1996 chev. 3500 5.7 V.8 rack body,197,000 miles,automatic trans. Problem seemed to start when i turned left while going uphill. truck would loose power through the turn and when steering was straight again it would run fine. no codes were set.became worse over a few weeks until it stopped running on highway.first P1351 was set. waited and it finally started and drove home just fine. now it barely runs and sets P1351 at each start.Replaced ign. coil,ign. control module,throtle pos. sensor,crank pos. sensor. Fuel pressure is 53 psi.coil and module grounds are good.no sign of shorts or opens in coil/module area.ign.switch wires seem ok.I rember reading about this left turn problem in 90s P.U.'s

If that's your engine then fuel pressure is too low and would account for loss of power among other problems,
T
************************************************ Fuel System Pressure
For your 1996 Chevrolet Truck C3500 1 ton P/U 2WD 5.7L SFI :  60-66 PSI(Pounds per Square Inch) Note: Vent the fuel tank vapors by loosening the fuel cap. Position the ignition switch and the A/C system in the off position. Install a fuel pressure gauge to the vehicles fuel pressure valve. Confirm that no leaks are present, and with the key on, engine off verify the PSI reading on the gauge.

Thanks for the clue(fuel pressure) that sent me down a different path. When I checked pressure again it ranged from 28 to 60 p.s.i.. lowered the tank and found 7 quarts of water in the primary tank-water was being pumped in from the rear tank because the sending unit had rusted thru. Water sloshing around in the tank would starve the engine of fuel on left turns (not rights!) and it would loose p.s. pressure to the steering and hydro-boost brakes. brake accumulater was bad and had no reserve. It runs great now!! p1351 is gone now,but why did it show up in the first place? It seems unrelated to what was really the problem.

Egad! 7 quarts of water! Well that would certainly raise hell in it. If all set now, no coded and running right with things as cleaned up as you can just forget it and call it fixed.
I don't know off hand what that code was but any engine not running properly is going to throw some code and if it stays off ignore it now.
The assessories failing are due to a near stalled or stalled engine (low rpm) on belt driven pump so forget that too for now.
Do replace the fuel filter of course and I have to suggest another pretty soon too.
I haven't seen a bonefide water issue in a looooong time now as I'm conviced the alcohols used in the damn fuel we buy does take some of it out. It very well might have been the source you purchased it at but could have been over several visits over a long time too as the rust wouldnt happen on inside so fast or I wouldn't think??
Good luck. Congrats on finding that out,
T

P1351 is high ignition voltage. If it doesn't come back, no worry. It could have been set by a lean condition. It takes more voltage to fire a lean cylinder than a rich one. If it does come back, let us know, and we'll try and guide you from there.
