I don't want to replace all the sensors,it says one of the probable cause - failed HO2S11 (Bank 1 Sensor 1) hea

Fuel problem !986 Ford Ranger with 2.9 engine,Truck will not start,no electricity any where on the fuel system,replace module,mapp sensor,new fuel pumps,it has low and high pressure pumps,replaced fuel relay. Everything is firing like it should.You can hotwire the fuel system anywhere you want to and the pumps will work,but truck still will not start.Any ideals. PS Already changed computers.

SL2 Won't start; previous codes=PO 133 + PO341 + po420; REPLACED O2 sENSOR - Bank 1 Camshaft Position Sensor Apparently is OK; Resistance=Approx 800 ohms & Output >600 mv; Can't locate Cam position sensor; Think it is near oil filter and has only one wire, but not sure of wire color or sensor resistance or output. Fuel pump relay seems OK; Switched relay with identical one. Fuel pump spins, but didn't measure pressure. Also changed plugs & wires previously & it ran then. WHAT'S

Ok i got a 2002 saturn vue..code was saying bank 1 bank 2 running lean..the vue runs perfect ,sometime at park it would idle hi.anyways i have replaced the mass air flow unit..turn off light,comes back on same code.then they say the sensors on the manifolds..i changed them both upper and lower..turn off light same problem..bank 1 bank 2 running lean...it runs fine...read it could be the fuel pressure regualtor...ok trying to find location,i heard the gas tank on fuel pump,i heard inside the fuel
I had exactly the same problem .Mine was corrected with replacing the O2 sensors .The sensors cost less than $30 each but cost about 20 mins labor per sensor .So if you got an honest mechanic the total cost will be around $130 . ... 2002 Saturn VUE

After replacing the MAP sensor, the Throttle position sensor, the fuel filter, and gas cap-changing the oil, adding Gumout, octane booster, the car still wants to hesitate while first accelerating on the highway or stall when first running after shutting down. If we gun it in neutral, it will not stall... and the gas cap, though new, still has no vacumn when releasing the pressure taking it off. I suspect that there is a hose leak, crack, etc. My son checked it, but that is all that seems to be

Fuel problems 1999 Grand Prix GTP 3800 Supercharged VIN 1: car starts, but shuts down within 10 seconds. You can see the fuel pressure drop within those 10 seconds. If I flutter the throttle, the fuel pressure will jump back up to 50lbs & back down to 0-10. But, you can keep the car running by doing that. I have replaced the fuel filter & helped a little bit, but still shuts down. Replaced fuel pressure regulator & fuel pump & oil pressure switch & still nothing. HELP....

1996 Chrysler Sebring LXi Coupe V6 -- Check engine light came on and had Auto Zone put the tester on the car. Report shows Oxygen Sensor at Bank 1, Sensor 1 was inoperable, fuel mixture is too lean/rich, misfire code, and a code for the fuel pressure relay. Replaced battery, battery terminals, distributor cap, rotor button, and Oxygen Sensor at Bank 1 Sensor 1. The engine spins over but will not crank.

1987 chevy s10 will not run. changed weak fuel pump and prssure is fine now, swapped out ecm, replace fuel pressure switch, oil pressure sensor, distrib cap, rotor, elec chip on distrib, o2 sensor, map sensor, engines runs fine when spraying fuel starter but will not continue to run engine dies. Comments: Jul 14, 2009 - i checked the fuel line going to the carb and it is getting plenty fuel
It does sound like a fuel problem, try running some jet cleaner through as you may have clogged jets. Sometimes, removal of air filter and placing the palm of your hand over the top of the carb's butterfly valve, will clear blocked jets when engine c ... 1987 Chevrolet S-10 Pickup
Bank 2 o2 sensor 1 stays around 420 to 480 stuck in lean comes up with p1054 no activity replaced all 3 plugs on that bank very fuel fowled replaced heated o2 sensor a lot of carbon build up no change bank 1 o2 sensor working correctly switching from lean to rich. even swapped both o2 sensors then bank 2 sensor that was stuck started working perfectly on bank 1. engine runs smooth with new plugs not fouling yet. but will not go into closed loop ever
There is either a problem with the wiring between that O2 sensor and the ECM (Engine Control Module) or "Engine Control Computer" (you will need a DVOM "Digital Volt Ohm Meter' to test those wires) or the problem will be the ECM itself, and the probl ... 1994 Chevrolet S-10

Engine light was on and van was running rough. The local repair center says that it needs a new fuel pump (2 of 6 sensors are receiving low fuel pressure ratings). I keep getting different answers on what this involves. I thought it would just be a fuel pump and a filter, but now I'm hearing there are 3 pieces to the fuel pump system - pump, motor, filter. Want to replace this myself, but I don't want to have to repair it twice. What exactly do I need to replace the "fuel pump"??
First check the pressure at the fuel rail at the top of the engine with a fuel pressure gauge these ar fairly expensive for what they are about a 100$ so if you can borrow one it would be great. doing this ensures you truly have low fuel pressure in ... 2004 Ford Freestar
2004 Volvo S40 2.4I engine check light is on, light is cleared and returns a week later, engine drives normal with light on. codes read P0172 system too rich bank one, P0191 fuel rail pressure sensor circuit range/performance, P1090 fuel rail pressure sensor circuit. now i need to know how to test to see if its the sensor that is faulty or the wiring circuit, replacement of the sensor is over $1000 and cant be returned so need to know im making the right choice by changing the sensor. thanks

I own a subaru outback limited sedan 2002 with the ej251. I replaced the engine and the car ran fine....at first. Now 1&3 cylendars are not firing at all. I've replaced the cam angle sensor, engine control harness, fuel pump, injectors, fuel pressure regulator, map sensor, and tps sensor. All to no avail. What else would cause this. The engine is in perfect timing and no vaccuum leaks have been found. Compression test checks out.
My first thought would have been a failed coil. Most 4 cylinder coils fire odd cylinders together, one positive and one negative voltage.The crank sensor could be faulty too, but I would rule out the coil first. ... Cars & Trucks
