Hey there,
I'm about four weeks into this headache of a swap and I'm starting to feel a little hopeless.
Let's start with some details. I have a 1984 Volvo 242 thats been a great car.
My buddy and I rebuilt and swapped in a b230ft out of a turbo 940, which I had running happily with a 13g at 12psi on the stock k jet harness with a turbo computer. I have done a t5 transmission swap with upgraded clutch etc...ALL WORKING GREAT TOGETHER BEFORE LH 2.4!
After having noticed that the K jet harness was deteriorating at the touch of a finger, I decided to grab an LH 2.4 harness out of a 93 240 that was in mint condition. After following many threads carefully and swapping a flywheel and yellow 850 turbo injectors my car fired right up for about 2 seconds and then died. I cleared the ECU (lh 2.4 turbo) and cranked again to check codes and got the code 121 (MAF signal error). Easy enough I thought!!!!!
New MAF (confirmed to be good) out of lh2.4, nothing. Checked MAF wires and they had the same figures as my healthy running 91 245. It starts every time I crank but then after a great sounding two seconds, it just dies. It also idles without the MAF plugged in! So it has to be MAF related right?!?!? I have spark, fuel (can hear pumps priming with key), and timing so all systems seem to be ready to go!
At this point, I'm pretty stumped and would love some input from someone who had similar problems. Whoever can figure it out gets beer money through venmo just sayin'
