please help wont start after engine change

**mazdamatt** · 5-10-08, 13:48

put in a 24v probe engine it ran in the probe and my mx6 ran before, changed dizzy to test checked the wires, the only wire i not connected it the one on the power steering pump? please help

might i need a probe ecu

Using original dissy ?

cranking ok ?

Fuel delivery ?

Spark ?

Check the ENG/INJ fuse in the engine compartment fusebox. If the 6 is a post 93, ensure the crank position sensor has been connected at the top of the dipstick. All earths good .. plenty of possibles.

Hi Matt
not 100% shoure but the probes ecu is slightly different to the 6,s so my guess would be yes,and depending on the year it will have the immobilizer in it so you may need the keys as well,, there again i could be wrong,,,,

i now its not answering your question with facts,just what i now,,,

Cheers Lee,,,,

**mazdamatt** · 5-10-08, 14:56

the probe and my mx are both 95's, no chipped key ignitions had the same dizzys, no imobilisors, could it be a dodgy crank sensor as i changed it?

**Oddball** · 5-10-08, 15:39

engine placed in a mx6 engine bay with mx6 wiring loom = mx6 ecu.

I would try the crank positon sesnor, also check for any codes ...

Paul.

**mazdamatt** · 5-10-08, 15:42

ok would it show codes with out running?, i have a spare crank sensor will swap it tomorrow, so we rule out ecu then, i had the probe dizzy on which worked, same one as my car, then i put my car dizzy on that works but stil no joy

mazda1109 · 5-10-08, 15:43

Hi Matt,,, you can test it with volt meter ,unplug the crank sensor and check the resistance between the two pins should be around 520-580 ohms, if not replace it,or try the one you changed it for,,,if its all ok could mean that the dizzy cmp might be faulty,,there is a way of checking that also but im not up to date on that sorry,,also as i found out the hard way check the timing again ,John told me to check this again and he was right ,

Cheers Lee,,,,

**Oddball** · 5-10-08, 15:44

Yep, should show codes .. pre engine start checks should highlight the fault.

Paul.

**mazdamatt** · 5-10-08, 15:45

its no spark, fuel is fine, checked everything, egr is not plugged in but my other mx is not either, all earths seem good, car did run and the engine i put in is out of a car i had that ran, i did change crank sensor before fitting engine, but the one i put on was off a car i had running 2

**mazdamatt** · 5-10-08, 15:47

ive tried 2 dizzys that i know work, do u mean set dizzy timing, i have not touched cam belt

**mazdamatt** · 5-10-08, 15:48

whats dizzy cmp?

mazda1109 · 5-10-08, 15:54

on a 93/97 dizzy there is a cmp ,crank position sensor inside ,but this normally controls the fuel injectors, and will bring up a coed ,but you said you have fuel so this should not be the prob,,,

Lee,,,,

mazda1109 · 5-10-08, 15:59

no ment the belt but as you say it has not been touched,,

Lee,,,,

**Oddball** · 5-10-08, 16:14

crank position sensor was removed from the distributor from 94 onwards... if you were running a 92 or 93 loom, ecu and dizzy, the engine would still fire as it would still have one giving a reading.

I think its the CAMSHAFT position sensor within the dizzy, that is used for the fuel injection, and should it fail, it will just fire all 6 injectors.

Paul.

**mazdamatt** · 5-10-08, 16:49

ok cool, must be crank sensor or bad earth then, ill have another play tomorrow, want to tax it monday so hope it works
