hey guys ive just bought my first magna and it wont start.
i know quite a bit about motors and cars but all my experience is mainly on holdens.
ive be searching for hours on wats wrong and cant seem to get an answer.

it has spark and i tested fuel by pulling fuel line from fuel rail and tried to start it and lots of fuel came out
i tested injectors by puttin a circut tester on them and it was pulsing
i checked for fault codes and nothing came up
ive wiggled all the wires under the steering collum and pulled ecu out and still wont start
start ya bastard dont work either
im a bit stumped now so any help would be greatly appreciated thanks :)

checked Crank angle sensor? although that should throw a code.

ummmm if the CAS was not going then why is there spark and pulse?Also, Check for power at injectors, pulse is fine but the mistake manymake is they connect the power lead to a power source Such as the battery and check for pulse

Check that injectors are pulsing. Also check timing both of belt and ignition timing,

If you have spark, fuel and compression then check they are all happening at the correct time

So OP have you had car going at all, le did you buy it not running or did it drive to yours and not start again

Also, Check for power at injectors, pulse is fine but the mistake

ok i got the fuel rail off and sprayed sum start ya bastard down the port and still didnt fire...i tested spark and its still there maybe its not strong enough.
how do i test the timing...remember im not use to magnas and dont know where everything is lol thanks heaps for ur help :)

i bought the car not running but i known the owner for quite a long time and it was running bout 2 weeks earlier
he doesnt have the knowledge or money to fix it and was gonna sell it to a wrecker

just an update i took the dizzy cap and rotor off and gave it a clean put it all back on and ..no spark. so i took the dizzy out pulled it apart it all looked pretty good so i put back on i have spark but its an orange spark and doesnt seem to spark fast enough.
im gonna goto a wrecker and get another dizzy tomorrow and see if that helps. :)

Check the sequence of the spark plugs. Someone may have put the leads in the wrong place on the dissy cap.

Ill try that thanks....does anyone know the firing order?

1,2,3,4,5,6 from memory

Update the leads are on properly its got spark and fuel coz it caught on fire due to leaky injector no damage was done but still wont start lol

If you have FUEL, and you have FIRE, you must not have TIMING, check the crank and cam timing are right - if there are no fault codes it pretty much wont be a sensor - it will be plug leads in the wrong order - or cam and crank mismatch.

Have you checked the fuel pressure? If it is too high, it won't fire, injectors can leak, all sorts of problems.

ok how do i check if timing is right and how do i check fuel pressure
thanks for the help

The quick way (well assuming the engine isn't 180 degrees out) is to remove the front wheel and inner lining so you can rotate the harmonic balancer by hand (long handle 90 degree socket drive works well) remove the distributor cap and rotate the engine by hand until the rotor points just short of the #1 plug position - now remove the center front spark plug which is #4 but is on the same cycle as #1 but 180 degrees out of sync.

Drop a long shaft screwdriver into the hole and as you manually rotate the engine past #1 on the distributor the screwdriver should go up a bit then start to drop down - if so the engine is roughly in tune or possibly 180 degrees out.

to Check for 180 degrees out go back to the just short of #1 position and the use a bit of tight fitting hose to blow into the #4 plug hole - if the air goes out the exhaust all is good, if there is a lot of resistance the engine is 180 degrees out (Ie: Valves closed)

Hey guys sorry bout late reply been too busy to work on it and whether been crap lol...
I bought the repair manual and set the timing and it still wont start
I have spark and fuel and still won't ignite. ..it won't even ignite start ya bastard
So now im really stumped any more ideas

You need to take the car to a mechanic

You cant "set" timing so that in itself shows me that you really are out of your depth, you have done what you can and from here you need to get it fixed professionally

Is all and good having spark and fuel pulse, are they are the correct time, have you got correct comperssion, is there fuel flow. So many things can stop a motor from running

In relation to above post, how on earth can a 6G7 series motor be 180 degrees out, you could not even get the distributor back in like that for starters. As above there are many reasons a motor will not start, these need to be checked.

I dont have the money to get it to a mechanic also my friend who is an apprentice mechanic helped me do the timing.
We done the timing exactly as it says in repair manual. It did improve it alot.
I also got a multimeter and we tested the cas and coil and it all came up fine.
To me it seems as the spark isnt strong enough.
What else could be wrong any ideas and ill test them

Can't any 4 cyl engine be timed 180 degrees out? even on an interference valve engine? you can swap intake or exhaust etc etc no damage, but if you are trying to spark a cylinder that has the valves 180 degrees out of timing with the distributor the fuel has been exhausted out the - well - exhaust so no BANG! - rotate the cams 180 degrees so the fuel is compressed and BANG! your off.... or am I wrong?

It did improve it alot.

If it wasn't running before, and isn't after, what has improved?

Have you pulled the covers off and checked the condition of the cam belt?

If it wasn't running before, and isn't after, what has improved?

The engine has alot more compression..can hear it from exhaust...it really sounds like it's almost gonna fire just never does

Im gonna test the the fuel to see if its contaminated

Get a can of "Start-ya-Bastard" and spray a 5+ second burst into the air intake and crank the car if it splutters a few times it might be fuel - otherwise still something up with spark or timing.

I pulled a plug out and the spark had gotten even weaker.
I read the repair manual a few more times and found a few more tests for the coil.
And it failed so I got a dizzy coil rotor and cap from a car with only 150k on the clock.
I put it on and it started finally :)

I put it on and it started finally :)

Yay Good Day!

Thanks guys for all your help :)
