Thread: washed motor now no start

Check your air filter is not wet, if it is the hot wire in the maf may be wet, also check the TPS and the wiring plug for the maf also check under plastic cap in dissy for moisture or condensation, blow out with compressed air, good luck, Regards Frank.

Thanks mate, but the air filter is dry and so is the dizzy and all the leads. I just put in a set of new leads just to be sure and still nothing. Still giving a good solid spark and lots of fuel. In fact brighter bluer spark than my mates working disco which gives out only a orangish spark.

I already checked the MAF connector but haven't checked the maf itself. Still got my mates disco with me, so will swap out MAF's to see if that got anything to do with it.

Thanks for the reply though

Cheers

Check the ignition sense wire, its a small white/black stripe wire at the ignition coil, negative side. That and its associated resistor need to be clean and tightly connected to run. Its the way the ECU senses engine turning.

Ages ago I'd sprayed this stuff on the coil



Its turned into a hard sealed plastic coating on it. So every thing is hard and solid ( and hopefully water proof ) in its place. I don't understand much on how all the coil electrics works. But taking off the coil wire from the dizzy cap and arcing it on the engine gives a good pulsing spark.

I'm think that means its fine and dandy. Crossed checked Rave and thats what it also says if you got a good spark from the coil wire that means the problem lies on the HT distribution side.

I even put a old spark plug on number one wire and it also arcs a spark on ground so there is spark there aswell.

Fuel in the rail and plus petrol smell while cranking so I've got fuel aswell. Have floored it while cranking to stop it flooding. Sometimes the motor catches ever so slightly as if wanting to come to life and then goes back to just "hollow" cranking.

I'm at wits end as to what it could be I checked, rechecked and then rechecked some more everything I could think off.

Fuel and ECU relays, each and every fuse. Swapped MAF's, swapped dizzy cap, new leads, fuel, battery. Its been drying for a day and half now with the hood open and still nothing.

This is turning out to be one of my most challenging and longest fixes ever and all done in by a few squirts of water from a hand held sprayer ! Usually one gets to know what is shot but just diagnosing this is as what is actually wrong is turning out to be a nightmare in its self !

Take all the spark plugs out, dry them on a gas burner. Put them back in, warm to hot. Use some start-ya-barstud to get it spinning.

Oh and that wire I posted about below is important. Not because it causes spark, but because it transfers information to the ECU. No connect no injection.

Thanks mate. Its all dark now so will wait till morrow and that will also hopefully give it more drying time

I did the rave test 6 in the Lucas constant ignition section under electricals. Which say take the cap off and put the coil lead close to it and crank. There should be no spark and if there is spark that means that the rotor has a earth fault.

I did this and it does seem to spark every now and then, so could it be the rotor, but I was thinking all the rotor does is distribute the spark from the coil to the requires plug wire so it should kinda arc right ? Or am I wrong in this.

BTW I cleaned and rechecked all the coil connectors and still nothing.

Also now the other problem is how to get the rotor off and I live around 60kms from the nearest landy parts store and today is the weekend here. Is there anyway to remove this other than breaking it ?

Well apprently its a load of crock. My buddys disco does the same. The coil wire sparks on the rotor too, so thats not it.

For a second I was happy, atleast I knew what was wrong with it !
