My k reg toyota previa(import) wont start

Question edited for clarity.
Question moved to model Category.

If it cranks, it _does_ turn over. You are cranking but not firing or starting.

Does your vehicle have an anti-theft alarm and immobilizer? Is the battery light on, or is it the anti-theft light? If so, it needs to be reset when you disconnect the battery. It sounds like you have a battery issue, or a battery charging issue. Your best bet is a mobile auto-electrician with a pro grade scan tool computer to correctly diagnose.

The link is inconclusive regarding an immobilizer, but I bet it has one.

Starter motor or solenoid could be at fault check the battery is fully charged first

When this happens, move the Gear Selector lever a bit. It has a Neutral Safety switch that may be slightly out of adjustment

If the eng. Is cranking over could be spark or fuel or antitheft is enabled is the antitheft light on or is there an aftermarket alarm antitheft device installed on vehicle?if you have a key fob try changing the battery in fob.

Hello; O didn't see the important one. Fuel? Turn the key on and wait a few minutes . The fuel system building pressure may help. If not, Make sure it is getting fuel (fuel pump humming. Good Luck _N_

if the lights on the dash are also lit. The problem is not with the radio it is with the multifunction switch Turn/light switch try to remove the fuse for the dash lights

common problem the lock wears out and wont turn a replacement lock at auto parts store is about 100.00 dollars problem is if you have a transponder key the new lock comes with a plain key so when you change it the car wont start the way around this is what i did 2 months ago to my own car 1998 camry ( same car ) you need to take the bottom cover of the dash under the steering column off there is a little hole in the steering column under the key lock its a button up there your supposed to push when the key is in the on position but the problem is it wont turn so you have to drill it out its a hardned pin to prevent theft use a cobalt drill bit i think its 3/16 or close to it before you do this disconnect battery remove the little box from key lock under dash it has small phillips screws and the electrical ignition switch from the back of the ignition lock than drill till you can pop out the ignition lock you have to pop off the cover around the lock it has the green coil light in it when you turn on the key it lights thats the transponder coil for the computer now turn the key in the new lock on and slide it in reassemble everything connect battery turn key make sure it cranks but it you have anti theft key it wont start cut your old key apart carefully and take out the transponder chip cut a hole in the new key to glue in the chip and car will start now if you have transponder key you are looking at about 600.00 from dealer if you have a standard key its about 400.00 hope this helps

This could be a grounding problem. Check all battery connections. Also check motor to body ground strap for corrosion. Check battery to motor ground and battery to body ground. Even if the ground looks allright it can be corroder underneath, so you have to take the ground bolt off to clean it.

sounds like you poped the main fuse in the under hood fuse panel. before that the battery light on in a toyota pretty much points to an alternator problem.

Got the answer now thanks
