Warm Starting Problems

[jdoug]

2004 Marauder 91K miles I am the original owner.

Have replaced the fuel pump, IAC, fuel filter, checked injectors and fuel system for bleed down of pressure. The car starts great cold in the morning. After it has been started once, it starts hard. Reminds me of the old days when a carb would vapor lock. Have to help it start by using some assist with the accelerator pedal to give it some gas.

Any ideas will be appreciated.

Mine has had the same issue recently. Driving Me nuts. B4 when this happened it was the EGR. I deleted it years ago and it came back just recently.

I too have had this problem. Also a no start for 90 minutes.
I think it's this:
Fuel Injection Pressure Regulator Sensor needs replacing. Ford part 3R3Z9F972AA.
Price was $127.68 at Tasca.
I purchased a aftermarket unit on ebay
For $20.90 from a person here in California. Should have it tomorrow.

I'll inform all when I replace it.

Could easily be the IAT or coolant sensors out of range.

This has been happening to me too lately, sounds very sluggish on starting as well.

My repair called for a new fuel pump.
Old unit Only lasted 13 months.
