Can be the distributor or maybe the fuel pump let the truck sit and then turn key almost on but not enough to initiate start up and see if you hear pump in the gas tank and if thats not it, it could very well be your distributor it might  be moist in the cap or button area

Ok I have replaced the Distributor, Cap, Rotor, checked all spark plugs and my 93 chevy c1500 is still jumping RPM'S when driving and will shut off! Can someone please help me??/


It could be a fuel problem, the pickup coil in the bottom of the distributor, or the ignition module among other things.
Someone would need to figure out if the ignition system is causing the problem or if one of the injectors is failing.

Sounds like the injector is not supplying the proper amount of fuel. Try unpluging the TPS first and then the IAC motor, both located on the trottle body.

We have a 1993 Chevy C1500 with a 5.7 that is dumping fuel at idle. We've put new injectors in it, new map sensor, O2 sensor, air control sensor, temp. sensor, new computer & chip, EGR sensor, Pickup...


something is creating alot of air to pass over the 02 sensor.


Low compression
Big vacuum leak.
Weak ignition
IAC stuck a little open.
TPS that is saying your foot is on the gas when it is not.
EGR stuck open a little.
Too low an idle
Weak spark plugs
Bad fuel pressure regulator
No vacuum to the fuel pressure regulator.
Bad coolant temp sensor.

What are the readings. Need to know the co and the hc reading in order to know if you have a misfire or an over fueling issue. All 5 reading are really needed to diagnose fuel related issues sight unseen

Why is my Chevy C/K1500 misfiring? It is not the spark plugs or spark plug wires those have been replaced. It is the number 3 Cylinder, what could it be?


Compression, air/vaccume leak, pluged injector.
My guess would be a bad injector, GM has an update kit for all of the injectors, with all new injectors, a body, and fuel regulator!

Hello;
The injector assembly also contains the pressure regulator. Since the truck has been sitting, you may have some corrosion in the regulator and the injectors. Try a fuel cleaner and the work on the regulator.

My c1500 5.7L has no fuel supply, autozone tested, bad OX sensor


Find out if that truck is equiped with a inertia fuel cut off switch, but I doubt that it is. Also have the fuel pressure checked, it might be a bad or weak fuel pump, or fuel pressure regulator.
