Question about 1989 Isuzu Pickup 2WD

1 Answer

1989 4cyl 4x4 Isuzu "Space Cab" truck won't start in cold.

I have a small Isuzu truck that will not start in the cold unless I have a block heater on the oil pan and a battery charger attached to the battery. It's a brand new battery. The O2 sensor light is on and I can't start the truck unless I keep the gas pedal to the floor, and even with everything hooked up to it, I still have to keep trying it for awhile. Please give me some insight on what you think it could be. Should I just replace the O2 sensor?

How to start 92 npr diesel in cold weather

You will probably need some Ether based starting fluid. You may have to remove air filter to shoot a 2 second blast into the intake - but first try shooting the air intake with the 2 second blast and start vehicle. Diesel fuel tends to thicken in cold weather and a fuel additive like Lowes diesel fuel treatment may help keep your fuel fluid in colder weather. In cold weather, like on a night of clear skies causing low temperatures, a block engine heater will help to keep your fuel fluid - along with the diesel treatment. Block heaters are not too difficult to install depending on your vehicles configuration and how much room you have at a freeze plug, and are well worth the cost.
Hope this helps and please rate my solution!!

Suzuki sidekick wont start... has power, but starter doesn't kick in... it does this intermittently... this is the second time... gave it a push start the first tim,e, and it worked good for about a week,...

ah ha.. you have the same problem i have.. and it was posted in december which reaferms it lol.. was it really cold out? and was it a standerd? sounds like it if you bomb started it.. but.. anywho.. i found that placing a heater in the cab.. just a lil space heater solved the problem.. mine only does it when it is really cold out side and hence inside the cab.. there is a switch on your clutch that will not let you start it unless the clutch is pushed in to the floor.. i found that this switch does not tend to wanna start when cold.. if it was your starter, changing position on the fly wheel. eg trying to force the drive train to move.. would cause your starter to catch.. not work then not work at all then work.. try that.. cheep fix compared to a starter
