1998 Chevrolet Tahoe died and won't start

I have spark, engine codes are telling me the left and right banks are running lean. As far as I can tell, it's not getting fuel.

    Sorry, I've changed the fuel filter and the fuel pump is perfoming properly.

    I think it may be the PCM.

    How would I check the fuel injectors for pulse?

I would check the voltage going in and coming out of your fuel relay. If that doesn't shed any light, I'd move on to checking the fuel pump. It's possible that your fuel filter or perhaps your injectors are clogged, but unlikely that either would be so clogged that it would prevent your truck from starting. Hope this can help shed some light on your issue. Have a great day!

    That's a possibility, but I wouldn't skip checking the voltage on your fuel relay. It might save you a lot of headache. Good luck

I have an '04 Tahoe with the 5.3 L engine. The check engine light came on so I had it coded with a diagnostic computer. Bank one & two detect fuel trim issues (rich or lean air/fuel ratio). Both say...


check the fuel pressure as if this is not correct then this can cause a problem, check running pressures and volume and also check driving pressures as it could be an intermitant problem. then you don`t say if both bank codes were set at the same if so then maf sensor and possibly a problem with injectors could be a problem. but you have to get the codes checked at the time they set and drive around for 1 week or more or you won`t know for sure.

Misfires during a cold start, shows running lean on both banks. Tried changing the spark plugs and the 2 oxygen sensors before the cat.


I am having the same problem. I have an 2004 Tahoe and have had the same problem for the last 2 years. The funny part is that is never happens in the summer and only happens when it is below freezing for the 1st start of the morning. I recently hooked up to a check engine light computer and I got 3 codes. One is P)171, PO174, PO300- They mean too lean in banks 1 and 2 and a misfire similar to yours. I just replaced all the plugs and wires this summer and I am still having the problem. Does anyone have the same problem or a solution to this issue. I have read that it could be a vacuum hose or O2 sensor that is bad but not sure. Any help? Thanks. Brett

Engine code p0171 right bank running to lean


This sounds like an O2 sensor, there are 4 O2 sensors, 2 for each bank, 2 up stream by the exhaust manifold and 2 down stream by the catalytic converter. However the information you have given is limited, the explanation for the code seems to be missing some information. Ex: right bank sensor 1 to lean.

Spark plug


start with the side of the engine that has the cylinder closest to the radiator.
that first cylinder on that side is number one.from there back it is 3 5 7 .
so thats 1357.it would be the third one back.
on one bank is 1 3 5 7 and on the other bank is 2 4 6 8 just start with the cylinder closest to the front of the truck.

Check Engine Light Problem


Codes that tell you your engine is running lean can be caused by a number of things. First thing to do (and cheapest) is to get some fuel injector cleaner and run it for awhile. Dirty injectors can cause these codes. I recommend lucas brand myself but there are several different cleaners to choose from. The second thing is checking your vacuum lines. If there is a leak it can cause the engine to **** in too much air and cause the codes. Anything beyond that gets into alot of mechanical work and should be done by a certified technician

2002 Tahoe Dropping Cylinder


A tune up will not cure the lean code, in fact an engine miss gives a rich code from the unburned fuel. I would suggest u verify u have no vacuum leaks, also clean the inside of the MAF sensor if so equipped and replaced the bank two O2 sensor, that is the passenger side sensor before the catalytic converter. If u have the money replace both right and left sensors, it is better to do them in pairs.
