I have to turn key and give gas for more than 30 seconds until truck finally fires. Once it fires I have to give a little gas for a minute and then it runs fine. It has new plugs wire and distributor cap and button all replaced within last month. I do not think it is fuel because the bleeder valve on the fuel rail is getting gas to it. My friend suggested my timing could be off but I am not certain bad timing would create this problem.

Have you checked fuel pump pressure? Will the truck start quickly with starting fluid? Does the truck run good after you get it going? Is there any chance of a fuel leak?

I will try the starting fluid this evening to see if it fires quickly with it. Once it is started it runs good. I don;t think there is a fuel leak. I am not sure if I hear the fuel pump pressuring nut I think it is operating correctly.

I checked to hear fuel pump again this morning and I do hear it. It is only for a second but I believe it is pressurizing I will try starting fluid just to see what I may discover.

I would recommend checkng the pump pressure and pressure drop off when the key is off.

Here is a how to for checking it.

Pay attention to how quickly the pressure drops when the key is turned off.
