SOURCE: 92 suburban 454 v8 failed smog .

First I suggest that you have a code check done Most large parts outlets will do this for free.Control module problems will usually set a code. Just offhand, I'd check the egr valve to make sure the valve is clean and properly opening/closing. If the inspection readings were close but not perfect, sometimes "cheating" a bit by adding 2-3 oz of acetone per 10 gal. of fuel will clean it up a bit. It will not harm the system in that concetration,and will also clean the injector.

By "throttle body carb" I am assuming you to mean that the engine is equipped with Throttle Body Injection (TBI). The O2 sensors on that engine do not even start working for about 5 minutes. They are not going to cause a problem on start-up. A fuel filter will most likely not cause a problem on start-up or idle either. A fuel filter is most likely to cause problems on acceleration or when pulling a hill. A more likely cause would be a n Engine Coolant Temperature (ECT) sensor. If one of these is reading too low, it will cause the engine to flood and smoke black out the exhaust - especially on start-up. (LIke a choke sticking on an old carbureted engine.) If your truck is equipped with a gauge, there may be 2 Coolant sensors. One for the gauge and one for the computer. If you replace it, make sure you are replacing the sensor for the computer.

If you can jump start it and it stays running....I am assuming that you connect the Jumper Cable Ground to something other than your battery. If so, Your negative battery cable is suspect. Check both ends for ANY corrosion or loose connections.

When cold my '93 suburban dies but once warm runs fine it has a 454 with tbi


Have you checked to be sure the idle air control is working properly and also the engine temp control sw. The iac only comes on to maintain the idle when the engine is cold. The ect sw monitors the outside temp and tells the computer how much fuel to put to the engine. Hope this helps.

96 Suburban v8/7.4L/454 K2500, Knocking Noise??


sound like an internal engine problem. either one or more of the pistons has "piston slap" and that knocking will diminish as the engine warms up or possibly a rod bearing is worn out. have a tech do a manual oil pressure test to make sure the oil pump and main bearings are ok. piston slap or knock that decreases when the engine warms up is not that serious, but a rod bearing knock or possible oil pump failure should be taken care of asap.

Hard to start and won't stay running


Put fuel in it,then check the fuel pressure with a gauge. The tank unit maybe giving a false reading.

454 ci gm turns over hard backfires timing ok acts flooded


Check fuel pressure, and regulator. A leaking regulator gives a warm engine more fuel [ it does not like it] a cold motor does. same as a flooded motor. Good luck
