I have just replaced the fuel pump on my 94 Dodge Ram and have followed all the instructions and tips and tricks that I have found on the net but I try to start it and it just won't start. I checked to make sure there is fuel in the rail and there is. It is a new Master pump, not reman. Any ideas for what else I could try?

Hook up a fuel pressure test gauge at the rear of the fuel rail, pressure at idle, if 45 psi or more the pump is OK. This is the only way to determine pressure. Since your pump is new, if pressure is off, check for kinked or damaged lines, power to the pump and regulator, which in your case is probably new with the pump. Are you getting spark.

Thanks for you quick response. I don't have a fuel pressure gauge but there is substantial pressure in the rail. I am getting spark and it turns over but it still won't fire up. There isn't any priming to the fuel system that I need to do after putting in a new fuel pump, is there. I assume since there is pressure in the rail, it should be good to go.

I guess I should make sure that the fuel pump is what I needed, I just assumed it was as I had been told by two different mechanics that it was going bad. It would whine whenever I got near half a tank of gas, and one day I was driving normal and it started to sputter and cut off and backfire and then just quit for good. I just assumed it was the fuel pump. Could it have been something else, distributor maybe? Would that cause it to sputter and backfire and then quit?

Try unplugging the cam sensor, if it starts you may have a timing problem, as in chain, jumped a tooth!
