1992 dodge d150 Engine spits and sputters, I have an 1992 dodge truck, replaced so far, crank sensor, coil, plugs, wires, cap, pick-up, rotor, oxygen sensor. The truck will drive and run great most of the time, then at times it starts to kick and backfire and loss all power, if I push the gas it bangs and spits, feels like an old doge I hdad when I got water in the distributor, same running problems, I can turn the truck off and it will start and run a bit better but with problems, nect day I can go out and everything is fine?

SOURCE: starting and running problem

Breaking up like you described can be related to a condition where the distributor drive gear is wearing out.
Had you checked it for rotor tip travel (about 5mm of loose travel is the max) or had the distributor indexed? The indexing procedure appears to be similar to an ignition timing adjustment but isn't the same.
Chrysler TSB 18-08-93 Rev A describes a condition often seen on the 1992-1993 3.9 engine. The distributor drive gear wears out prematurely and then wallows out the support bushing in the engine block. Your oil pump is driven by the same gear through the distributor shaft, so cold engine operation often is worse from the higher viscosity of the oil and the resulting load it places on the worn parts.
The distributor index slips to the retarded zone (trails what it should be) just from the gear wear. Adding in the worn bushing and chain stretch can put the distributor in a position where ignition cross-firing can occur and the switch plate (cam sensor) within the distributor can drop out-of-sync with the crank sensor.
If you haven't done so, check this out for me. Remove the distributor cap and twist the rotor clockwise and counter-clockwise. The total tip travel should not exceed 5mm, which is just about 1/8". Even if it exceeds this, an adjustment/ indexing of the distributor will get it running right again if only for a short while.

The first thing you need is to have the unit scanned. Check things like the baro sensor,map sensor,coolant temp. and the TP sensor.Also check your fuel pressure,volume and injector spray pattern. I think you will have found your problem,but if not hit me back with engine size and any codes,Good Luck.

The carburetor spits when its flooded - so something must be wrong inside it. Since this is the second time it has stalled when turning left it appears that the level in the bowl is higher than it should so the mixture is way richer : turning left pushes the fuel to the left in the bowl, making the momentary level even higher over the jets so the mixture gets so rich that it can't be lighted anymore so the engine stalls.
You will have to dismantle the carburetor, check the float for leaks and readjust it before reassembling it. While you are there check the size of the jets, they might be larger than normal.

Car will crank there is no spark have replaced coil and condenser

Test the ignition system output, ignition systems can vary in configuration but operate on the same principal. Ignition systems can consist of a coil, pick up coil, crank angle sensor, cam angle sensor, spark plugs, spark plug wires, distributor cap, ignition rotor and a distributor and any variations of these components. An ignition coil is a voltage stepper coil that transforms a low voltage (12 volts) signal into tens of thousands of volts needed to jump the gap of the spark plug.

This coil is activated by an ignition module triggered by using the camshaft/crankshaft angle sensor; timing is adjusted by the PCM (computer).This primary electrical signal is generated by the PCM which calculates spark timing by using a variety of sensors including coolant temperature, mass air flow, and oxygen sensors. Go to 2carpros.com for a video on how to check this using a 12v light tool. On the engine repair section search, type, "engine cranks but will not start." If my answer helpe you, please leve good feedback. thanks

5 years ago for cap & rotor???? It sounds like it's in dire need of a complete tune up - plugs. wires, cap, rotor, all fluids & filters ESPECIALLY fuel filter. I'd start there and run a good fuel system cleaner through it. Do your tune ups more frequently like every 30K - not wait 5 years!
