#127 of 163 Failed Injectors by elkotraveler May 22, 2009 (7:13 am)
2005 F150 5.4L: 4 weeks ago I had 2 injectors fail at the same time in full open position. End result was bent rod/scored cylinder and failed catalytic converter. Per dealer, Ford knows about injector issues and has extended warranty to 100K on them. Ford is paying for the repairs without any argument. Issue now is lack of a new catalytic converter - apparently there are none available in the free world. Ford says their supplier will not have them until May 28th (if then) and dealer will not have it until 5 June (if then). Minimum 6 weeks without the truck waiting for converter. Anyone else have similar issues with Ford parts availability? Replies to this message: mad17 (Jun 23, 2009 7:05 am) mickeymouse2 (Jun 23, 2009 7:49 am)
#128 of 163 95 f-250 5.8l efi engine problems by fng1 May 22, 2009 (12:48 pm)
My truck is hesitating or bogging down when I hit the gas, it feels like the motor wants to go but a lack of fuel or power won"t let it. It doesn't do it on the highway just in stop and go traffic and it doesn't matter if its hot or cold. I had to replace my temp gauge because it would go straight to hot when I started it up in the morning. I thought that was telling my pcm that my motor was hot but it still runs like crap. I have replaced the plugs, wires, cap, rotor, fuel filter, one of my fuel pump's and checked the fuel pressure. I also had my battery go bad so I used my buddies battery to start it and want to take it out while it was running and it died after I took the neg or the positive cable off. So I had the alternator tested and they said it was good but I did put a new one and and it still died. If you have any idea's, theory's or suggestions I would appreciate it greatly. I am out of things to eliminate and I don't know what to do next. Thanks.

Replying to: mike9408 (May 03, 2009 9:23 am) Still having the same problem. The truck 91 f150 5.0 EFI will fire right up run good for 15 min or so and then it just quits. Have to let it sit about 20 min or so before it will start up. I replaced fuel pump and checked all connections. I pulled a spark plug and hooked it to the distributor and grounded it and it seems as there is no spark. Is there a sensor that is bad that is cutting the coil off? This is driving me crazy.

Replying to: mike4578 (May 28, 2009 3:53 am) Mike, have you been able to pull the trouble codes from your computer? Your Chilton manual will tell you how to do this. If you don't have one I can maybe send the instructions to you. Otherwise I would check the coil (often when a bad coil heats up it will fail, then as it cools down it will work again for a short period of time. If the coil is Ok, maybe it is the control module in the distributer. Remove carefully and when replaced be sure to use dialectic grease as instructed. Check your connections to the MAF transmitter, check all connections. But the problem sounds to me like it is in the coil or Dist. control mod. Let me know. mj9408sbcglobal.net. Mike9408

Replying to: mike4578 (May 28, 2009 3:53 am) I replaced the coil and the cap and rotor before I started looking at the fuel pump and connections. The distributor has good fire when it is running because i pulled the coil wire off and got a good jolt. The control module is mounted on the side of the distributor? I unplugged the MAP sensor while runnin and the truck idled crazy so i think that it is working. I dont think i have a MAF on my truck. If i do can u tell me where it is? Have not checked that yet. Thanks for all the info Replies to this message: couzracing (May 29, 2009 3:49 pm) diehardford (Jun 04, 2009 12:21 am)

Replying to: cadaverk9 (Dec 29, 2007 5:28 pm) what year is your F150? And do you know the code that came up? should start with P0 if it is 1996 or later

Replying to: couzracing (May 29, 2009 3:46 pm) Would be good to know what is the problem FIRST, then go from there. You should always clean and repair all that you know to be wrong before anything else can be done. Check everything first, if you don't know what to check , please let us know what exactly, the problem is...maybe there is help. Mike9408
