the ecu is inside the car wasn't wet in there but it could of. I'm thinking it could of sent a spike bike to the ecu

How do I do that?

Aren't the VVT sprockets keyed to the cams? if so you should have no problem, the VVTs don't actuate during start up and low RPM so that wont effect things, low compression will hinder starting, so re check that. If the ECU has got water into it its entirely possible that this is causing no start as well, but check out the compression first. I think so but I was just thinking outside the box really just incase. I don't know what could be causing low compression. Gonna do a leak down test then after that it must be timing. Just had new head gaskets and bolts so I'm really puzzled. Still doesn't explain no spark though.still need help with that!

I'm 20 and went with elephant for £800 with a crash!

Yeah I am.. Yeah it is.. I haven't checked when I crank it but I'll try a lamp tomorrow on it. Think I could of fried the ecu going through the puddle or anything? I'm just hoping it's the vvt solenoid but don't think anybody knows?

Yeah I've went over them and cleaned them and re fitted them then done a continuity check to the the battery and all okay

Haven't tried that yet but heard about it. The low readings to me indicated incorrect timing or a bad valve overlap. The valves were all okay because I tested them before I put the heads on. The timing marks are perfect. I accidentally took the vvt gear pulleys off.. Could that affect timing? I've always got a leak from my vvt solenoid base so I've got a new one on order. Do you think that could make a different because it's not getting correct oil pressure? I'm grasping at straws here I know..

How do I check they trigger? I measure resistance through them and got a cranking speed when I plugged snap on solus code reader in so crank shaft must be getting a reading. Yeah compression is low but heard on another forum it's because I've rebuilt it and not run it yet, the cams and chain marks are all perfect.. Im in Whitehaven Cumbria. Far away from everywhere!

Continuity checked all fuses. Tested for resistance through the cam and crank sensors checked all connectors all on tight and pins aren't bent I took the full loom out the car to put engine back in as it was easier so will re check soon. The imobiliser works because I have to press it into a hole before starting the car. Anything else?

I have a Nissan 350z fair lady 2003 with 80k and it's an auto.. So after fitting a new conrod because I drove through deep water. I built her back up and the car started briefly for 3-4 seconds then cut out and wouldn't start again so checked for a spark by taking the plug out and putting it on the body and there was non but there was voltage to all coils so I checked resistance through the coils all ok Checked all fuses all ok. Checked fuel pump and plugs were soaked in fuel when I took them out so fuel isn't the problem. Tested crank and cam sensors all ok. Didn't remove flywheel so it has to be on the right mark, done a compressions test and all cylinders were 50psi which is really low? So it made me think I'd timed it up wrong so checked timing again before and took the chains off and done it again and it all lined up as fsm but still won't start.. Has no fault codes. Please help! Any ideas would be appreciated I'm totally stuck. Tried new plugs they didn't work. Any ideas what it could be?
