Won't Start 1997 2.0 Gx

[mighty5855]

hi all newbe here got a issue with my rav4 its a 1997 2.0l and it doesn't start i have had look at spark which i have got when cranking, then fuel side which i have got up till injectors and thats where i am stuck with no fuel being injectored on crank checked voltage at injector ignition off 12v ignition on 0volts and it shows to 0.14volt when cranking. i have a code of 99 when i bridge E1 and TE1 any help would be accepted

since above checked some voltages now got voltage to injectors when cranking and it's 12volts. but still no start could this be immobiliser or could it be cam or crank sensor any info would be greatful .

My first guess would be the immobiliser - but then my experience has been with the earlier models.

Has the car been serviced - and did it just suddenly happen... ie running ok before? Is the car locking etc with the alarm fob ok?

hi i have just bought it there was one key and two fobs. One didn't work and one did, then both work only on unlock which is weird it may have been service as oil is clean but no history with it is there anyway around this ie. remove immobiliser/alarm system or are they ecu integral as toyota want £566+vat plus two keys at £27+vat and i was told there plug and play and keys auto program when put in ignition thanks

I don't think the alarm systems back then were very clever. Designed the best part of 20 years ago, they probably pre-date plug and play.

I personally would remove the immobiliser part - its basically 2 wires to the ignition system that are spliced to patch in the alarm system. If you are not to happy at playing with the wires, then I'd try a local auto-electrician or Jap car specialist. No point in a dealer as they will have no record or manual on the car. The alarm system is obviously faulty if the fobs don't work properly. The car is not worth paying £600+ for the alarm fix. If I was nearer, I'd pop in to sort it, but Derby is a bit too far.

Whats the mileage on it?

hi thats what i want to do would these wires be soldered/spliced into original wiring two wires ie. not cut in two or cut and a total of four wires bridged into the system i have a workshop cd manual with wiring the engine system is 3SFE does this make a difference with alarm and when i unlock car i can hear a relay click under centre of dash. And the milage is 101,000 miles thanks

just been looking and found this rav4 site: http://rav4world.com/forums/viewtopic.php?t=19174&highlight=immobiliser think this is as you described so i take a look and let you know.

The alarm is spliced into wires for the ignition, normally at or near the foot of the drivers side. Below the dash next to the radio (take a plastic panel off - easily done) there is normally the immobilser box...tied to the strut by plastic ties. Generally there are black wires running everywhere. 2 of these will run from the drivers foot loom across to the alarm ecu then back to the loom. Simply what you need to do is join the wires back together again bypassing the alarm unit.

Keep a note of what you do step by step in case you have to revert to the original wiring. It is pretty simple tho and if you're lucky will take less than 2 hours by the time you scramble about tracing the wires. From memory the wires are fairly simply spliced and no solder.

The units were fitted in the UK once the car arrived so you won't find the wiring on the wiring diagram.

finally sorted i traced it to the key and immobilier as the install was factory fit. The key had failed so i had lock smith reprogram eprom chip in immobiliser and he coded two new keys to that plugged it in and it started yay thanks to all who helped.

lucky chap - most of the alarms were fitted in UK by cowboys.
