I have a 92 ford F150 302. Everytime I try to start the truck I MUST push the gas pedal to the floor in order to get the thing to start. it is fuel injected. This has always been the case since this engine has been replaced. I'm not sure where the problem lies. I do hear the pump turn on then off. It will not start by just turning the key at anytime. I'm not a firm believer in it being the filter since it will idle. It could be a pressure regulator but I'm not fully convinced nor do I want to just start replacing items until it's fixed. It could possibly be some other issue that I'm not familiar with.

Any ideas?

Sincerely,
Dan
