Just washed engine bay 1jz...now it wont start

[vg7z]

After washing my 1jzgte and gettin it nice and pretty...I go to fire her up. It cranks, and cranks, and cranks.

OK, no spark no biggie. (Or so I thought). So I start troubleshooting. Fuel pump OK I can hear fuel through the fuel rail and theres pressure. I take the spark plug cover off and its bone dry down there. I check all fittings and electrical connection plugs and theyre all connected. 30 minutes of being frustrated and stumped go by so I turn to my last resort...online forum advice.

Any suggestions? Any help is appreciated!

Ignitor? Air Filter? You need fuel air and spark. You have fuel. You may have spark. What about air?

one thing for sure its not the ALT:rofl:

Carl from Slingblade saids you're out of gas.................:biglaugh:

Have you checked any fuses, like maybe the EFI? I don't really know, but it doesn't sound like it could be air causing it. My 1jz will crank without any filter or ic pipes on at all. Good luck.

Unplug the ignitor connectors and blow then out with compressed air. Also check out the fuel pump relay.

Happens all the time, probably the CPS (lower sensor at the crank).

It will dry off just give it some time.

If it was the ALT, the car would still start, obviously.

The CPS and igniter are the most important for the car to run, so that is what you need to look at.

For reference, you can totally unplug both cam position sensors and the car will still run. The CPS though, has to be working properly for the car to run.

i dont know if it is the CPS ? but on my car i just washed the valve cover and at first wouldnt start couple min later ran like shit took off the coil packs dried them off when checking for spark & the spark plugs ran like brand new. ignitors do not like to get wet!

 

[vg7z]

so it started this morning, but only on 4 cylinders. i took the coil packs off and dried em all off. it startred fine again, but shut off after 3 seconds. now itll jsut start, hit 1000rpm, and shut off.

any suggestions?

same thing happened to me. it took a few days for the car to run right again. it eventually got to where it would idle on it's own. i just left it for a little bit idleing, so it would get hot and help the water evaporate. i had water in the spark plug gally, which i didn't see cause of the cover.

i once applied a titan motorsports sticker on my ignitor and the next day it rained...the day after i took it out and the engine would die or cut out randomly...i took the sticker off and never had the problem again...im guessing it was holding moisture in there..could be the same problem but then again who knows...dry everything electrical

 

[jgdynamics]

usually after i clean my engine bay, i use a can of LECTRA CLEAN and spray it on anything electrical... it helps evaporate the moisture, i started doing this after my mr2 would go past 2500 rpm after washing it, i then took all connections and sprayed them, and plugged em in after like 20 mins, and ran perfectly fine! give it a try

[t4boost]

you Crack me up IJ

Make sure to get some Cramolin or Electrical contact Silicone. When you are checking all the connections and drying them out apply this stuff, it should help in the fiture to keep water dirty oil and moister out of your connections

 

[vg7z]

Shes alive! Runs perfect now, I couldnt be happier with a CLEAN 1j and running one.

Thanks for the input guys really appreciated. Im gonna take apart every connecter and apply the contact stuff.
