I have a 1998 isuzu hombre pickup and early mornings or when the engine is cool the engine cranks right up but it seems when the engine gets hot it will turn over several times before cranking and when it does crank it is flooded you can smell gas.any suggestions on what might be causing this?

what engine, THE CAR IS A GM s10 IN DRAG.
4.3L v6 Vortec 4300, GM
2.2l i-4, OHV ENGINE. NOT ISUZU!!!

In 1996, Isuzu replaced its Pick Up with a version of the Louisiana-built Chevrolet S-10, the Isuzu Hombre, based on the Brazilian market S-10
so google the vortec 4300
here Ill type for you....

on most v6, its near the oil gallery , on a bank.
so that means if youd look on both banks , the one with the 1 wire sensor is it.
but not this v6
its here.
log in to mitchell's and read, its all there.

breaks = brakes?
the brakes use vacuum but never changes it.
so...... if it does, the booster diaphram is cracked.
OD, can be just a bad OD. switch or more complex.
did you scan the TCM yet if it has one?

why state vacuum high, then not state the values seen?
you connect the gauge, and it reads what? 19inches HG at hot idle is common.
or 0.64 bar (outside usa you use BAR) as you said pressure word for vacuum and is ok in pure science that word) but make me think yoiu are not in USA? or Canada maybe....????

i bet vacuum is just ok.
the issues are with the transmission and its controls.
post is older, are you still having issues.
do say and we can link you up to FSM information on 0D.
the book covers this.... ever see a real FSM before.
the real factory service manual,, (buy one, and win?)
or if in USA , alldata.com is #1 online version of same.....
there are others, but nobody ever posts the country
making most answers wrong, including MINE.

i only have questions, after all im blind cant see car nor open hood.
so... what engine is there, transmissions match engines. so....

omg its really a chebby. Chevy
The pickup was also sold by Isuzu as the Hombre from 1996 through 2000, but only in North America
its not ISUZU at all.
you should know this and post to chevy, S10
2.2 liter or 4.3L engine
my guess is 4.3L with Brazil front sheet metal.

there are 12 control lines from the PCM puter,
and the transmission,
to find out why the OD fails
we first check all fuse..... (on all electric fails we do that)
then check levels hot, by the BOOK.
then scan the PCM for transmission errors, P07xx ? codes>

i look at the alldata. com at the Hombre 98 , pcm page.
schematics.
od .
we make sure no errors from PCM
then check the switch, to PCM for OD active.
if the input is ok.
then we check the solenoid voltages in OD.
if correct then the problem is ok, outside trans, and not inside.

This trans is electronically shifted.
and uses a computer (TCM)
so inputs must be right to TCM
an outputs correct. if not , never blame the tranny first.

run fault codes and look for a faulty ambient temperature sensor as if it is faulty the ECM will not know to enrich the mixture ( like pulling on the choke)

usually a temp sensor on its way out. engine thinks it has cold air coming in so adjusts for that. but when warm air comes in the engine uses more fuel than it needs so will take longer to start. could also be the maf is dirty and needs cleaning as same as the MAP sensor, when replacing a dirty air filter its best to clean these parts as the muck that has been able to get through the filter will coat them with muck. this changes the sensors readings can become lower or high depending on the condition or evaporation in the air.

you have a DIS (direct ignition system) it consists of a coil pack,ignition module,crankshaft position sensor and ECM. there is 2 on your vehicle. if you have no spark check your crank sensor or ignition module. or goto local auto store and get a spark check for 5 bucks which plugs inline of the plug wires either at the coil or plugs.hope this helps

Bad sending unit attached to fuelpump or most likely a crimped or chaffed wire to it, either inside the tank or outside.

Try http://www.helminc.com. It should be available on Print on Demand.

need you have system checked to get trouble code to many things will turn light on to guess

You need four things for an engine to run. 1. fuel 2. spark 3. compression 4. timing (spark at the right time. By your post it seems you have fuel and spark and you probably have compression unless you blew a head gasket. That leaves the timing. Check the timing and/or the timing belt or chain whichever you have.

should be between the crank dampener and the block, i mean they are all relatively the same on all cars should be the only wires running close to the crank dampener
