Customer reply replied 2 years ago
No I will but, like I said if I cycle the key it runs smooth, when you start the engine it has high idle upto 2,000 rpm's then when that shuts off it dies, but if you turn key off then back on quickly the engine soots right back put 2000 if you keep doing that it runs on all 4 cylinders just fine
Customer reply replied 2 years ago
It will not idle and it will not throttle, when I push on the gas pedaL it just let's air in but it does not add fuel , also I don't hear the idle air servo , but when I throttle it dies anyhow . Just turn the key it starts perfect every time then dies, you cannot add throttle it makes it worse dies faster leave food off throttle and it stumbles a little before it dies
Ford Mechanic: cloe0626, Auto Mechanic replied 2 years ago

the codes are for a low voltage in the battery circuit but the smoking and fuel smell is a sign of a bad injector staying open and causing to much fuel to get in to the engine will also cause it to run really rough if you ned anything else please let me know and be sure to rate my service when you get the chance

Hello and welcome to JustAnswer!

Was fuel pressure tested under load while running poorly?

Did the problem start not long after getting fuel?

Have you checked for fault codes?

Ask Your Own Ford Question
Customer reply replied 2 years ago
Replaced fuel pump ,and filter has good pressure starts right up no fault codes, then dies ,if I shut the key of then back on while running I can keep it running only because it is cold and thinks it just started, when u start it it goes up to about 2,00 rpms then dies.when u push on the accelerator it dies I guess I will pull the injectors but it does not make sense that I can keep it running by cycling the key

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.

I do know, after going though this with JustAnswer, that I can somewhat trust my mechanic but I will always contact you prior to going there.
