2008 f250 5.4 3 valve no codes no flashing SES lightruns with bank 2 completely dead does not hit on 5 6 7 8 cylinders

the lamp means 2 things CEL (SES/MIL)
it means there is a serious problem.
it means get car service
if frisky? it means DIY scan the pCM and check all fuses.
SES lamp is what some makers of cars call the CEL
it means exactly the same thing.
lost the glove box free users guide it tells you all this.
not many 89 cars on the road now, most are dead
and repairs exceed its value (won't stop me but, most end here)

89 Chevy Cheyenne C1500 pickup truck,.
no engine told. generation 4 truck.
4 engines then, 4.3v6,5.0v8,5.7v8 , 6.2Ldiesel-v8

finding 1989 manuals is hard, only paper manuals then no PDF or others doing horrible scans later,
the problem is this cars ECU/ECM/PCM is chevy OBD1 system and there are flash codes (cel /ses ) blink codes for error huge.
if the CEL glows it means 99% of time a major error
like dead sensor , 100% dead,
4.3L has distributor and horrors of TB throttle body injection TBI. not MPI we have now.
5.0 same thing
5.7 -same
diesel ? ask. rare option. for sure running at all.

gasoline engine surge has many causes
i will list some only
spark bad.
fuel injectors messed up. 2 there are.
fuel pressure out of spec, FPR bad.
IAC DEAD OR JUST DIRTY.

NOW THE FLASH CODE OBD1 MAGIC
jUMP ALDL , PIN A TO B.

https://mechanicbase.com/trouble-code/obd1-codes/

a location HUNT AGAIN AND NO USEFUL FACT TOLD.
V6 OR V8 NOT TOLD
no country told at all, yes year, 2005,
The LR3 name was chosen for North American and Middle Eastern markets(wiki facts)
USA IS 4.0V6 AND 4.4V8 GAS ONLY


no engine size told or fuel it burns.
Land Rover LR3 HSE?
what engine, no VIN told and engine code is in 8th digit of VIN
well bank 2 is the bank that does not have cylinder #1
and all V6 (V_n) the cylinder 1 most front, off set. to the front.
the front means nearest crank pulleys.

Discovery 3 / LR3 (2004-2009)?

3 engines LR3 and one 2.7L diesel, so is it gas or diesel>
v6 or V8 and not told. and is and engine 100% questions.
WANTS 2 CMP SENSORS OR JUST 1.?

4.0 L Cologne V6 (petrol) CAM CHAIN HERE LOVE TO FAIL SO IS NOT BAD CMP ITS CHAINS, I BE, EVEN AT 50K MILES FAILS.
4.4 L AJ41 V8 (petrol) BANK 2 IS LEFT (DRIVERS PERSPECTIVE)
RIGHT IS #1 BANK AND CYLINDER



V8
2 CMP
LEFT BANK, TOP LEFT INSIDE OF VALVE COVER. BANK2
RIGHT BANK , TOP FRONT OF VALVE. COVER, BANK1

FIRST GOOGLE HIT. ! V8, CMP BANK2
BUY AND READ THE SERVICE MANUAL IS BEST IT MAY NEED LEARNING MODE ACTIVATED.

Bank 1 is generally the cylinder bank closest to the firewall. Bank 2 is the one closest to the radiator.
Sensor 1 is the one in the exhaust manifold.

If the OBD code says it is running lean, you find it is covered in black soot when you remove it. With the new one in, you may get a running lean code as it is burning the soot out. Reset the code, it is a false positive. Happened to me last week.

Set the No. 1 cylinder to TDC/compression. A. Set the timing mark to 0 on the timing chain cover by rotating the crankshaft clockwise. B.

Component Removal Guidelines 1. If engine disassembly is required that involves removing the camshafts or timing gears, set the #1 cylinder to TDC compression, wipe away any oil, and mark the following items in relation to each other prior to disassembly: • Timing gears • Timing chain • Timing chain No. 2 NOTE This relationship MUST be maintained. The intake gear is timed in relation to the crankshaft via the timing chain; the exhaust gear is timed in relation to the intake gear via the No. 2 timing chain. © 2008 Toyota Motor Sales, USA T-SB-0291-08 September 11, 2008 Page 5 of 5 2GR-FE Valve Timing Procedure Component Removal Guidelines (Continued) 2. If NEW camshaft timing gears or the No. 2 timing chain are being installed, the two yellow links on the No. 2 timing chain can be used to ensure correct relationship between the intake timing gear and the exhaust timing gear.

Check which side of your engine has cylinder #1. That side is bank 1. Bank 2 is the side opposite of bank 1. So bank 2 is not always passenger side. And since you seem to have extra O2 sensors, I would replace the other upstream and see what happens. Also the mass air sensor can give a trouble code issue to the upstream 02 sensors. Good luck. I've struggled thru this myself.

# 4 cylinder is the middle cylinder on the right hand bank, as seen from the drivers seat. Left bank has 1, 3 and 5 (from front to back) and right bank 2, 4 and 6.I would first swap the coil with an other cylinder and see if the fault follows. If it does, then you know that the problem must be with the coil. If it doesn´t, then obviously it is not the coil. You will need then find out if there is spark and fuel. You could have a sticking valve due to carbon buildup on the valve stem. A seafoam treadment could help in that case.

A flashing SES light means that you are operating the vehicle under conditions that are DESTROYING your catalytic converters! This is not good.

Diagnostic Test Code (DTC) P0305 is defined by SAE J2012 as "Cylinder 5 Misfire Detected".

DTC P1145 is a "manufacturer-specific code" and is defined by Nissan as "Bank 2 Intake Valve Timing Control Position Sensor - High Or Low Voltage"

So, to put it simply, you need to find out WHY cylinder #5 is misfiring and get it fixed. You also need to diagnose the intake valve timing control position sensor circuits on bank 2 to (1) find out if the voltage is HIGHER or LOWER than specification (since the code itself is not specific about which it is). And (2) find out what is CAUSING the voltage to be out of specification and take the appropriate action correct it.

Good Evening. I'm sorry to hear your truck is running bad, however I can give you a few points to check on. Your flashing SES light is because you have a misfire in your engine. The misfire could be caused from things like spark plugs and wires or a cap and rotor, low fuel pressure or bad gas. Or the other things like an intake leak or a bad valve so diagnosing is harder without the code that is set while your SES light is on. So get a scanner hooked up and see which cylinder it says is misfiring and go fron there back to the wire to the cap etc. Hope this helps and if you have any more questions please feel free to ask.

You should have changed the front o/2 sensors if any. The rears just read what the cats are doing and the fronts control the fuel feeds to the engine. Using Aftermarket cats is usually a hit or miss prop on the p0420. U need to find a shop that can really diag this for you because it sounds like only one bank is coding for you therefore bank 2 is ok. Go to IATN.com and find a good mechanic.

well if the head gasket has been replaced you shouldnt smeel any coolant. But have you check your coolant hoses???? for leaks or any coolant on the driveway, when your car has been sitting there overnight!???
