I have a 93 K3500 with a 454. Truck was running fine, started no problem, ran great. Driving the other day, turn the corner and the engine quit. Cranked the engine, fired up for 2-3 seconds then quit, ...


Before starting the engine, the fuel pump should only run for a few seconds when the key is first turned, to pressurize the fuel system. Even though the pump appears to be running, you may either have not enough or too much pressure for the engine to keep running (fuel pump or pressure regulator). I think it may just be a coincidence the engine quit while turning a corner, but the gas in your tank may have been so low it sloshed away from what is likely a very old pump, starving it and causing it to failure.

97 f350 5.8 disconnected fuel line from tanks to inline filter turn on key pump runs momentarily then shuts off only supplying small amount of fuel from either tanks


Generally speaking, its supposed to do that.
The fuel pump(s) is powered by a relay that turns on for 3 seconds when you turn the key on. If the engine does not start and produce oil pressure, thats all the power the pump gets. If you were in a wreck the pump would shut off when the engine dies even with the key on to prevent a fire.
You would need to jumper the relay to make the pump run beyond the 3 second time.

Wont start, no spark anywhere


Check the spark, remove the fuse to the fuel pump and remove one of the spark plugs. Connect the plug to its lead and position it well away from the engine against the truck frame (do not hold it) and turn the engine over, check the spark. If no spark it most probably a faulty coil. Check the impedance of the spark plug leads and replace any that are much higher than the rest. My guess is that you have spark but no fuel, What?... OK this is what I think is wrong. Your pump is fine when at position 2 on the ignition switch however when you switch to position three to fire the engine the power to the fuel pump is momentarily disconnected. A leaking fuel pressure regulator or injector would drop the pressure in the fuel line and at the same time flood the engine making it impossible to start. Once you start the engine with ether the ignition is back to position 2 and the pump can make good any loss in pressure but because the intake mix is rich this will cause the engine to run rich too. A good fuel system is capable of delivering 40 - 50PSI of fuel pressure and when switched off up to 90% of this pressure should be maintained for about 5 minutes, if it cannot check out the fuel pressure regulator and injectors. The fuel pipe should be capable of filling a pint pot in about 15 seconds, if it cannot check out the fuel filter is clogged.
Hope the above gives you some pointers

Ive got a 1997 cavalier it will start but quickly dies out ive got fire to my plugs and fuel to the injectures ive just replaced the ignition switch is there somkind of a security


You need a new fuel pump relay. The engine fires up and runs off the oil pressure switch untill the oil pressure PSI is reached at normal operating conditions. When the oil pressure reaches its operating PSI the PCM or engines computer will shut off that circuit and turns on the fuel pump relay to run the fuel pump untill you shut the engine off

Lost power to engine


Check make sure all plugs are firing. Sounds like what my 93 Rodeo was doing-Idled okay but very rough when in gear. Turns out only 5 out of 6 plugs were firing due to a defective ignition module- 100 bucks later it works fine.

Hope this helps.

I'd start with one of these and move on to the next.

Fuel
Spark.

Is it getting fuel? You should have an "in tank" electric fuel pump. When you turn the key halfway (just before turning the engine/starter over), you should hear the fuel pump prime. Easy way to check is to look in the throttle body while someone turns the key to the "on" position. You should see/smell the fuel. You can also listen to the gas tank while the key gets turned. You should hear the fuel pump run.

To check spark, pull a spark plug out, put it back on the plug wire and rest the electrode end of the plug up against the engine or exhaust manifold and have someone turn the engine over. You should see the spark plug firing. Don't hold the plug or wire while doing this. You'll get zapped if it's working ok.

If these both check out ok, then take a look at your firing order. If it's off by a significant amount, it may not fire. I've seen this happen when a cap/rotor/wires were changed and the wire/rotor was not positioned on the correct cylinder. (Most of the time they will at least fire or backfire, but either not stay running or run REALLY badly if the firing order is off.

My 1991 honda civic runs fine yesturday and today it wont start please help


the car wont start? do you mean the engine wont turn over or it wont fire or run? if the car does not run but it turn over, check the basic..see if you have sparks and fuel, then check all your fuse pertaining to engine and ignition. the car need to have both thing in order for the engine to run. If you getting both sparks and fuel you engine may have jump time especially with older car with high miles, it the sign timing belt getting worn, you don't want it to break. if you don't get fire from spark plug then you may have a bad coil,distubutor,rotor or timing sensor. if you get no fuel, fuse blown, bad fuel pump relay or fuel pump it self. hope that help some ..good luck
