G'day,

I have a 1600 with an FJ20DET and it turns over, nearly fires up, but just won't start.

The Microtech MT8 has a red light flashing slowly indicating a fault, any guesses as to what this could be please?

Thanks,
Grant.

Have you had a look on their web site?

have you tested if the plugs are firing? is fuel making it's way to the injectors?

Yep, checkod out their website/manual, and the warning light is due to a sensor error. I read it could be due to a sensor not being connected such as a water temp or air temp sensor. Does the FJ20 have any sensors not available such as air temp?

With regard to the fuel to the injectors, I pulled out a spark plug and it has a strong smell of unburnt fuel, so I guess it's getting in there. How do I check the injectors are getting fuel?

thanks.

Sounds like no spark then - the faulty sensor may be the crank angle sensor

I checked one lead to a plug and it was sparking.

Would a faulty crank angle sensor stop it from firing up?

I'm not sure about FJ's, but my daily driver Golf had a dodgy crank angle sensor and the thing used to stall at red lights and then fail to start again, so possibly.

Thanks for the replies.

The low pressure fuel pump does not seem to operate either when the ignition is on, or when I disconnect the wires and hook it up directly to a 12V battery, no vibration, no noise or anything?

Surely there would be some noticable response such as noise or vibration when connected?

(There is a fuel filter after the high pressur pump which is still full of fuel after turning it over a bit?)

That low pressure pump seems to be buggered at any rate so I will replace it and see what happens.

Would this Carter one do the job P4070 ?

Thanks.

Pretty expensive for a low pressure pump.
I think the one I used was a Carter.
Cylindrical in line jobby.

You will probably still have a sensor fault. The ecu doesnt monitor the fuel pressure/pump afaik.
If it hasnt worked for a while the pump might just be stuck like injectors do when they dry out.
Give it a good clean with fresh fuel before you waste money on another pump...
