Fuel delivery problems
I just finished putting the motor in my svo and can't get it to start. I have done enough checks that I have the problem conered but wanted some input on things that i'm unsure of.
The front 2 spark plugs were black while the back ones where clean. This says i'm way rich in 1 and 2 but very lean in 3-4. I got out the gauges and measure fp at the rail and i'm sitting at about 38 with vac in and 46 or so with it disconnected. That is where it needs to be for my car. I got out the noid light and started checking for pulse. All of the injector plugs showed a pulse. Now they were all kind of dim and not really bright as some poeple have suggested they need to be.
I had a power spike that killed some of my electronics that has caused this engine build. I had the computers injector driver replaced and also had the inline resistor replaced. The only part of the fuel delivery I haven't messed with is the injectors. I did ohm them out and came in at about 2.5-3.0 across the board. I'm not sure if I killed a few injectors or if that injectors drivers aren't working how they should be or what but i'm not getting any fuel in 3-4.
What do you think dead injectors or bad computer stuff? I'll have an answer tommorow night or friday afternoon. Take a guess and i'll keep you posted.

check your voltage powering the injectors.... is that the only problem your having or is there other problems with electrical?..... My brothers car was doing a similar thing... turned out ground wire was partially burnt...
