need help troubleshooting...
1989 NA S5
Bought this car with a blown water seal and have been unable to afford another engine (intermediate housing was cracked). So I put an S4 block in and attached all the S5 hardware.
Fires up but does not run. Will rev to about 3K if I play with the gas, but will die before long.
No EGR, S5 intake, no air pump, no exhaust attahced at the moment, OMP removed and blocked off (premix), 6 port sleeves/actuators and other big valve thingy on intake removed, no vac lines (just brakes, FPR, and boost sensor) all blocked/plugged...
What do I check first?

AFM is hooked up propperly, how do I check it beyond that?
The TPS is missing the cams and I haven't been able to replace them yet...but why would it matter? I can't set them if the car doesn't run and if I could it would only be necesarry if I get above idle.

but how could the TPS be reading WOT? At idle the cams don't touch the TPS... Not much air to the AFM? What do you mean? I'll try the OMP, but the boost sensor is hooked up.
