2001 isuzu rodeo has intermittent starting problems

Loose or corroded battery cables. Also possibly a bad starter solenoid or starter. Clean and tighten battery terminals. If it still does this, remove the starter and have it tested at any auto parts store.

Hope that helps.......

Could be your fuel pump failing. Try this; turn ign key to "on", not "start" then off after 5 seconds. Do this several times then try "start". If it starts right up this time, your fuel pump could be going bad, or the fuel pressure is dropping for whatever reason.

Check your Fuel Lines and your Fuel Pump. (I just fixed a problem with my 2001 Isuzu Rodeo Fuel Return Line).

Also remember that in Rodeos, as soon as you turn your car key to turn the ignition on (just to make the dashboard lights go on) a certain amount of gasoline gets pumped to your engine in preparation of you turning the key all the way to crank the ignition and start the car. In other words, even before you turn the key all the way to crank the ignition, the Fuel Pump will pump some gasoline through the Fuel Lines to your engine (it will pump the gasoline for about 4 seconds then stop). So when you go to start your Rodeo, remember to turn the key with one continuos motion so that you start the ignition cranking while the gasoline is being actively pumped.

In addition, you should never turn the ignition lights on without turning the key all the way to start the engine. Doing so could cause that bit of gasoline that was pumped to start the engine to just sit there and create problems.

This is very common bad starter, replace the starter and the problem will be solved, some of these isuzu starter are a pain to replace, good day

Primary cause: a faulty starter relay.

Dirty terminals, happens all the time. Did you have the battery tested? Or just know it's OK? Did you check the water? How about the electrolytes? Get the terminals cleaned off with a wire brush, and scrape the insides, make sure they are tight. I have replaced more batteries this week, must be the weather. One was stone dead, 5 volts and still started the car?? Couldn't believe it, good car. The other 2 were dead with 12+ volts but wouldn't start anything, both got new terminals, and both got cleaned up. NO problems. Check it out. Lastly, the solenoid in the starter could be bad if everything else checks out, whack it with a hammer while turning the key, if it jumps, you found it.

get under the truck and hit the tank hard with your hand the pump may be stuck a couple good wacks might work

probably time for a new starter... no problems with the shift interlock ?

possibly the metal contacts in the starter have worn down and need to be replaced, I had that problem with my rodeo 90 model, had to keep clicking on the ignition key until it started, auto electrician said I need a recon starter $300+ dollars but I bought 2 new brushes $5 and put them in and had no more trouble
