Question about 1992 Volvo 740
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?
