Try this one. I just loaded the latest code v2.98.

I have a AMC 360, GM TBI, 55lb injectors, MS V2.2. I can't seem to get this thing to start or even think about starting. I have attached my msq and a datalog of it cranking. Does anything look wrong here?

Duh. Thanks.

I am a little confused. Shouldn't fuel pressure be calculated in as well? Wouldn't my 45LB injectors flow more at say 50 PSI than the 12 PSI of my TBI? The calculator tells me at 200 HP and 2 injectors I need 59LB injectors. Is this calculator assuming a specific fuel pressure? And if it tells me I ...

I just swapped out a AMC 258 CID with an AMC 360 CID engine. I am using a GM TBI off an 88 Caddy with a 4.5L v8. The Injectors are 45LBs I think. How do I positivly identify them?

Now I am trying to get the 360 started and I have the reqired fuel at 25.5, 4 injections per cycle, simultaneous ...

I did some more testing and found that. I made a mistke earlier, I do not get a ground on 87. When the fuel pump is supposed to run I get a ground on 85. 86 and 30 are +12v when the key is on. I get +12v across 85 and 86 when the fuel pump is supposed to be running. That seems to me like it should ...

Any chance the problem is one of the Raychem Polyfuses?

I checked the voltage with the fuel pump relay removed (the center relay - K2). These voltage numbers I got directly off the relay board.

30 and 86 have 12v when the ignition is on and the engine is not running.
87 is a ground
87a is nothing
85 has aprox 0.1v when the ignition is on and the engine ...

My fuel Pump went up in smoke yesterday (literally). I replaced it with a new pump today. The problem now is that when I am not getting any power to the fuel pump. The stimulator fuel pump LED lights up when the MS is connected. I replaced the fuse and relay on the relay board with no help. I have ...

I think I fixed the problem. I updated the MSII code from 1.00 to 1.31 and everything started to work. Now my fuel pump went up in smoke. Whats next?
