okies I have the following problem, when the engine is cold it starts and runs fine, once it's started it won't really stop. However before I changed the fuel pump it did that same thing for a while then it got worse and it started stalling as well. But once I turn it off warm it might not start up for ten to 20 minutes (before I changed the fuel pump that took up to an hour). Thought it was the fuelpump relay, however I changed that before I changed the fuel pump. Found out it was one of those aftermarket replacement ones. Here's the kicker I'm thinking that whoever installed that aftermarket fuelpump relay switch, did it in some way that now after a while is screwing up the whole system.
My theory, is that it's better now because the new fuel pump can handle not getting enough juice and that's what broke down my last fuel pump period. But I dunno why it would not be getting enough juice, and the only way I'm gonna fix this if I can find a complete circuit diagram for the 92 4cyl efi mustang so I can figure out where this person screwed up with the aftermarket fuelpump relay, I can tell you it doesn't even look close to the wiring a holley aftermarket wiring is, but in order to really fix this I need the complete circuit diagram for a 92 4 cyl. anybody have a link for me before this new fuelpump get's damaged
