I have a 1986 740 gle wagon I can not get to start at all. No spark, no fuel, New harness under the hood changed that issue along with new ignitor and ig coil. I've decided at this point since the shop it's at has taken 5 months to work on it to just switch the guts out with a known working volvo. My donar car is a 1984 240 DL.

How much interchanges off the bat with the 240 and 740? Computers have the same connectors but different amounts of pins, injectors, air flow sensor, and stuff under the steering column look identicle. Has any one else mixed and match these two models before and what was your experience?

If you know the specifics, its a piece of cake!

Otherwise, spend hours examining wiring diagrams.
