The 1993 350 came in three types: low compression, medium compression and high compression. The high-compression version of the 1993 350 came in the Camaro Z28 and Corvette. This progressed to truck running so rough even under no load that it stalled and would restart. Now the truck does not even idle very well in park or neutral and sometimes dies and then is very hard to restart. Then while driving yesterday same problem, but then engine reved, but truck wouldn't go. I cleaned the throttle body and installed a new cap and rotor old cap looked worn. I did have similar problem sluggish acceleration when I visited, to Ohio last Christmas so I changed out the fuel filter then and had no further problems.
I replaced the fuel filter, but problem remained. I tried shifting gears, but truck still wouldn't go. A tune up was done last year. When Chevy first released the Camaro in 1967, the auto maker also released the 350-cubic-inch engine. After shutting off, truck would not start. Maybe starter isn't kicking out the pinion gear? This version of the 350 came equipped with electronic fuel injection. One can't effect the other.
The 1993 Camaro Z28's 350, equipped with multiport fuel injection, produced 275 horsepower and 325 foot-lbs. Hope this post will help someone else in the future. Truck fired right up and is running great! Once in lot, truck would go into any gear. This engine had a 4-inch bore, a 3. I changed the oil, but didn't seem to make a difference.
I have a 1993 Chevy Suburban 1500 2-wd. I was also reading another post and I'm going to check the oil pressure too. What ever is easiest for you. Fuel pump was working and fuel was spraying into throttle body, but truck would not start at all. Any help is much appreciated. . Haven't had a chance to look at it too closely, having it towed to the house today.
Try to turn the crank by hand. It does sound as if starter is spinning, but nothing else turns when trying to start. I don't know if the engine is siezed, how can I tell? Since that time the truck has only gotten worse. I don't believe that the oil pressure gauge on the dash is not very accurate. The truck would sputter and lunge under normal acceleration and you would need to lightly feather the gas to go. A few days ago the truck would sputter under acceleration, worse with harder acceleration. Makes engine easier to turn.
I have repalced the fuel filter and checked for any intake leak, found nothing. Throughout its life, the 350 -- also known as a 5. The Corvette's 350 had sequential electronic fuel injection and produced 300 horsepower and 340 foot-lbs. The truck is a V-8 with 295,000 miles, tuned up last year. I don't know if these problems are related or not.
It will try to stall as soon as you put it under load in gear as well. No, oil pressure won't kill it, unless the engine sizes. That post suggested that if the pressure was too low that would act as a fuel pressure cut off. You can remove flywheel cover, use tool on flywheel teeth, might be easier to turn. It produced 190 horsepower and 300 foot-lbs. I was able to coast into a parking lot.
If the engine won't start because of the oil pressure switch, you have more than one problem. The check engine light is not on, by the way. Each model's 350 had a 4-inch bore, 3. I'll need to get a gauge to check fuel pressure. I installed a new flywheel and now I'm back to the sputtering problems. Truck makes wierd noise upon trying to start as if starter is spinnig, but that's it.
