2002 Ford F150 4 6 Cuts Off and Will Not Start Again Until Motor Cold
Q: Engine cranks but won't start. 2002 Ford F150
Occasionally engine cranks but won't outset. Getting worse. I had fuel pump relay checked and it was skilful. Purchased a new one anyway. Checked fuel pressure once information technology started. Information technology was 32 psi. Lost less than 5% when close off. Replaced fuel pump. Withal having same problem. Not getting any codes related to fuel system but I don't ever hear the relay or pump engage when I plough ignition switch on. Sometimes it takes 5 to six times earlier I hear it and it will start. First to think it's the computer/module. When driving it runs fine and never dies. Have this problem but when I shut engine off. I have gotten a p0174 code and take fixed everything related to that merely information technology'll come on sometimes within x miles and sometimes after 300 miles after clearing code. Delight aid. Driving me nuts and I can't afford a new vehicle payment.
My car has 152000 miles.
My machine has an automated transmission.

How-do-you-do - the lack of consistent fuel pump startup is, to me, telling. I would re-check fuel pump relay and wiring again , including the pump ground wire, for good connections and consistent power to the pump. And, I would also supervene upon the power relay for the Ability Control Module (information technology'south next to the fuel pump relay I believe). If the "no start" continues, check for spark at the plugs to exist sure in that location is no ignition issue. I would recommend an inspection of the fuel and ignition system by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this trouble, give y'all an accurate cess of impairment and cost estimate for repairs.
