i degreased my motor the other day, then moved it back to its spot... now ever since then it wont start. could i have shorted something out hosing the motor? when i turn the key it sounds like it wants to start... it just doesnt get there. any help would be great. cheers
Did same thing on my Honda I cleaned my Honda Integra engine and then NO go. I ended up getting a small amount of water/cleaner in the spark plug guides and the heat from the motor caused some condensation on the plugs = No start (but good "starting" sounds just NO start) RACT in Tas came out, once I told him what I did he went straight to the plug guides used compressed air to blow out the water and Bingo she started. He said if it happens again (which it will NOT) I could leave the bonnet open and let the sun evaporate the water out. I've since learnt my lesson - When cleaning engine I now use the Tech section "Engine cleaning" advice. Cheers Pete
Check your fuses in the engine bay. And clean the connectors as Pete noted above. Specially CAS and PTU.
degreased then hosed, thats how ive always done it and never had any dramas before. thanks for the advice guys.
you hosed a zed engine bay with a 20 year old wiring harness... there are no special water proof connectors on a z at all Good luck
ive established that the coil relay is clicking, but the spark plugs arent firing. does that mean the wiring harness is cactus? its all dry inside there though.
Did you pull the coilpacks? Check that you haven't filled the spark plug galleys with water. Found that even the slightest bit of moisture in there will cause the coils to earth out, rather than spark through the plugs.
Remove the coilpack. Firstly inspect the Spark Plug Galley for moisture. A compressor with air blower handy will make the job a lot easier. Inspect the coilpack also. Remove the lower rubber cap from the shaft and check for any moisture there also. Be aware that the spring loaded graphite connector at the end will come out. Dont Lose it. Got my money in you filling the galleys with water. Even though the Guides (or whatever they're called) are insulated, the slightest bit of moisture at the base of the plug will cause it to short out.
yeah ive pulled them all out, they are all dead dry.. so im truely lost now, if i had water in 1 of them it would at least fire up the rest of the cylinders but none are firing.
if u know someone who has a paint shop, then make them bake the car at low heat over night, that should dry everything up nice 40c (just dont leave anything in the car like aerosol cans and stuff like that)
Did something similar with my Zed some years ago (sprayed foam cleaner to degrease the engine) and managed to kill the crank-angle sensor. Result - cranked really strongly, but wouldn't fire! Swap it out for a known working one and see what happens.
lol thanks guys.. ill try that. and to nonesenze.. QLD is already a very hot place and its already been a week.. so im guessing its definately not a water issue.
It must have origionally been. Car started before, hosed engine bay (water got somewhere it shouldn't have), car does not start. Pull all coils packs, check ECU codes, possibly PTU or CAS.
What ecu codes appear? No spark or no injection? Remove the CAS and rotate it, do you get both injectors and sparkplugs ticking?
Are you getting spark? Pull a coilpack and spark plug out. Reconnect the wiring plug and insert the spark plug into the coilpack. Hold the end of the spark plug a could mm from the plenum and crank it over. If you get no spark between plug end and plenum, then I'd try a known working PTU... Series 1 PTUs have been known to die at any time. This could be a coincidence. Although its still possible that the PTU was hot and a splash of cold water could have killed it...
