Thread: Td5 not firing

The crankshaft position sensor is in the same loom as the injectors so its possible. Almost the 1st check when TD5 is malfunctioning is to check for oil at the connector at the front of the head.

it can also be caused by a fault with the security system.

Check the battery voltage is up over 11V (11.5V even) before trying to start and that the terminals are in good nick. Also check your earth and positive feeds from the battery terminate OK.

Try pushing the cut out switch on the passenger's side fire wall, it can stick.

When a new filter was put in, did you prime the system? Instructions are in the owners manual (for running out of fuel). Basically turn ignition to run, hold accelerator to floor for 20 seconds, turn off, repeat half a dozen times. Then try and start.

As for oil in harness, if there's nothing visible at the plug, take off the rocker cover and remove and clean the harness if unsure. But I would expect a miss-fire or running rough, not a fail to start.

Don't remind me That's why I bought Rovacom several years back. However this will most likely either trigger the alarm when trying to start or at least flash most of the dash lights - from personal experience.

Thanks for the reply's, It happened after the car had already been driven about 500ks with the new fuel filter so sure its not that but tried new filter anyway.Its not the battery or the voltage as I tried 3 different batteries plus a jump start so ruled that out.Overhauled the starter with new brushes and solenoid.Didnt know about the reset switch but as the car is now at the fuel injection mob will wait until they open and check that.Only other thing was a TRS upgrade ECU about 6mths ago so unless that has failed..Time to buy nanocom.
Thanks again,Cheers Ean

Just a follow up to what the problem was...A completely seized idler pulley.The car had been serviced 3oooks before and pulley's checked and new harmonic balancer and belt.The pulley must've been seized for a fair time as it melted the center of the pulley and started to melt the new belt.Total all up.. recon starter..Fuel injection test.new idler pulley..new belt.
May help someone who has similar starting problem in future.Will post pics of pulley when I work out how.
Cheers Ean
