1993 Mustang 2.3L Have to start with gas pedal pushed down all the way

krk105 · 12-15-2008

my 93 2.3L will not start sometimes and then to get it started I have to hold the gas pedal down all the way and crank the engine continuosly till it starts. What is causing this? Is there some sort of choke that is sticking. Also I noticed that it is getting worse on gas.

i have had this same problem. does it puff out black smoke after start up? once you get it started does it stumble? my issue was the head gasket was going slow and my rings are bad. then my engine blew the head gasket completely out and really didnt start lol. do a compression check, check what color the spark plugs are and if you are losing any water and message back.

when you put the pedal to the floor you are putting the car in clear flood mode and there is not choke on you car. Chokes came with carburetors not EFI.

It does not puff out black smoke. It will stumble for maybe a few seconds till it gets up to normal rpms, then it runs fine. I ran the codes and came up with 211 -Profile Ignition Pickup circuit fault. What could cause this fault.

it could be the cam sensor. throwing the timing off can cause hard start but run once you get things moving.

putting the pedal to the floor on efi doesnt mean flood mode. fuel injection doesnt start giving out much till hte car turns over so its basically giving more air to help clear out from closed throttle. you do the same thing with carbs to clean them out when flood.

Putting the pedal to the floor during cranking will disable the injector pulse from the EEC. This is done via the TPS signal. It does this for 2 reasons:
1. To clear a flooded engine
2. To prevent the engine from being started at full throttle. This is very important to a manual trans car that has a jumpered out Neutural Safety Switch!

I've heard this could be from the Cam sensor or crankcase positon sensor failing which would then produce the 211 -Profile Ignition Pickup circuit fault. What are some thoughts?
