Default AFM Loaner for 86 944 Turbo

Does anyone have a spare AFM that is know to be working I could borrow for a few minutes? I brought mine back from getting the belts done last week and after I turned it off in the driveway to clear out the garage, it now won't start.

I am getting fuel + pressure
I am getting spark
I put in new plugs for good measure
I double checked the crank sensors
I am getting tach flutter and did the DME relay jumper

Does it try and start - run for a second or two and then die? On the throttle body, make sure the throllte position sensor (limit switch) is closed when starting

It is trying to start. Sounds like it right on the cusp of starting, but just won't fire. I will double check the TB sensor.

Make sure the fuel pressure regulator or damper aren't leaking.

It's not leaking. I installed a fuel pressure rail gauge and it is showing good pressure. Looks like I may be getting it towed back to the shop.

When you say you are getting fuel, are the plugs wet? If you have pressure and spark it should fire unless the injectors are not opening or the spark is occurring at the wrong time. Did you checked the ref sensors with a scope and check for pulses? Also check/replace the distributor rotor and cap. I have had three go bad that looked to be in good shape and would not let the cars start.
