Ford F-150 - 1997-2003 :: 2000 - Cylinder 4 Not Firing And Injecting?
My neighbor has a 2000 f150, 5.4 liter gasoline v8. The number 4 cylinder is not firing, additionally the injector is not putting any fuel in the cylinder either. We swapped coils, and plugs, problem stays in number 4 cylinder. He had a new computer installed but problem persists. I am trying to get a chiltons on order so I can see a wiring diagram, I'm wondering if the injector has any bearing on the coil, with respect to getting a fire/no fire order? What is upstream from these components?

just bought a 2002 bonneville sle 2 weeks ago. First few dats it ran great, then it started missing. Dealer had his mechanic look at it. His diagnostics said #1 cylinder wasn't firing. I replaced plugs and wires. Then mechanic said injector wire to #1 cylinder was dead. He messed with wires and got the miss out of it. Today it's back.

We have a 1992 Pontiac Trans Sport with the Chevy 3.1 V6 TBI engine.
Engine was running poor because of a faulty Coolant Temperature sensor (rusted-out pins). Changed the sensor and cleaned-out rust from the socket and now it runs smooth when cold with decent acceleration.
Problem is that cylinder #6 is not firing when engine is hot at operating temperature. Engine shakes lightly but performance remains good.
Distributor, rotor, spark plugs, spark plug wires and Oxygen Sensor were all changed 1 week ago with new ACDelco parts. What to check next?
Accord :: 93 EX-R Running Rough And Engine Light On - 3rd Cylinder Not Firing
I started the car the other day and it was running really rough and engine light was on. I started pulling the spark plug wires and pulling #3 didn't make any difference in terms of decreasing performance where the others all did.
I've replaced the plug, and distributor cap. I've also confirmed with the plug out of the block that it is firing.
I'm not sure at this point what to look at next. This happened overnight, not gradually over time, and apart from running rough the engine isn't making any noises which based on sound, and how fast it happened doesn't make me think its a scoring/compression issue.
Ford F-150 - 1997-2003 :: 1999 - Engine Shutter / Not Firing On All Cylinders?
i have a 1999 F-150 2x4 witha 5.4 liter v-8 with 151,000 miles. Last week the truck began to run rough when i accelerated (ideled fine)and felt like it wasn't fireing on all cylinders and was puffing white smoke. A few minutes later the battery light came on and the truck lost all power and shut off. I replaced the battery and alternator and everything ran fine for a week. Now the issues have come back but i'm not sure the alternator and batter have gone bad again. What could be going on? Have the coils gone bad?

Trucks throwing codes for cylinder 3 and 8 misfire. I pulled the plugs and both were covered in oil and cylinder 8s electrode was literally gone. so I replaced the plugs and within 5 miles it was missing again. so I replaced all plugs, all wires and coil packs. cylinder 8 plug had fouled out. Its a 4.6l 99. I have a mild exhaust leak where the manifold connects to the downpipe. but not bad enough I feel it should matter. it runs rough until about 3k rpm and then it kinda straightens out.

1999 f250 ld, 5.4.
Started running rough, checked codes. Initially got po300, po304. Reset, and when I checked again, had po171.
Checked the PCV lines, and found a split right near the throttle body. Of course. broke the plastic tube trying to pull it off. Replaced the short piece of hose with a longer piece to make up for the broken plastic tube.
Now, po171 is gone, but the others remain.
Cylinder # 4 looks impossible to get to. I would like to swap COPs to see if the code moves.
A. does this make sense?
B. how the hell to I get back there?
At a minimum, it looks like I have to disconnect a bunch of hoses, and maybe even remove the fuel rail.

My truck has developed a misfire on cylinders 1 and 5. The OBD2 scanner at autozone says code P0300, Po301 and P0305. I bought a new set of plugs and wires. Problem still there. I then replaced the both coils. Problem is still there. Is there a control module or something that could kill those 2 cylinders like on the older trucks with distributors?
View 7 RepliesFord F-150 - 1997-2003 :: 1998 4.2 V6 - Low Compression Cylinder 2
Got myself into a tight situation with a truck I recently purchased and seeing if any of you have experienced the same thing or know what may be going on. I bought a 1998 F-150 with 213,000 miles and a 4.2 engine. When I test drove the truck it had a small chugging vibration, for lack of a better term, but the check engine light was not on and it seemed to run great while driving. No problem at highway speeds nor below.
On my way home the check engine light turned on which turned into a blinking check engine light and I knew I had been taken by a person with a diagnostic computer who cleared the codes. He made a comment about it turning on before but his "buddy" fixed the issue but I took his word because he seemed like a decent person.
I took it to a local shop and, if I remember correctly, error code 302 came up for misfire on cylinder #2. He changed the plugs and wires and it seemed to run a lot better. About 5 miles later on my way home the check engine light turned back on, but it still seemed to run smoothly by the time I got home.
The next day I took it back to him and this time we got the same error code plus (again going of my poor memory) error 174 which he said was cylinder #2 running lean. Earlier today he called and said he checked over everything and couldn't figure out anything wrong until he checked the compression. He said the other 5 cylinders were around 130 psi and cylinder #2 was at 75 psi.
Now this mechanic runs more of a brake and exhaust shop so his next statements are why I'm coming to all of you for your opinions.
He said the cylinder was shot and everything inside was shot including the piston, rings, and everything else associated with #2. (I don't think he got in there to really check it out) After scouring the forums I hear more people talk about the valves may not be sealing correctly and what sound to me, to be smaller issues than the entire #2 cylinder being toast.
I'm not sure if I am going to go after the person who sold it to me or not yet but I would like to see what others may think is going on before I light this guy up. I plan on taking it to a more proficient mechanic to do the work, if deemed worthy of work, but would like to kmow where I stand.
Ford Ranger / B-Series :: 1997 4WD - Cylinder Misfires On 4 And 6
Besides being spark plugs and wires and/or a bad coil pack, what other things could make it so i have misfires on cylinders 4 and 6? going to replace the plugs and wires later today when they get to my house but i just want to know what other things i could be so I can evaluate the potential repair cost and should the wires for cylinders 4,5, and 6 be under or over the intake manifold? I bought my truck used and they are currently under the manifold i think it would make more sense to have them over personally.
I have a 1997 Ranger 4WD with the 6 cylinder 4.0L engine. I can't remember the codes that it tripped at the moment but i think one might have been the 304 code not sure though.
I tripped the 300,304, and 306 code but don't know about any others i remembered what codes i tripped the other day when i had it scanned

View 1 RepliesFord F-150 - 1997-2003 :: Loosing Coolant Into Cylinder 1
Ok 210k truck runs great except I am loosing coolant into #1 cyl. Ive owned the truck since 120k and it has NEVER ran hot not even above normal. I guess due to expansion it will even fill up the cyl nearly hydro locking it, no oil in water/radiator and no water residue in the oil either. I had the intake gaskets replaced thinking it may have been it but it came soon back. I really dont think its an head gasket, has there ever been reported problems with the intakes on these trucks? oh btw 97 2wd with 4.6. Even with coolant getting into the cyl it still runs great just a little white smoke.... I really don't want to replace the engine I think it has a lot of life still in it.
