Hi,
I am new to the forum, theres really good details over here I need some help on my pajero not starting.

The paj was starting and running perfectly but lot of carbon build up so I cleaned it up, took out the inlet manifold, injectors and injector manufold cleaned ERG valve and throttle body, tps and air cleaner once put all back now it's not starting, cracks but not starting, checked the ohms and set tps to 0.50 ohms but still no luck, please help if anyone had same issue.

Thanks

As you have cleaned the injectors did you re-prime the fuel connectors to the injectors ? You might want to crack the union between the pipe and the injectors one at a time and check for fuel at each point you might have an air lock in the fuel system.

its a petrol Simon not a diesel..things that need to be checked,are all electric connectors connected properly,is there a spark at the plugs,is fuel getting to the engine from the tank thats the basics after that it could be things like crank or cam sensor problem but exact year and engine would help as there are different variants of the 3.5 engine is it a gdi does it have 6 coil packs or just 3 Question

It started fine before cleaning the ERG and throttle body.

did you reset the throttle body??if not disconnect the battery leave it for 10/15 mins then reconnect it turn your ignition key to dash lights on only no engine run then switch of (this needs to be done within 1 second) then wait 15 seconds turn the ignition to lights on again wait untill all the ticking noises stop then try and see if it starts if it does run the engine upto full temp then switch of then repeat the first 2 steps again..

Hi hutchy,

Tryed it did not start, cranking and had a backfire noise but not from exhaust from front I think from between throttle body and air intake.

Have no idea.

The wires that connect to the coil packs, must have switched them around, try switching them, left bank to right bank and see what happens. Once had stress for two days because of that. Gave a misfire around the maf sensor

Hi Guys,

Finally it started Very Happy

took all out and went over one by one now all good except went for passing and failed emission test fail, any work around this to get it passed.

Thanks

change the oil and filters clean the egr valve,put some injector cleaner in and give it a good hard drive once up to temp and then try the emissions,
