#233 of 449 1998 C/K 1500 gas gauge rapidly fluctuating
Apr 12, 2006 (4:46 pm)
The fuel pump on my '98 chevy c/k 1500 died a couple weeks ago. 115,000 miles on truck. Pump was loud from the day I purchased truck new. For those of you who also have a loud fuel pump, a day or two before it died I noticed the tone of the pump changed. Also, the engine wasn't cranking over on first rev. (I usually put ignition key to on for a few seconds to pressurize gas system before turning key to start - engine alway starts after 1 rev). Anyways, I had to replace the whole fuel pump assembly. A couple days after replacing it the gas tank level indicator/gauge started to continuously fluctuate rapidly about +/- 1/32". There's no fluctuation when the tank is full. Also, when the truck is first started the indicator needle goes hard to the right then back to level. Anyone ever see these problems with the gas gauge or sending unit? Fixes? I'd hate to drop the gas tank again if it's not necessary. Thanks.

If the voltage to the camshaft sensor is good, then perhaps a knock sensor or the crankshaft position sensor? It certainly sounds like a timing issue, though a vacuum problem could also be the culprit.

the camshaft position sensor controls the timing in combination with the crankshaft sensor.the only codes im getting are for the camshaft sensor.po340 twice and po 341 .i'm thinking maybe i got a defective camshaft sensor.im gonna take it out tommorrow and try another one.

It sounds like the brake switch is not working correctly. That will keep it from up shifting correctly and kick the A.B.S light on

you have one injector that is shorted out. If one shorts they will all shut down.

try blocking off the return line maybe you have a fuel pressure regulator sticking.

do a stall test on the converter. The stall is maximum rpm will let the engine go. It sound like you have a bad torque converter

The hood is not sealing up by the cab and water is getting on and in the dist cap. Replace cap and hood seal.
