different? Dude, you've never seen a Volvo. The flex plate and fly wheels for the 2 different years are identical. The issue is, they use a 58-2 sensor ring that the crank sensor has to read to measure rpm's for the ecu. As it is an 8 bolt crank, there are 8 chances to get it right if you guess. No need to though. Manually turn the engine to top dead center. The flywheel or flexplate should then be installed with the blank spot of the sensor ring (equal in distance to two of the dimples, of which there are 58; hence the name 58-2) pointing towards the hole the starter motor mounts to. Voila...you're done.

Ok, the problem you're having is not very common however to solve this you need to replace the flywheel with the one that come with your new engine because the gears on both flywheel are different and the speed sensor will have difficulty reading the gears.Therefore the car will either misfire or not start. Did you relpace the engine with a 940 volvo 93 and up?

Timing for a 1991 volvo 740


Hi, this is how to align timing on a 1991 Volvo 740.
There are marks for all three. Cam and Aux shafts have dots on face of outer gear. Cam lines up with mark on rear timing cover(about 1 o'clock). Aux lines up with mark on seal housing (about 3 o'clock) and crank lines up with mark on seal housing (about 12 o'clock).

Take care

Back fire and hard starts 1991 volvo 740 s.w. do not know where timing marks go on the slant engine


I had very simular problems. Is it running hard with the tach bouncing. I replaced my ignition module with one from Ebay $25 delivered. They run about $120 new Bosch is the best. I also first looked over the whole ignition system and the fuel system only to find a flakey Ignition module. there is a computer to give you codes as well and it is easy to do. It has flashing codes. You can find its instuctions and fault codes on brickboard.com.

Hope this helps

Engine swap, car will not start


It sounds like you don't have the correct flex plate and it is throwing the timing off not letting it fire at the correct time.
