Idle reset my truck has a problem the engine revs real high then real low ect.When you try to put it in gear it dies its getting fuel it has spark and the engine smells real hot after only running 5 min anything could help at this point Also the fuel pump gets stuck on And it sounds like a clicking noise coming from the cap and roter area did just replace cap and roter thank you

aLL FUSES GOOD.
all cold engines race high ,engine cold and the more cold the more high RPM. 1500 is PAR for RPM cold, is yours higher?
black SOOT is a huge bad RICH sign. of greatly needed engine service.
no code told P03xx what is XX.? (sad face)
we can';t guess codes we need to see them. sorry and all off them.
I thank also your scan tool is not certified for GM OEM scan codes.
P1xx up.p2XX ?
or is super old scanner useless
or just cheap $17 code reader ? also useless in the real world.

also did you know P0300 to P0306 means misfire. (weak combustion) lots of clauses.
ever do full tune up, in 20 years, spark plugs , spark wires
distrib. cap and rotor? ICM bad,?
?????
Map sensor clogged
IAC valve stuck open , RPM not regulated.

Fuel pressure was low, how low?, not told PSI
low does not cause rich burn but sure lean burn and misfire sure.
spec is.fuel real PSI test is 60-66?psi. RUNNING engine.
if not pump or FPR are bad. yes pumps can fail weak easy.
the test is called the Injector fuel pressure balance test in the SM, service manual.
the rules are.(gas)_
1: good engine, (compression at spec) EGR not stuck open and CATS not melted closed.
2: spark good, we can not burn fuel with dead or weak spark.
we call this a tune up,. (or doing the service points (today)
3: bad fueling, last fuel is last. in the due to Physics.
bad fueling can be caused by (short list)
bad MAF , or MAP, FPR, PUMP, or injectors leaking or clogged.
IAC stuck makes idle controls dead.
to find it take real tools , and gauges, a real scan tool , 2008 or newer OBD2 scan tool is best, for sure GM rated
GM has its own OEM factory codes. (vast)
or get the car serviced in a shop.,,, Bingo they have the tools!

here is your spark schematic
all these can produce P03xx codes too, but was never told.

when did it last run good, last week, last year or nobody knows/
that is good one, odd for sure that. NO scan tools work 1995 ,
2.4L stick shift. M/T
well the engine has no idea at all what gear you are in.
so my guess is, yes engine is overloading, (reverse is better )
means engine power is super super weak.
because REV has a higher numerical RATIO gear. than 1st.
so seem have more power. in REV.
sputters up is not a norm car term, but can me 2 things

• gross engine misfire.
• or the clutch slips. (RPM Rises but MPH goes slower.?

the engine dies/ DEAD, 0 RPM? that be>>>>
MY BEST GUESS BLIND, IS ENGINE IS:

• ENGINE IS FLOODING , SMELL FUEL? injector leaks.
• SPARK IS BAD,
• OR FUEL FLOW LOSS. LEAN BURN STALLS.
• Bad fuel, (old fuel was there before or now?).

there are lots of actual caused (parts bad)
spark parts all are old aND NO GOOD NOW. PLUGS/WIRES HV,CAP ROTOR HAS DISTRIBUTOR? YES IT IS.
BAD FUEL OR LOW FUEL PRESSURE OR CLOGGED FUEL OR AIR FILTERS.
all above assumes actual engine is ok, compression tests pass.
that is all I can figure out , not seen or driven me.
I can no see RPM and MPH dials or hear the engine sputter.

There are a few possibility on this one. If you run it out of gas or really low on gas you could of sucked junk up from the bottom of the tank and you will need to replace your fuel filter. Another is that your fuel pump us going bad and you would need to check the pressure. Your throttle position sensor may have gone bad. Your idle control valve is another. Your map sensor or mas sensor could be bad

Sounds like a spark plug or wire issue. Anytime the vehicle starts to skip, die, or (run rough) its usually these minor things. However if that does not help, start looking into your fuel system. Always try cheapest first. Plugs and Wires....Good luck...

sound like fuel filter stopped up.if you have distributor type engine your idle speed could be too low and ignition timing off a little.

Need to replase your throttle control sencor. The is what tell your cars computer to excelerate. . It could also be your fuel filter .But your make was common to have this problem. Take to a parts store near you and they will test for free. And you will know for sure. Wish you the best of luck.

if you have'nt replaced those spark plugs and wires lately, you need to.and also, lucas fuel treatment, in my personal opinion,is the very best for unclogging fuel lined and injectors.it being below a 1999 model and your check engine light is on, you can have it coderead for free if you're near anautozone or advance automotive parts store. they will code read it and tell you why that check engine lights coming on.hope this helps and thank you for choosing fixya.com

DO A LITTLE TUNE UP.CHANGE SPARK PLUGS.CHANGE FUEL FILTER.CLEAN FUEL INJECTORS.FILL FUEL TANK UP.AND ADD A BOTTLE OF FUEL INJECTOR CLEANER IN FUEL TANK.WHEN YOU DRIVE CAR AROUND.THE INJECTOR CLEANER WILL CLEAN OUT FUEL INJECTORS.IF CAR STILL RUN ROUGH IN DRIVE.YOU COULD HAVE INTAKE LEAK.

your engine is running very lean. you may have a vacum leak, bad injectors, fuel pump, mass airflow sensor ect. do not continue to run the engine or sever damage will result

I would recomend replacing the fuel filter make sure to prime with fresh fuel before reinstalling. give a check over oil condition ,air filter ect...
