    ive been an auto mechanic for 25 years and never had one stump me this bad. my engine is 2.2 with no dist cap and rotor so it isnt that and ive checked timing belt and timing marks and both are good. i guess it si possible for fuel filter to freeze due to moisture especially the way gas is made nowdays.

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)

Well, could be many things, but first and easiest, check the dist. cap and rotor, and all the plug connections. Any moisture will freeze and short out the ignition system. Also change the fuel filter. If you get the slightest moisture in the fuel it will lock up the filter when the water freezes. Could be a relay, probably "engine relay" that sticks when it gets too cold.

Some starting points I hope.

SOURCE: Isuzu Hombre pickup, 2.2L Vortec, Won't Start.

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.

SOURCE: cranks, but no start. spark and fuel good, no

cam timming is possibly out due to gear reduction set up in heads
suggest remove rocker covers and make sure cam lobes are in this possition as well as all other timming marks luckily these engines (V6) are free wheeling (wont bend valves) set up like pic below

My 1994 Isuzu Pickup wont start when its below 32 degrees. Ive changed the gas filter, fuel pump, it just doesnt want to start when cold.


Below 32 degrees ( Fahrenheit , I presume) can cover a wide interval of temperatures. It could be the battery. You should consider installing a battery with a higher cranking power. In the colder parts of Canada, people install an engine warmer contraption. The device is kept connect to an electrical outlet overnight. In some places, it gets so cold that electrical outlets are available at some parking spots.

1996 izzuz hombre ... turns over wont start sometimes . sometime does start. when start runs real rough, missing. things i know - new starter, new fuel pump, doesnt fire on 1st spark plug and no one know...


Your problem sounds like the distributor, points and pig tail wire.
I suggest you try changing the distributor / servicing the points and pigtail wire.

The reason why p 1 inst firing is cause it isn't getting any power from the distributor. because of this it has the ripple effect your experiencing.

1998 Isuzu Hombre 2.2L cranks but won't start.


After trying to start, did you pull plugs & inspect them for wet from fuel, as you said you smelled fuel like it was flooding? Also keep in mind MAP sensor also provides info to VCM which then regulates fuel delivery & timing from info supplied by MAP sensor.
