It all started with a bad tensioner. I replaced all pensioners, all sprockets, chains, water pump, adjusted timing properly, replace valve cover seals, intake manifold seals, both crank sensor, cam pos sensor, all new coils. Car will not start. Having issues as in my last thread. I rechecked all wires even pulled off cover an re did timing. This makes me think there is an electrical problem. Any help and or suggestions welcomed. Oh on cranking i pulled one coil to check spark i get one solid spark then it stops.

 

dead battery maybe? or distributor.

 

 

nope on the battery, maxi is distributor-less ignition.

car has new starter and battery

 

SES codes?

 

MAF sensor wont affect starting post *****.

 

I did not read your previous thread but are you getting fuel to the motor?

 

no codes. Yea new fuel pump we also did pressure test. Also did compression test.

 

I am at a loss really, it could be some type of electrical issue. Did you check all of the coils to see if they spark or just the one?

 

funny many part web sites list a distributor for a 2001-2002 vq3.5de engine. and i swear when i take the oil cap off i see a distributor drive end. but 2003 and on are distributorless. i'll take a picture and post it when i get a chance too.

 

Funny, 2001's don't have VQ35DE's. I have an 02 and no distributor....

 

the production date on mine is 9/01. i must be confused or i have a unique 3.5 hybrid .manufactured in japan. had the car since 2003 from the dealer at 0 miles. like i said i'll take a pic of what i believe is a distributor drive inside the engine. i dont mind being proven wrong and i know they are distributorless.

 

There's a difference between production date and the model year. You're car was produced on 9/01 and you had the car since 03 with no miles, so it sat for 2 years? Interesting. Btw, august and september is (are?) when the new model years start being sold. So you're car could very well be produced in 01 and be a model year 02 leftover bought in 03. If that makes any sense. What year does it say on the registration?

 

All coils get on soild spark when cranking then it stops. I havent tested the ecm, do you think it might be the cause.

 

Jesus Christ kids, all VQ's are distributor less, 95-(enter current year here)

 

I love it when people talk about replacing plug wires, too. I just LOL at their POS.

That's the only thing left, I suppose.

 

Maybe the computer is bad, it should keep a constant spark right? Otherwise it would have no way of igniting the fuel... I have never really had to mess with the coil packs. Have you tried to test the harnesses? I am not sure what they should read but I am guessing they should have a constant flow of power when cranking. I highly doubt its the actual coil packs it would have to be whatever is telling them to fire right?

I have been reading online about power transisors? I dont know if the maxima has one but some people have had similar problems and that fixed it. Or they said their ECM wasnt sending the correct signal to the coil packs?

 

Today Im doing testing the circuits between the ecm and and the crank sensors to make sure they getting proper voltage.

 

Good luck with that man. I hope you find a solution.

 

i know its not too much help, but you need fuel, spark, and oxygen to get it to start.

i'm really suspecting fuel. once after you crank on it, have you removed a spark plug and smelled down in the cylinder to see if you can smell fuel?


edit: ECU would be my next look, and it seems you're already going there... but if nothing was wrong with it prior? dont' know what would have killed it now???

 

^^ I am def getting fuel. Today I checked all sensors, ecu. sensors has proper resistance and proper voltage. All relays were check and they are good. Any ideas guys this car is really making me hate maximas.

 

I doubt this is it, but one time my buddy was putting new gasket on the manifold and he had shoved small towels into the intake manifold holes to keep shtuff from gettin into the motor since he was running out of time, the next day he installed it and forgot to take them out and we re-adjusted timing and tired 100 other things.

he eneded up selling it and the dude who bought it got a sweet *** motor (he paid 6k to have it built) for like 800 bucks cause he was so frustrated with it lol.

 

"What? It says right here that aleem is replacing us!"


Couldn't resist.

Bump for someone to help the OP? Any issue this frustrating has to have a super-simple cause, right? At least, that's what it always seems like to me when I'm doing something like debugging code or working on my car--it's always something tiny that my eyes roll right over again and again before.. voilą! something clicks and I suddenly notice the problem and fix it in no time at all.

 

lol
