    Help Major Problems

    I filled up w/gas and wuz leaving the gas station and didn't even get 1/4 mile down the road and it started bogging down then died. I couldn't get it to crank up again. It seemed like it would tried to once then go to turnin over. I figured it wuz my Opti-spark because i had just dun a TB bypass and sum coolant fell down by the opti. I replace the whole ignition system. MSD Billit Opti, MSD GM Blaster Coil, MSD Super Conductor 8.5mm wires, NGK TR 55 plugs. put everything back on and tried to start and wuz doing the same thing. Just trying to pop off once then spinnin over. Then i had 2 go to work(i work on the road). The guy i have working on it said he did a FP pressure test and would be around 30lbs one try and less the next try. They sprayed sum fuel into the intake and they said it tried cranking the best then. I don't know what else to try. And if it matters any it ran completely outta gas about 2-3 months ago.


    Thanks,
    Steven

    If your fuel pressure is varying, that's probably the issue. Fuel pump or possibly the regulator, or maybe both.

    The first thing that came to my mind within the first 2 lines was the fuel pump.

    start with the fuel filter (needs to be changed anyway), cheaper starting point. next would be the pump , do you hear it priming when you turn the key before you try to crank it?

    X2 on the relay, after the filter you should get the relay checked out or changed.
