It's been a few years, finally got the MS wired up. 2056 with stock 2.0 intakes won't start, all I get is a few pops.

New Yellow top battery helped, the dead Red wouldn't even give me a pop.

EDIS-4 is working, great spark, and I can see the timing mark move when I change the settings in the laptop. (Had to rework the trigger wheel from McMark for the EDIS timing to work.)

New NAPA fuel pump and filter, new hoses, stock pressure relief valve.

Injectors are stock 1.8 with 1.8 resistor block, getting pulses to all of them.

WB EGA is connected to dash gauge, it was setup in air a while back.

Ideas?

I could use some eyes on the laptop, to give the settings a sanity check...

I would check things in this order (based on my own experiences):

1. Timing - this was easier for me because I started FI only and then added ignition control after I had it running.
2. Verify the correct firing order. Remember MS order, ABCD, does not map to 1234. The timing order you specify in the MS configuration does change,the MS firing order.
3. Pull one injector, place it into a glass jar and make sure you are actually getting fuel.
4. Verify the correct fuel pressure.

If these are all correct it "should" start.

Thanks.

Timing is adjustable in MS, I can see my 7.5 mark and it moves if I change the setting.

Firing order is a question. The wires from the injectors are on FastOns so I can switch them around easily and have tried every combination. MS V2 has only two outputs, so I have to pair up two injectors per. Similar to the EDIS wasted spark setup with 1-3 and 2-4 except (I think) 1-4 and 2-3 should be ganged?

Injectors 1-2 sprayed fine yesterday, I try 3-4 today. I have a pressure gauge plumbed in, more or less permanently. It reads 30 PSI during cranking, I saw it jump to 40 PSI when it tried to start for a few seconds yesterday.

MSQ attached, thanks for taking a look.Attached File  2013_11_16_16.23.08.msq ( 29.38k ) Number of downloads: 28
