'87 N/A to JDM 7MGTE swap. The car was delivered to me with the engine/drivetrain bolted in, nothing else. Acquired a 8601-8808 ECU and wiring harness and the rest of the parts necessary for the conversion. Unfortunately upon draining the oil pan, which I neglected to do from the beginning, I found a nice mixture of coolant and oil. Major sign of BHG obviously. Also did compression test, but as I type this I realize the test was done without holding the TB open. The results on a cold motor were:
1. 120
2. 130
3. 30
4. 150
5. 120
6. 60
I decide to see if it will start, but it will only crank.
Here is everything I have done/checked:
-set to TDC/aligned with cam gears
-brand new plugs and wires
-1/4 tank of gas
-no codes
-checked for spark on no. 6 cylinder so far and ok, haven't checked the rest..
-all wiring connections and grounds good
-all vacuum lines are connected
-motor spins by hand ok
-injector plugs correct
-swapped with another MAFS
-removed CPS, aligned, reinstalled
-checked EFI fuse
Here are some things I have yet to check:
-try new gas
-remove oil cap, make sure cams are spinning when cranking
-wiggle CPS wires
I checked fuel pressure via the TSRM, connected FP and +B, and felt pressure in return line. Even loosened cold start injector banjo bolt and it's getting fuel there.
The strange thing is, after all of the attempted starts, the plugs aren't loading up on fuel, which I don't understand. Putting the bad compression numbers aside, the plugs should still be getting wet if there is pressure in the return hose, unless the injectors are not firing for some reason. Does anyone have any ideas? Thanks.
